Description。Buttons are an easy and tactile way to interface with your project， but why would you want to deal with debouncing， polling， and wiring up pull-up resistors? The Qwiic Button with built-in green LED simplifies all of those nasty worries away into an easy to use I2C device! Utilizing our Qwiic Connect System， using the button is as simple as connecting cable and loading up some pre-written code!。If you need multiple buttons for your project， fear not! Each button has configurable I2C address， so you can daisy-chain multiple buttons over Qwiic and still address each one individually. We've got an example in our Arduino library that provides super-easy way to configure your Qwiic Button to whatever I2C address you desire. You can download the library through the Arduino library manager by searching 'SparkFun Qwiic Button' or you can get the GitHub repo as .zip file and install the library from there.。In addition to handling blinking and debouncing， the Qwiic Button has configurable interrupts that can be configured to activate upon button press or click. We've also taken the liberty of implementing FIFO queue onboard the Qwiic Button where it keeps an internal record of when the button was pressed. This means that code on your microcontroller need not waste valuable processing time checking the status of the button but instead can run small function whenever the button is pressed or clicked! For more information on interrupts check out our guide here!。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 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 SparkFun Qwiic Button Guide。Features。12mm Green LED Button rated for 50mA。Built in LED can be configured for your desired level of blinkiness!。Each button has configurable I2C address。Configurable interrupts check out our guide here!。FIFO queue。Don't like the color green?

Description。The SparkFun MAX31855K Thermocouple Breakout is a simple 14-bit resolution， SPI-compatible， serial interface thermocouple digitizer that makes reading a wide range of temperatures possible. A thermocouple works by taking two wires made of dissimilar metals， connecting them at the two ends， and making a temperature gradient between one end and the other(a 'hot' end and a 'cold' one). Once this is achieved， a voltage potential is formed and current flows. The SparkFun Thermocouple Breakout takes a standard Type-K thermocouple in one end， digitizes the temperature measured and sends that data out the other end via a SPI interface， thereby interpreting the data and translating it for you to read!。With the SparkFun Thermocouple Breakout， the thermocouple's hot junction can be read from -200℃ to +700℃ with an accuracy of ±2℃ while the cold junction， inside the MAX31855K， can only range from -20℃ to +85℃ while maintaining ±2℃ accuracy. The MAX31855K constantly measures the temperature of the cold junction using an internal temperature-sensing diode. The MAX31855K requires a power source from +3.0V to +3.6V(+3.0V nominal)and only draws 1.5mA maximum.。The Thermocouple Breakout is designed to accept a standard thermocouple connector， for convenience and compatibility with probes you may already own. These connectors aren't necessary， and you could solder a thermocouple directly into the through-holes labeled '+' and '-'. If you decide to solder the thermocouple directly to the breakout board， it is recommended that the thermocouple be mounted for strain relief to avoid breaking the thin wires. Notches for a zip-tie or wire wrapping have been provided in the PCB opposite the header for this purpose.。Features。14-bit Resolution。SPI-Compatible， Serial Interface。-200℃ to +700℃ Temperature Reading with ±2℃ Accuracy。3.0V to 3.6V(+3.0V nominal)Required。Accepts Type-K Thermocouple

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. If enabled in automotive applications， the internal IMU augments the position information when GNSS reception is degraded.。Two cables are provided with the RTK Express Plus allowing a user to plug in our easy to use Serial Telemetry Radios or their own radio link.
