What a cutie pie! Or is it... a QT Py? This diminutive dev board comes with our favourite little chip, the SAMD21 (as made famous in our GEMMA M0 and Trinket M0 boards).
This time it comes withour favourite connector - the STEMMA QT, a chainable I2C port that can be used withany of our STEMMA QT sensors and accessories.
OLEDs!Inertial Measurement Units!Sensors a-plenty. All plug-and-play thanks to the innovative chainable design:SparkFun Qwiic-compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! Just plug in a compatible cable and attach it to your MCU of choice, and you’re ready to load up some software and measure some light.
Pinout and shape areSeeed Xiaocompatible, with castellated pads so you can solder it flat to a PCB. In addition to the QT connector, we also added anRGB NeoPixel(with a controllable power pin to allow for ultra-low-power usage),and a reset button(great for restarting your program or entering the bootloader)
Runs Arduino like a dream, and can be used for basic CircuitPython projects. For more advanced usage like data logging or file storage, solder a SOIC SPI flash chip onto the bottom pads,
