DescriptionThe SparkFun 3.3V FTDI Starter Kit gives you just what you need to get started with FTDI FT232RL USB to serial IC. The pinout of the included board matches the FTDI cable standard to work with official Arduino and cloned 3.3V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.The SparkFun FTDI Basic Breakout was designed to decrease the cost of Arduino development and increase ease of use(the auto-reset feature rocks!). Our Arduino Pro and LilyPad boards use this type of connector.The included cable is a USB 2.0 type B to Mini-B 5-pin black cable.

DescriptionThis is SparkFun Beefy 3 FTDI Basic Breakout for the FTDI FT231X USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards. It can also be used for general serial applications. Built upon the same foundation as our 3.3V SparkFun FTDI Basic Breakout， the Beefy 3 is equipped with an AP2112K voltage regulator making this FTDI basic breakout board capable of handling a current load of up to 600 mA! With the addition of a more "Beefy" voltage regulator your will now be able to power a 3.3V project directly from the FTDI. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards.This board brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector. The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black wire on the FTDI cable is GND， green is DTR. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.There are pros and cons to the FTDI Cable vs the FTDI Basic. This board has TX and RX LEDs that allow you to actually see serial traffic on the LEDs to verify if the board is working， however this board now requires a Micro-B USB cable. The FTDI Cable is well protected against the elements， but is large and cannot be embedded into a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the FTDI cable uses the RTS signal.This board was designed to decrease the cost of Arduino development and increase ease of use(the auto-reset feature rocks!). Our Arduino Pro and LilyPad boards use this type of connector.

DescriptionThe SparkFun NEO-M9N GPS Breakout is a high quality GPS board with equally impressive configuration options including SMA. The NEO-M9N module is a 92-channel u-blox M9 engine GNSS receiver， meaning it can receive signals from the GPS， GLONASS， Galileo， and BeiDou constellations with ～1.5 meter accuracy. This breakout supports concurrent reception of four GNSS. This maximizes position accuracy in challenging conditions increasing， precision and decreases lock time； and thanks to the onboard rechargeable battery， you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally， this u-blox receiver supports I2C(u-blox calls this Display Data Channel)which makes it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system， no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.The NEO-M9N module detects jamming and spoofing events and can report them to the host， so that the system can react to such events. A SAW(Surface Acoustic Wave)filter combined with an LNA(Low Noise Amplifier)in the RF path is integrated into the NEO-M9N module which allows normal operation even under strong RF interferences.U-blox based GPS products are configurable using the popular， but dense， windows program called u-center. Plenty of different functions can be configured on the NEO-M9N：baud rates， update rates， geofencing， spoofing detection， external interrupts， SBAS/D-GPS， etc. All of this can be done within the SparkFun Arduino Library!The SparkFun NEO-M9N GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the NEO-M9N. This reduces the time-to-first fix from a cold start(～24s)to a hot start(～2s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time.This product requires an antenna：Be sure to check out the related products/hookup accessories and pick a suitable SMA antenna for your project.The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.

DescriptionLIDAR has never looked so good! This is the LIDAR-Lite v3HP， a compact， high-performance optical distance measurement sensor from Garmin(TM). The LIDAR-Lite v3HP istheideal optical ranging solution for drone， robot， or unmanned vehicle applications. Each sensor is housed in a durable， IPX7-rated housing and includes all the core features and user configurability of the popular LIDAR-Lite v3.The v3HP is very similar in function to that of the v3 but it can now sample faster at rates greater than 1kHz(where as the v3 is only capable of up to 500Hz). Another improvement is that this v3HP model is more power efficient with current consumption rates 40mA less than the v3(that's 65mA as opposed to 105mA while idle， and 85mA instead of 130mA while acquiring).Each LIDAR-Lite v3HP has a range of 1m to 40m and features an edge-emitting， 905nm(1.3 watts)， single-stripe laser transmitter， 8m Radian beam divergence， and an optical aperture of 12.5mm. This version of the LIDAR-Lite still operates at 5VDC(6V max)with a peak power of 1.3W and still possesses an accuracy of +/- 2.5cm at >2m. On top of everything else， the LIDAR-Lite is user-configurable， allowing adjustment between accuracy， operating range and measurement time and can be interfaced via I2C or PWM with the attached 200mm cable.Note：CLASS 1 LASER PRODUCT CLASSIFIED EN/IEC 60825-1 2014.

