。Description。USB 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.

Description。The MQ-2 is a smoke and combustible gas sensor from Winsen. It can detect flammable gas in a range of 300 - 10000ppm. It's most common use is domestic gas leakage alarms and detectors with a high sensitivity to propane and smoke. The sensing material is SNO2 for which the conductivity is lower in clean environments and higher when smoke or flammable gas is present. A simple circuit makes measuring this change in conductivity and turning it into data fairly straight-forward， but does require some calibration.。For easy Solderability； use our Gas Sensor Breakout Board.

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.

Description。This is the SparkFun RFM69 Breakout， a small piece of tech that breaks out all the pins available on the RFM69HCW module as well as making the transceiver easy to use. The RFM69HCW is an inexpensive and versatile radio module that operates in the unlicensed ISM(Industry， Science and Medicine)radio band. It's perfect for building inexpensive short-range wireless networks of sensors and actuators for home automation， citizen science and more.。This RFM69HCW operates on the 434MHz frequency and is capable of transmitting at up to 100mW and up to 300kbps， but you can change both of those values to fit your application. For example， you can maximize range by increasing the transmit power and reducing the data rate， or you can reduce both for short-range sensor networks that sip battery power. At full power and with simple wire antennas， we can get messages from one side of a large office building to the other through numerous internal walls. In open air you can reach 500 meters or more. With more complex antennas and modulation schemes， similar parts have successfully transmitted from space to the ground(by very smart amateur radio enthusiasts； your mileage may vary)!。The RFM69HCW uses an SPI(Serial Peripheral Interface)to communicate with a host microcontroller， and several good Arduino libraries are available. It supports up to 256 networks of 255 nodes per network， features AES encryption to keep your data private， and transmits data packets up to 66 bytes long.。SparkFun sells two versions of the RFM69HCW：a 915MHz version and this 434MHz version. Although the ISM band is license-free， the band itself is different in different areas. Very roughly， 915MHz is for use in the Americas， and the 434MHz version is for use in Europe， Asia and Africa. Check your local regulations for other areas.。Get Started with the RFM69HCW Hookup Guide。Features。Transmit power：-18dBm(0.016mW)to +20dBm(100mW)in 1dBm steps。Receive sensitivity：down to -120dBm at 1.2kbps。Modulation types：FSK GFSK MSK GMSK OOK。Bit rates(FSK)：1.2kbps to 300kbps。Voltage range：1.8V to 3.6V。Current consumption：0.1uA sleep， 1.25mA standby， 16mA receive， 130mA transmit(max)。Encryption：AES 128-bit(optional)。Packet buffer(FIFO)：66 bytes。0.8"×1.1"
