DescriptionThe SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward to use. The two large， exposed pads function as probes for the sensor， together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be， resulting in a lower resistance and a higher SIG out. This version of the Soil Moisture Sensor includes a 3-pin screw pin terminal pre-soldered to the board for easy wiring and setup.To get the SparkFun Soil Moisture Sensor functioning， all you will need is to connect the VCC and GND pins to your Arduino-based device(or compatible development board). You will receive a SIG out， which will depend on the amount of water in the soil. One commonly known issue with soil moisture senors is their short lifespan when exposed to a moist environment. To combat this， we've had the PCB coated in gold finishing(ENIG， or Electroless Nickel Immersion Gold).Note：Check the Hookup Guide below for assembly and weatherproofing instructions， as well as a simple example project that you can put together yourself!Get Started with the Soil Moisture Sensor Guide

DescriptionThe MAX31820 ambient temperature sensor provides 9-bit to 12-bit Celsius temperature measurements with ±0.5℃ accuracy over a +10℃ to +45℃ temperature range. Over its entire -55℃ to +125℃ operating range， the device has ±2.0℃ accuracy.The device communicates over a one-wire bus that， by definition， requires only one data line(and ground)for communication with a central microprocessor. In addition， the device can derive power directly from the data line， eliminating the need for an external power supply. Requiring so few pins enables the device to be placed in a 3-pin TO-92 package. The form factor of this package allows the device to be placed above the board and thus measure the ambient temperature of a system， as opposed to the board temperature that a surface-mount package would measure.Each MAX31820 has a unique 64-bit serial code， which allows multiple MAX31820 devices to function on the same one-wire bus. Therefore， it is simple to use one microprocessor to control many devices distributed over a large area.FeaturesUnique one-wire interface requires only one port pin for communicationEach device has a unique 64-bit serial code stored in onboard ROMMultidrop capability simplifies distributed temperature-sensing applicationsRequires no external componentsCan be powered from data line； 3.0V to 3.7V power-supply rangeMeasures temperatures from -55℃ to +125℃±0.5℃ accuracy from +10℃ to +45℃Thermometer resolution is user-selectable from 9 bits to 12 bitsConverts temperature to 12-bit digital word in 750ms(Max)User-definable nonvolatile(NV)alarm settingsAlarm search command identifies and addresses devices whose temperature is outside programmed limits(Temperature Alarm Condition)Available in 3-pin TO-92 packageTO-92 package allows measurement of ambient temperatureSoftware compatible with the DS1822 and DS18B20

DescriptionUSB-C is quickly becoming more and more prominent in the maker community because， let's be honest， who likes trying three times to insert USB into a port? This is a 16-pin， female， USB Type C connector that is commonly found in smart phones， laptops， and other newer electronics. Each USB-C connector will require PTH soldering to secure it to your board and SMD soldering to connect each of the 16 control pins.If you are looking for an easier way to hook up a USB-C connector to your project， we do offer a breakout with 0.1" spaced， breadboard friendly pins.

DescriptionAdd another eight pins to your microcontroller using a MCP23008 port expander. The MCP23008 uses two I2C pins which can be shared with other I2C devices， and in exchange gives you eight general purpose pins. You can set each of eight pins to be input， output， or input with a pullup. There's even the ability to get an interrupt via an external pin when any of the inputs change so you don't have to keep polling the chip.Use this chip from 2.7-5.5V(good for any 3.3V or 5V setup)， and you can sink/source up to 20mA from any of the I/O pins so this will work for LEDs and such. Team it up with a high-power MOSFET if you need more juice. DIP package means it will plug into any breadboard or perfboard.You can set the I2C address by tying the ADDR0-2 pins to power or ground， for up to eight unique addresses. That means eight chips can share a single I2C bus - that's 64 I/O pins!Features8-bit remote bidirectional I/O portHigh-speed I2C interface(MCP23008)Hardware address pinsConfigurable interrupt output pinConfigurable interrupt sourcePolarity Inversion register for input port data polarity config.External reset inputLow standby current：1 μA(max.)・ Operating voltage：1.8V to 5.5V @ -40℃ to +85℃ I2C @ 100 kHz SPI @ 5 MHz2.7V to 5.5V @ -40℃ to +85℃ I2C @ 400 kHz SPI @ 10 MHz4.5V to 5.5V @ -40℃ to +125℃ I2C @ 1.7 kHz SPI @ 10 MHz

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. If you need to use more than one ADS1015 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.