DescriptionThe SparkFun Inventor's Kit(SIK)for Arduino Uno is a great way to get started with programming and hardware interaction with the Arduino programming language. The SIK includes everything you need to complete five overarching projects consisting of 16 interconnected circuits that teach everything from blinking an LED to reading sensors. The culminating project is your very own autonomous robot! No previous programming or electronics experience is required to use this kit.The online guide contains step-by-step instructions with circuit diagrams and hookup tables for building each project and circuit with the included parts. Full example code is provided， new concepts and components are explained at point of use， and troubleshooting tips offer assistance if something goes wrong.The kit does not require any soldering and is recommended for beginners ages 10 and up who are looking for an Arduino starter kit. For SIK version 4.1 we took an entirely different approach to teaching embedded electronics. In previous versions of the SIK， each circuit focused on introducing a new piece of technology. With SIK v4.1， components are introduced in the context of the circuit you are building， and each circuit builds upon the last， leading up to a project that incorporates all of the components and concepts introduced throughout the guide. With new parts and a completely new strategy， even if you've used the SIK before， you're in for a brand-new experience!This version of the SIK replaces the SparkFun RedBoard Qwiic with the Arduino Uno(SMD version)and comes without the SIK guidebook and carrying case. With these components being swapped and removed， we were able to reduce the overall size and weight of the kit， making shipping cheaper and easier for anyone ordering internationally.Note：As stated above， this SIK does NOT include a carrying case or print guidebook.Get Started With the SparkFun Inventor's Kit v4.1 Experiment GuideExamplesProject 1：LightCircuit 1A：Blinking an LEDCircuit 1B：PotentiometerCircuit 1C：PhotoresistorCircuit 1D：RGB Night-LightProject 2：SoundCircuit 2A：BuzzerCircuit 2B：Digital TrumpetCircuit 2C："Simon Says" GameProject 3：MotionCircuit 3A：Servo MotorsCircuit 3B：Distance SensorCircuit 3C：Motion AlarmProject 4：DisplayCircuit 4A：LCD "Hello， World!"Circuit 4B：Temperature SensorCircuit 4C："DIY Who Am I?"

DescriptionPoke Home Connectors have been featured on a number of our boards over the last few years by providing a simple screw-terminal-type connector for easy wire connection purposes. Similar to screw terminals， Poke Home Connectors grasp a wire entered into the receiving area of the pin-out by pressing down on the small plastic strip at the end of the housing. Doing so raises the internal clamp and， upon release of the button secures the wire in place without any soldering required.Poke Home Connectors work better in environments with a lot of vibrations(i.e. automotive applications)or when a wire is expanding or contracting due to temperature cycling. Additionally， the tension in the connector is automatically adjusted to the wire gauge(assuming it is within the accepted wire thickness)as opposed to variances in tension when a user tightens the screw terminal.

DescriptionDo you want to replace a slider or a button on your art project or science experiment with a more interesting interface? This Capacitive Touch Slider is a "Qwiic" and easy way to add capacitive touch to your next project. With the board's built in touch pads， you can immediately start playing with the touch capabilities as three unique touch inputs or as a slider. You can also enable a touch input to act as a power button， customize the sensitivity for your own touch pads， and play with the interrupt alert LED. Utilizing our Qwiic system， no soldering is required to connect it to the rest of your system. However， we have broken out 0.1"-spaced pins in case you prefer to use a breadboard or create your own touch pads.On the front of the board， there is an arrow shape which contains three separate capacitive touch pads. We also broke out the capacitive touch sensor lines as plated through-holes on the top of the board. You can use these pins to connect to your own capacitive touch pads. The CS1 pin connects to the left pad， the CS2 pin connects to the middle pad， and the CS3 pin connects to the right pad.NOTE：The I2C address of the CAP1203 is 0x28 and is hardware defined. A multiplexer/Mux is required to communicate to multiple CAP1203 sensors on a single bus. If you need to use more than one CAP1203 sensor consider using the Qwiic Mux Breakout.The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.

