Barduino_ESP32_board

Barduino

Barduino 2.0 from FabLab Barcelona is the control board of mini CNC called SPML Machine.

Board

Design files are possible to download from Barduino 2.0 site, but in my case the components, foot print and rayout are needed to be replaced by some reason.

  1. Foot print of ESP32 library is modified for milling by 1/64” endmil.

  2. Foot print of FTDI pins is replaced due to be placed on the board edge.

  3. Slide swich has two holes which is registration post

  4. Replace the Foot print of Resistor and capaciter from Fab.lbr