DescriptionWe all like to know the temperature， right? Well， with the SparkFun TMP102 Digital Temperature Sensor， we've made it just about as easy as it gets. Based on the original Digital Temperature Sensor Breakout TMP102， we've added Qwiic connectors to bring this board into our plug-and-play Qwiic Ecosystem and added an address jumper instead of breaking out the address pin. However， we still have broken out 0.1"-spaced pins in case you prefer to use breadboard.The TMP102 itself is an easy-to-use digital temperature sensor from Texas Instruments. While some temperature sensors use an analog voltage to represent the temperature， the TMP102 uses the I2C bus of the Arduino to communicate the temperature.The TMP102 is capable of reading temperatures to resolution of 0.0625℃， and is accurate up to 0.5℃. The breakout has built-in 4.7kΩ pull-up resistors for I2C communications and runs from 1.4V to 3.6V. I2C communication uses an open drain signaling， so there is no need to use level shifting.The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.

DescriptionKeypads are very handy input devices， but who wants to tie up seven GPIO pins， wire up handful of pull-up resistors， and write firmware that wastes valuable processing time scanning the keys for inputs? 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 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. 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.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 ZOE-M8Q：baud rates， update rates， geofencing， spoofing detection， external interrupts， SBAS/D-GPS， etc. All of this can be done within the SparkFun Arduino Library. We've also made sure to configure the UART pin grouping on the breakout to an industry standard to insure that it easily connects to a Serial Basic.The SparkFun ZOE-M8Q GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the ZOE-M8Q. This reduces the time-to-first fix from a cold start(～30s)to a hot start(～1s). The battery will maintain RTC and GNSS orbit data without being connected to power for up to five hours. Since the ZOE-M8Q is a tiny GPS receiver and to minimize its footprint， we've added a U.FL connector to allow the use of both large standard ceramic antennas as well as very small chip scale antennas.Note：The I2C address of the ZOE-M8Q is 0x42 and is software configurable. A multiplexer/Mux is required to communicate to multiple ZOE-M8Q sensors on a single bus.

DescriptionUSB C is quickly becoming more and more prominent in the maker community because， let's be honest， who likes trying three times to insert USB into a port? This FTDI cable is a USB C to Serial converter which allows for a simple way to connect TTL interface devices to USB. Each 26AWG cable is one meter in length with the USB C side protected by a 2in enclosure.The FTDI cable is designed around an RS232， which is housed in a USB C connector. The other side of the cable is terminated with a 0.1" pitch， 6-pin connector with the following pinout：RTS(Green)， RX(Yellow)， TX(Orange)， VCC 5V(Red)， CTS(Brown)， GND(Black). This FTDI to USB C Cable is also capable of handling high voltages up to 300V max.There are pros and cons to the FTDI Cable vs the FTDI Basic. The FTDI Basic has great LED indicators， but requires a Mini-B 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.

DescriptionThis is an evaluation board for the Silicon Laboratories Si4703 FM tuner chip. Beyond enabling you to tune in to FM radio stations， the Si4703 is also capable of detecting and processing both Radio Data Service(RDS)and Radio Broadcast Data Service(RBDS)information. The Si4703 even does a very good job of filtering and carrier detection. It also enables data such as the station ID and song name to be displayed to the user.Using this board， you will be able to pick up multiple stations just as well as with a standard FM radio. The board breaks out all major pins and makes it easy to incorporate this great chip into your next radio project. The power bus， the 3.3V and GND pins are broken out For communication. The breakout provides access to SDIO and SCLK for I2C communication while RST can be used for easy resetting. The SEN pin enables the user to change the mode of functionality of the IC. The last two pins broken out are GPIO1 and GPIO2 which can be used as general input/output pins， but also can be used for things like the RDS ready， seeking or tuning functions.Keep in mind， by plugging headphones into the 3.5mm audio jack， you effectively use the cable in your headphones as an antenna! Therefore， this board does not require an external antenna if using headphones or a 3.5mm audio cable longer than 3 feet.

