Still in early development, stepper drivers are untested as of 23/01/2025

Quite a powerful microcontroller that you can use on literally anything you like! There is an RP2040 MCU at its core, connected to a pair of TMC2209 silent stepper drivers. Tons of I/O, including 2 connectors for SPI with separate CS pin for each, broken out i2c, 2 Qwiic connectors, 2 ports for stepper motors, 2 switch channels, 2 servo channels, 2 potentiometer channels, and a USB-C port. There is also a barrel jack usable with a 12v or 24v power supply, with a switch alongside it to determine whether or not the stepper motors are driven off the 5v USB power or the barrel jack power. Optionally, you may also purchase the board with an integrated BMI088 IMU and BME280 barometer. 

(Due to a surprising lack of Qwiic connectors currently in existence, some boards are sold without them at a reduced cost.)
