Introduction

TMC2130 is utilized for driving a bi-polar step motor in this example.
TMC2130 is a driver module with many functions. This guide explains how to connect TMC2130 directly with ESP8266 via SPI without a motherboard (e.g. MKS Gen L, RAMPS, Einsy Rambo etc.).

Used components:

  • TMC2130

  • ESP8266:

LoLin NodeMCU V3 4MB flash ESP8266 12E

Wiring

TMC2130 board must be modified for SPI communication mode according to manufacturer's instructions

A capacitor in between Vmotor and GND is recommended (here 220µF was used)