DescriptionYour 5V system can wield great power with this big， beefy relay board. How does 10A on the NC contacts and 20A on the NO contacts at 220VAC sound? The SparkFun Beefcake Relay Control Kit contains all the parts you need to get your high-power load under control. Only minimal assembly is required!The heart of the board is sealed， SPDT 20A/10A Relay. The relay is controlled by 5V logic through transistor， and an LED tells you when the relay is closed. This is kit， so it comes as through-hole parts with assembly required， which makes for some nice soldering practice. Screw terminal connectors on either side of the board make it easy to incorporate into your project.There are some pretty beefy traces connecting the relay to the load pins， but the 3-pin terminals are only rated for 15A max! If you plan on connecting larger load， you'll need to solder directly to the board. As always with high current and voltage， play it safe and use your judgment when deciding how much of load you want to put on board -- in open airflow the PCB can handle the full 20A for few minutes at time， but in an enclosed area heat can build up.Note：Please keep in mind that this board is really meant for someone with experience and good knowledge of electricity. If you're uncomfortable soldering or dealing with high voltage， please check out the IoT Power Relay.

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.

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.

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 ATECC608A chip is capable of many cryptographic processes， including， but not limited to：Creating and securely storing unique asymmetric key pairs based on Elliptic Curve Cryptography(FIPS186-3).AES-128：Encrypt/Decrypt， Galois Field Multiply for GCMCreating and verifying 64-byte digital signatures(from 32-bytes of message data).Creating a shared secret key on a public channel via Elliptic Curve Diffie-Hellman Algorithm.SHA-256 HMAC Hash including off-chip context save/restoreInternal high quality FIPS random number generator.Embedded in the chip is a 10Kb EEPROM array that can be used for storing keys， certificates， data， consumption logging， and security configurations. Access to the sections of memory can then be restricted and the configuration locked to prevent changes. Each ATECC608A Breakout ships with a guaranteed unique 72-bit serial number and includes several security features to prevent physical attacks on the device itself， or logical attacks on the data transmitted between the device.A summary datasheet for the ATECC608A is available here. The full datasheet is under NDA with Microchip. You will need to contact them for access to the entire datasheet. Meanwhile， the ArduinoATECCX08 Library currently only supports the ATECC608A with SAMD21 Arduino boards.We do have much more support for the ATECC508A version of this chip. Please check out our ATECC508A Hookup Guide and Arduino Library(which includes six examples). This will get you familiar with the basics of elliptic curve cryptography and signing/verifying data with the ATECC508A version of the chip.Note：The I2C address of the ATECC608A is 0x60 and is software-configurable to any address. A multiplexer/Mux is required to communicate to multiple ATECC608A sensors at the default address when on a single bus. If you need to use more than one ATECC608A sensor at the default address， consider using the Qwiic Mux Breakout.Note：The ATECC608A can be only configured once before it isPERMANENTLYlocked. It is advisable that users purchase multiple boards in order to use other configurations and explore the advanced functions of the ATECC608A.Additionally， this boardIScapable of encrypting and decrypting data. However， to access these additional features， you will need to contact Microchip and sign an NDA contract to obtain the complete datasheet.It is recommended that an SparkFun RedBoard Turbo - SAMD21 Development Board is used with this product due to the buffer size required on the I2C bus.The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.FeaturesOperating Voltage：2.0V-5.5V(Default on Qwiic System：3.3V)Active Current Draw(for ATECC608A)：16 mASleep Current(for ATECC608A)：<150 nAGuaranteed Unique 72-bit Serial Number10 Kb EEPROM Memory for Keys， Certificates， and DataStorage for up to 16 Keys256-bit Key LengthInternal High-Quality FIPS Random Number Generator(RNG)Configurable I2C Address(7-bit)：0x60(Default)
