Description。This 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.

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.

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 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 Station。GNSS Base Station NTRIP Server。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.。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. These items will need to be purchased separately from the Hookup Accessories below.。Get Started With the SparkFun RTK Surveyor Guide。Features。GNSS Receiver：ZED-F9P。Concurrent reception of GPS， GLONASS， Galileo and BeiDou。Receives both L1C/A and L2C bands。Current：68mA - 130mA(varies with constellations and tracking state)。Time to First Fix：25s(cold)， 2s(hot)。Max Navigation Rate：PVT(basic location over UBX binary protocol)- 25Hz。RTK - 20Hz。Raw - 25Hz。Horizontal Position Accuracy：2.5m without RTK。0.010m with RTK。Max Altitude：50km(31 miles)。Max Velocity：500m/s(1118mph)。Bluetooth(R)Transceiver：ESP32 WROOM。Xtensa(R)dual-core 32-bit LX6 microprocessor。Up to 240MHz clock frequency。16MB of flash storage。520kB internal SRAM。Integrated 802.11 BGN WiFi transceiver。Integrated dual-mode Bluetooth(R)(classic and BLE)。Hardware accelerated encryption(AES， SHA2， ECC， RSA-4096)。2.5 μA deep sleep current。Overall Device。Internal Battery：LiPo 1000mAh with 500mA charging。Radio Port：3.3V TTL Serial(57600bps RTCM TX/RX)。Data Port：3.3V TTL Serial(115200bps NMEA)。Weight：132g(entire device including battery)。Dimensions：118mm×79mm×30mm(4.7in×3.1in×1.2in)。1x Qwiic Connector。1x microSD Socket for optional logging。Changes：This version(which replaces SPX-17369)uses a reinforced edge mount SMA connector for better resiliency when a fixed 'stub' antenna is used.
