Description。The SparkFun RTK Express Plus is an easy to use GNSS receiver for centimeter-level positioning. Perfect for surveying， autonomous vehicles， logging， and all types of post processing， 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 Express Plus adds an internal IMU to combine real-time GNSS tracking with advanced sensor fusion. The result is accurate positioning even when GNSS is lost in tunnels， parking garages， etc. Out of the box an RTK Express Plus can be used with a correction source 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 Express Plus with their choice of GIS application on a phone or tablet. The built in battery allows for over five hours of field use and is compatible with common USB battery banks.。We took all the lessons from the RTK Surveyor and built the RTK Express Plus. The RTK Express Plus is built upon the ZED-F9R u-blox receiver which uses the same F9 engine as all our RTK products but couples it with a built-in IMU. The embedded display allows for immediate feedback of horizontal positional accuracy， satellites in view， logging status， sensor fusion status， battery level， Bluetooth(R)MAC， etc. The rocker switches found on the original have been replaced by keypad buttons. We increased the battery to 1300mAh for a longer run time. The internal switches have been replaced by a digital mux allowing for some really exciting applications including event triangulation. More ESD protection was added to protect the RF path， and we even threw in an accelerometer for digital leveling in the field. Please note u-blox's sensor fusion algorithms are designed specifically for vehicles and will not aid in the accuracy of normal surveying.。This device can be used in two modes：GNSS Positioning(～30cm accuracy)。GNSS Positioning with RTK(1.4cm accuracy)。In 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. If enabled in automotive applications， the internal IMU augments the position information when GNSS reception is degraded.。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 RTK Surveyor/Express setup as a base station.

Description。The SparkFun MicroMod Environmental Function Board adds additional sensing options to the MicroMod Processor Boards. This Function Board includes three sensors to monitor air quality(SGP40)， humidity temperature(SHTC3)， and CO2 concentrations(STC31)in your indoor environment. To make it even easier to use， all communication is over the MicroMod's I2C bus!。The SGP40 measures the quality of the air in your room or house. The SGP40 uses a metal oxide(MOx)sensor with a temperature controlled micro hotplate and provides a humidity-compensated volatile organic compound(VOC)based indoor air quality signal. Both the sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real world applications enabling a unique long term stability as well as low drift and device to device variation.。The SHTC3 is a highly accurate digital humidity and temperature sensor. The SHTC3 uses a capacitive humidity sensor with a relative humidity measurement range of 0 to 100% RH and bandgap temperature sensor with a temperature measurement range of -40℃ to 125℃. The SHTC3 builds on the success of their SHTC1 sensor with higher accuracy(±2% RH， ±0.2℃)than its predecessor， enabling greater flexibility.。The STC31 measures CO2 concentrations based on thermal conductivity and has two CO2 measurement ranges：0 to 25 vol%； and 0 to 100 vol%. The measurement repeatability is 0.2 vol%， with a stability of 0.025 vol% / ℃. The measurement accuracy depends on the measurement range：0.5 vol% + 3% measured value； 1 vol% + 3% measured value. Using measurements from the SHTC3， the STC31 is able to provide humidity-compensated measurements together with improved temperature compensation. The STC31 can compensate for atmospheric pressure too - which is handy if， like us， you're up in the mountains!。The outstanding performance of these three sensors is based on Sensirion's patented CMOSens(R)technology， which combines the sensor element， signal processing， and digital calibration on a small CMOS chip. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.。Utilizing our handy M.2 MicroMod connector， no soldering is required to connect it to your system. Simply match up the key on your processor and function board's beveled edge connector to their respective key on the M.2 connector， then secure them to the main board with screws. The MicroMod Environmental Function Board can then be read via the I2C port. The board is equipped with the AP2112 3.3V voltage regulator， I2C pull-up resistors， power LED， jumper to disable the LED， and jumpers for alternative STC31 addresses.。Note：A MicroMod Processor and Main Board are not included with this MicroMod Environmental Function Board. These boards will need to be purchased separately.。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 and function boards on the fly.

A multiplexer/Mux is required to communicate to multiple SHTC3 sensors on a single bus. The SHTC3 uses the same address as the Qwiic Mux(0x70). For advanced users that are using multiple SHTC3's with the Qwiic Mux， you will need to adjust the Qwiic Mux's default address.

Description。The SparkFun Artemis Development Kit is the latest board to be released around the SparkFun Artemis Module and it allows access to more software development features than previous Artemis based boards. This Kit includes the SparkFun Artemis DK board as well as the accessories(Himax camera USB-C cable)needed to get started right away. Recommended software used to program the Artemis DK are the Arduino IDE， Arm(R)Mbed(TM)OS(Studio and CLI)， and AmbiqSDK. An updated USB interface(MKL26Z128VFM4 Arm(R)Cortex(R)-M0+ MCU， from NXP)allows the Artemis Dev Kit to act as：Mass Storage Device(MSD)：Used to provide drag and drop programming to the Artemis Module.。Human Interface Device(HID)：Used for the debugging interface to the Artemis Module.。Communication Port(COM)：Used to provide a serial communication UART between the Artemis and the USB connection(PC).。The Artemis Module provides a Cortex(R)-M4F with BLE 5.0 running at 48MHz with an available 96MHz turbo mode and power as low as 6uA per MHz(less than 5mW). The SparkFun Artemis Module is fully FCC/IC/CE certified with 1M flash and 384k RAM you'll have plenty of room for your code. The flexibility of the Artemis module starts with our Arduino core. You can program and use the Artemis module just like you would an Uno or any other Arduino. Additional functionality stems from the ability of the Artemis Dev kit to run RTOS such as the Arm Mbed OS， or the AmbiqSDK.。Attached to the。"Qwiic"。I2C bus， we've added a LIS2DH12TR MEMS accelerometer(for things like gesture recogntion)， a digital MEMS microphone， and an edge camera connector for the Himax CMOS imaging camera to experiment with always-on voice commands， and image recognition with TensorFlow and machine learning.
