Grbl_ESP32 Development Board Version 3.1

This is a quick blog post to document version 3.1. This is for sale at Tindie, but you can make your own via these files.

What is new

  • Integrated SD card socket: This no longer uses a plug in module.
  • Integrated 5V 3A DC power supply.: The previous plug in module used the same parts, but was adjustable. The adjustment was very sensitive and prone to drifting a little.