DescriptionThe SparkFun Pulse Oximeter and Heart Rate Sensor is an I2C based biometric sensor， utilizing two chips from Maxim Integrated：the MAX32664 Biometric Sensor Hub and the MAX30101 Pulse Oximetry and Heart Rate Module. While the latter does all the sensing， the former is an incredibly small and fast Cortex M4 processor that handles all of the algorithmic calculations， digital filtering， pressure/position compensation， advanced R-wave detection， and automatic gain control. We've provided a Qwiic connector to easily connect to the I2C data lines but you will also need to connect to two additional lines. This board is very small， measuring at 1in×0.5in(25.4mm×12.7mm)， which means it will fit nicely on your finger without all the bulk.The MAX30101 does all the sensing by utilizing its internal LEDs to bounce light off the arteries and arterioles in your finger's subcutaneous layer and sensing how much light is absorbed with its photodetectors. This is known as photoplethysmography. This data is passed onto and analyzed by the MAX32664 which applies its algorithms to determine heart rate and blood oxygen saturation(SpO2). SpO2 results are reported as the percentage of hemoglobin that is saturated with oxygen. It also provides useful information such as the sensor's confidence in its reporting as well as a handy finger detection data point. To get the most out of the sensor we've written an Arduino Library to make it easy to adjust all the possible configurations.The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.

DescriptionThe SparkFun ZOE-M8Q GPS Breakout is a high accuracy， miniaturized， GPS board that is perfect for applications that don't possess a lot of space. The on-board ZOE-M8Q is a 72-channel GNSS receiver， meaning it can receive signals from the GPS， GLONASS， BeiDou， and Galileo constellations. This increases precision and decreases lock time and thanks to the onboard rechargable battery you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally， this u-blox receiver supports I2C(u-blox calls this Display Data Channel)which made it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports.

DescriptionThe SparkFun RTK Surveyor is an easy to use GNSS receiver for centimeter-level positioning. Perfect for surveying， this preprogrammed device can also be used for autonomous driving， navigation， asset tracking and any other application where there is a clear view of the sky. The RTK Surveyor can also be used as a base station. With the flick of a switch， two RTK Surveyors can be used to create an RTK system capable of 14mm horizontal positional accuracy. The built-in Bluetooth(R)connection via an ESP32 WROOM enables the user to use the RTK Surveyor with their choice of GIS application on a phone or tablet. The built in battery allows field use for up to four hours and is compatible with common USB battery banks.This device can be used in four modes：GNSS Positioning(～30cm accuracy)GNSS Positioning with RTK(1.4cm accuracy)GNSS Base StationGNSS Base Station NTRIP ServerIn Position mode the device receives L1/L2 signals from a user-provided antenna and the high-grade GNSS receiver provides lat/long and altitude with accuracies around 300mm.In Positioning with RTK mode the device receives L1/L2 signals from the antenna and correction data from a base station. The correction data can be obtained from a cellular link to online correction sources or over a radio link to a 2nd RTK Surveyor setup as a base station.In Base Station mode the device is mounted to a temporary position(like a tripod)and begins transmitting correction data over a radio or internet connection. A base is often used in conjunction with a second unit set to 'Positioning with RTK' to obtain the 14mm relative accuracy.In Base Station NTRIP Server mode the device is mounted to a semi or permanently fixed position(like a roof)and connects over WiFi to transmit the correction data to a NTRIP caster so that any rover can access the correction data over a cellular or internet connection. This type of base is a very easy way to setup a very precise absolute correction source.Two cables are provided with the RTK Surveyor allowing a user to plug on our easy to use Serial Telemetry Radios or their own radio link. If a local correction source is within 10km， a user can also use their phone to provide correction data over the Bluetooth(R)link(no external radio needed!).Note：The SparkFun RTK Surveyor is just the enclosed device and does NOT include an antenna， serial telemetry radio， or associated mounting pieces.

DescriptionA lot of the time you just need to add more analog inputs to solve a problem. It happens. The SparkFun Qwiic 12 Bit ADC can provide four channels of I2C controlled ADC input to your Qwiic enabled project. These channels can be used as single-ended inputs， or in pairs for differential inputs. What makes this even more powerful is that it has a programmable gain amplifier that lets you "zoom in" on a very small change in analog voltage(but will still effect your input range and resolution). Utilizing our handy Qwiic system， no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.The ADS1015 uses its own internal voltage reference for measurements， but a ground and 3.3V reference are also available on the pin outs for users. This ADC board includes screw pin terminals on the four channels of input， allowing for solderless connection to voltage sources in your setup. It also has an address jumper that lets you choose one of four unique addresses(0x48， 0x49， 0x4A， 0x4B). With this， you can connect up to four of these on the same I2C bus and have sixteen channels of ADC. The maximum resolution of the converter is 12-bits in differential mode and 11-bits for single-ended inputs. Step sizes range from 125μV per count to 3mV per count depending on the full-scale range(FSR)setting.We have included an onboard 10K trimpot connected to channel A3. This is handy for initial setup testing and can be used as a simple variable input to your project. But don't worry， we added an isolation jumper so you can use channel A3 however you'd like.Note：The I2C address of the ADS1015 is 0x48 and is jumper selectable to 0x49， 0x4A， 0x4B. A multiplexer/Mux is required to communicate to multiple ADS1015 sensors on a single bus.

