Status as of 2020/1/15:
*Completed

== 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
Manufacturer: Big Tree Tech

* ESP8266:
LoLin NodeMCU V3 4MB flash ESP8266 12E 

More info on ESP8266:

== 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)
