From the project

An ESP32/TMC2130 based 2 axis controller designed for pen plotters

Released under an MIT licence, no warranty implied or given, use at own risk etc etc.

This is a two axis stepper controller based on the ESP32 and TMC2130 stepper drivers. It is intended to be used with drawing machines and plotters.

See https://github.com/MarkJB/TMC429DaughterboardforESP32Plotter_Controller for the TMC429 (Hardware stepper driver contoller) daughter board for this board (plugs into the two stepper motor driver sockets and provides an extra axis and hardware acceleration control.