DescriptionGet with the times， already! This SparkFun Real Time Clock(RTC)Module is a Qwiic-enabled breakout board for the RV-1805 chipset. The RTC is ultra-low power(running at only about 22nA in its lowest power setting)so it can use a supercapacitor for backup power instead of a normal battery. This means you get plenty of charge and discharge cycles without any degradation to the "battery." To make it even easier to get your readings， all communication is enacted exclusively via I2C， utilizing our handy Qwiic system so no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.This RTC module's built in RV-1805 has not one， but two internal oscillators：a 32.768kHz tuning fork crystal and a low power RC based oscillator and can automatically switch between the two using the more precise crystal to correct the RC oscillator every few minutes. This feature allows the module to maintain a very accurate date and time with the worst case being +/- about three minutes over a year. The RV-1805 also has a built in trickle charger so as soon as the RTC is connected to power the it will be fully charged in under 10 minutes and has the ability to switch power to other systems allowing it to directly turn on or off a power hungry device such as a microcontroller or RF engine.There is also the option to add a battery to the board if the supercapacitor just isn't going keep your project powered long enough(keep in mind， the supercap can hypothetically make the board keep time for around 35 days)， you can solder on an external battery. That means you can let board sit with no power or connection to the outside world and the current hour/minute/second/date will be maintained.Note：The I2C address of the RV-1805 is 0x69 and is hardware defined. A multiplexer/Mux is required to communicate to multiple RV-1805 sensors on a single bus.

The SparkFun Qwiic Keypad comes fully assembled and makes the development process for adding 12 button keypad easy. No voltage translation or figuring out which I2C pin is SDA or SCL， just plug and go! Utilizing our handy Qwiic system， no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use breadboard.Each of the keypad's 12 buttons has been labeled 1， 2， 3， 4， 5， 6， 7， 8， 9， 0， *， and and has been formatted to into the same layout as telephone keypad with each keypress resistance ranging between 10 and 150 Ohms. The Qwiic Keypad reads and stores the last 15 button presses in First-In， First-Out(FIFO)stack， so you don't need to constantly poll the keypad from your microcontroller. This information， then， is accessible through the Qwiic interface. The SparkFun Qwiic Keypad even has software configurable I2C address so you can have multiple I2C devices on the same bus.NOTE：The I2C address of the Qwiic Keypad is 0x4B and is jumper selectable to 0x4A(software-configurable to any address). multiplexer/Mux is required to communicate to multiple Qwiic Keypad sensors on single bus.

DescriptionThe SparkFun I2S Audio Breakout board uses the MAX98357A digital to analog converter(DAC)， which converts I2S(not be confused with I2C)audio to an analog signal to drive speakers. The I2S Audio Breakout converts the digital audio signals using the I2S standard to an analog signal and amplifies the signal using a class D amplifier which can deliver up to 3.2W of power into a 4Ω load. The board can be configured to output only the left channel audio， right channel， or both.The SparkFun I2S Audio Breakout board is fairly simple， requiring only a few pin connections to get it up and working. By default the board is configured in "mono" operation， meaning the left and right signals are combined together to drive a single speaker. If you want a separate speaker for the left and right audio channels you'll need to cut the mono jumper. In addition to being able to select the audio channel output， the gain can also be configured in a few ways. The gain of the amplifier can be configured from as low as +3dB to as high as +15dB. While the channel selection can be configured on board， the gain however is controlled externally using the gain pin. By default， the board is configured for +9dB， but can be easily changed!Get Started with the SparkFun I2S Audio Breakout GuideFeaturesSupply Voltage Range：2.5V - 5.5V.Output Power：3.2W into 4Ω at 5V.Output Channel Selection：Left， Right， or Left/2 + Right/2(Default).Sample Rate：8kHz - 96kHz.Sample Resolution：16/32 bit.Quiescent Current：2.4mA.Filterless Class D OutputsNo MCLK RequiredClick and Pop ReductionShort-Circuit and Thermal Protection.

DescriptionThe SparkFun Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight.
