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.

DescriptionThe great thing about open source is that while SparkFun has designed our own MicroMod carrier boards， that does not stop you from creating your very own MicroMod carrier board. The MicroMod DIY Carrier Kit includes five M.2 connectors(4.2mm height)， screws， and standoffs so that you can get all the special parts you may need to make your own carrier board.MicroMod uses the common M.2 connector. This is the same connector found on modern motherboards and laptops. There are various locations for the plastic 'key' on the M.2 connector to prevent a user from inserting an incompatible device. The MicroMod standard uses the 'E' key and further modifies the M.2 standard by moving the mounting screw 4mm to the side. The 'E' key is fairly common so a user could insert a M.2 compatible Wifi module but because the screw mount doesn't align， the user would not be able to secure an incompatible device into a MicroMod carrier board.MicroMod is a modular interface ecosystem that connects a microcontroller "processor board" to various "carrier board" peripherals. Utilizing the M.2 standard， the MicroMod standard is designed to easily swap out processors on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!

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. If you need to use more than one RV-1805 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. 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.Get Started with the RV-1805 Real Time Clock Module GuideFeaturesOperating Voltage(Startup)：1.6V - 3.6VOperating Voltage(Timekeeping)：1.5V - 3.6VOperating Temperature：-40℃ - 85℃Time Accuracy：±2.0 ppmCurrent Consumption：22nA(Typ.)I2C Address：0xD2Supercapacitor for Backup Power2x Internal Oscillators2x Qwiic Connectors

DescriptionThis MI：pro Protector Case for the BBC micro：bit has been designed to work with both the original micro：bit V1 and the micro：bit V2. These cases feature a four-layer construction style with ability to mount a 2xAAA battery pack to the back of the case while still providing access to all buttons and ports on the micro：bit. Though these cases do protect the micro：bit astoundingly well， the biggest benefit of using the MI：pro is to not accidentally short out the pads on the back of the micro：bit.Construction is simple， requiring only a small flathead screwdriver(at most)， and involves layering each plate on top of one another around the micro：bit and screwing it into place.

DescriptionThe SparkFun Load Sensor Combinator is a bare PCB that combines four load sensors into a standard four-wire Wheatstone bridge configuration. If you open up an electronic bathroom scale， you'll find a large rat's nest of wires. The Load Sensor Combinator was created to combine the 12 wires found in a bathroom scale into the standard four-wire Wheatstone bridge configuration.This version of the SparkFun Load Sensor Combinator features a few changes that you specifically asked for! We updated the silk on the breakout to read "C/+/-" instead of "R/W/B" and moved the temperature sensor connector away from the standoff hole.You can either use four individual load sensors or simply purchase an off-the-shelf bathroom scale and hack the combinator into it rather than trying to design a base to properly mount four load sensors.This board works great with our Load Cell Amplifier breakout board； the five pins on the edge of the combinator line up directly to the five pins on the amplifier.If your amplifier and supporting electronics are more than a few inches away from the scale， an RJ45 footprint is provided. The four Wheatstone pins(E+/E-/S+/S-)as well as the shield pin are connected to twisted pairs within a standard cheap Ethernet cable. This allows the amplifier board to be placed many feet away from the scale itself.The combinator board also includes a footprint for the DS18B20 one-wire temperature sensor. This allows the user to gather the temperature of the scale in case there is a large variance between the scale and the amplifier. These three pins are accessed through the RJ45 connection as well， allowing remote temperature readings to be gathered over one twisted pair Ethernet cable.NOTE：The SparkFun Load Sensor Combinator will only work with 3 wire load sensors， it is not compatible with 4 wire load cells.

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 Xcelite 8-in-1 Screwdriver Set provides eight high-quality bits in a single ergonomic tool. Each bit is easily accessible with a spring-loaded magnetic housing that holds the seven included bits you aren't currently using. Though the screwdriver set includes eight unique bits， the end of the shaft features a 0.25" hex driver that can fit most of your existing 1/4" bits. With a strong magnetic hold and no-roll handle design， this is one of the best all-in-one tools we have used!The shaft of this multiple-tip driver is made from a chrome-molybdenum vanadium steel that makes for great durability and longevity.

DescriptionSometimes referred to as "spade connectors，" these quick disconnects are really useful as power connectors in prototyping or in projects that are repeatedly assembled and disassembled. The shape of these connectors allows them to be used with a variety of retro game-cabinet buttons， as well as lights similar to the ones found in our Spectacle line.These Female Quick Disconnects are about 1/4" wide， come in packs of five， and can be affixed to a 16-14 AWG wire. Mating connectors can be found in the similar items section below.

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.

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 SparkFun Qwiic HAT for Raspberry Pi is the quickest and easiest way to enter into SparkFun's Qwiic ecosystem while still using that Raspberry Pi that you've come to know and love. The Qwiic HAT connects the I2C bus(GND， 3.3V， SDA and SCL)on your Raspberry Pi to an array of Qwiic connectors on the HAT. Since the Qwiic system allows for daisy chaining boards with different addresses， you can stack as many sensors as you'd like to create a tower of sensing power!The Qwiic Pi HAT has four Qwiic connect ports， all on the same I2C bus. In addition， many of the useful GPIO pins on the Raspberry Pi are broken out. This HAT is compatible with any Raspberry Pi that utilizes the standard 2x20 GPIO header. It has been designed to sit to the side of the Pi， allowing it to work conveniently with a Pi Tin enclosure to connect boards to the Qwiic ports.Note：There is a small silk error that has reversed the SDA and SCL. This is simply a cosmetic mix-up and will not impact any function with this board.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.
