。Description。The SparkFun Wireless Joystick Kit provides an easy way to control your next XBee project. Before the wireless joystick, radio-controlled projects used hobby RC transmitters, the same ones used for RC cars, boats and planes. The problem with these transmitters is that many aren't customizable, and the ones that are tend to be too expensive for many of us. The Wireless Joystick Kit offers a custom wireless solution for those who want to control their project their own way.。Equipped with the increasingly popular SAMD21 onboard, all you need is to assemble the SparkFun Wireless Joystick into the configuration you want and add your own XBee and lithium ion battery into the provided sockets. The Wireless Joystick Kit can be assembled into a configuration that utilizes dual joysticks for better RC steering robots(like tanks)or a single joystick configuration with four 12mm momentary pushbuttons(a setup similar to what older game consoles used). We have provided a full Hookup Guide that gives assembly instructions, as well as a tank-steering motor controller tutorial to help get you started!。Please be aware that the SparkFun Wireless Joystick Kit is。NOT supported on Windows 7/8。due to a lack of support drivers for those specific OS's.。Note:This kit will need to be assembled before use, so a beginner's knowledge of soldering will be required. Additionally, in an effort to keep shipping rates down and make this kit available to people throughout the world without delay, there is no XBee or lithium ion battery included.。Get Started with the Wireless Joystick Kit Guide

。Description。The SparkFun Continuous Rotation(CR)Servo Trigger is a small robotics board that simplifies the control of hobby RC servo motors. When an external switch or logic signal changes state, the CR Servo Trigger is able to tell an attached servo motor to move from position A to position B. To use the CR Servo Trigger, you simply connect a hobby servo and a switch, then use the on-board potentiometers to adjust the start/stop positions and the transition time. You can use a hobby servo in your projects without having to do any programming!。When we introduced the original Servo Trigger, we mentioned that it could be reprogrammed to be more useful with continuous rotation servo motors. But reprogramming the firmware is somewhat tedious, and users asked for a Servo Trigger preprogrammed with the continuous rotation logic. With this little board you will be provided an easy way to deploy continuous rotation servos into your projects!。The heart of the CR Servo Trigger is an Atmel ATtiny84 microcontroller, running a small program that implements the servo control features designed for continuous rotation servos. On board each of these CR Servo Triggers you will find three potentiometers:"A" sets the position the servo sits in while the switch is open, "B" sets the position the servo moves to when the switch is closed, and "T" sets the time it takes to get from A to B and back.。Compared with a servo motor, the CR Servo Trigger board draws very little current, roughly 5mA at 5V. Be sure to note that if you're using the CR Servo Trigger to control your motor, the absolute maximum supply voltage that should be applied is 5.5 VDC. Additionally, the SparkFun CR Servo Trigger is designed to make it easy to daisy chain boards - you can simply connect the VCC and GND pads on adjacent boards to each other.。Note:This idea originally came from our friend in the Oakland area, CTP. If you see him, please give him a high-five for us.。SparkFun CR Servo Trigger Hookup Guide。Features。Recommended Voltage:5VDC。Max Voltage:5.5VDC。Current Draw:5mA。Control Continuous Rotation Servos。Three Control Settings。A - sets the position the servo sits in while the switch is open。B - sets the position the servo moves to when the switch is closed。C - sets the time it takes to get from A to B and back。Easy Control with Potentiometers。Configurable Input Polarity。Configurable Response Mode。Compatible with Analog Servos。ISP Header Pins Available for Reprogram

Description。This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit(configurable)temperature readings over a 1-Wire interface, so that only one wire(and ground)needs to be connected from a central microprocessor. Power for reading, writing, and performing temperature conversions can be derived from the data line itself with no need for an external power source.。Because each DS18B20 contains a unique silicon serial number, multiple DS18B20s can exist on the same 1-Wire bus. This allows for placing temperature sensors in many different places. Applications where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings, equipment or machinery, and process monitoring and control.。Note:The pinout for this sensor is as follows:RED=Vcc BLACK=GND WHITE=SIG。Features。3.0-5.5V input voltage。-55℃ to +125℃ temperature range。±0.5℃ accuracy from -10℃ to +85℃。Waterproof。1 Wire interface。Probe is 7mm in diameter and roughly 26mm long. Overall length(including wire)is 6 feet.。Thermometer resolution is programmable from 9 to 12 bits.。Electrical performance:no flicker or breakdown within AC 1200V/1S ,within DC 500V theinsulation resistance shall be greater than 100MΩ

Description。The SparkFun RTK Express is an easy to use GNSS receiver for centimeter-level positioning. Perfect for surveying, 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 can also be used as a base station. With the press of a button, two RTK Expresses 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 Express 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. The RTK Express is built upon the same ZED-F9P u-blox receiver as the original RTK Surveyor so you can expect the same incredible performance and rich feature set. The embedded display allows for immediate feedback of horizontal positional accuracy, satellites in view, logging status, survey-in 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.。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 second RTK Surveyor/Express 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. The RTK Surveyor and RTK Express are interchangeable as a Base Station; an RTK Surveyor can be a base for an RTK Express and vice versa.。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 set up a very precise absolute correction source.。Two cables are provided with the RTK Express allowing a user to plug in 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 Express 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 Express 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。4MB 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 1300mAh with 500mA charging。Radio Port:3.3V TTL Serial(57600bps RTCM TX/RX)。Data Port:3.3V TTL Serial(115200bps NMEA)。Embedded OLED Display for available satellites, data logging, and more.。Push button controls。Weight:162g(entire device including battery)。Dimensions:132mm×101mm×32mm(5.2in×3.9in×1.2in)。1x Qwiic Connector。Changes:This version(which replaces SPX-18019)uses a reinforced edge mount SMA connector for better resiliency when a fixed 'stub' antenna is used.
