PLC EVSE

For use together with pyPLC.

This is a KiCad 8 project. Only the schematic, no board.

BOM

  • C1, C2, C3: elcap, 100µF, 25V
  • C20: ceramic, 1nF (something between 1nF and 2.2nF is fine)
  • U1: op-amp LF355
  • U2, U3: isolated DCDC converter, 5V to 12V, 1W, e.g. B0512S-1WR3
  • R1: 1k
  • R2: 270ohm
  • R5: 56k
  • R6: 100k
  • R7: 220k
  • R8, R9: 120k (does not really matter, also 100k would be fine)
  • R20: 180ohm (does not really matter. Something between 100ohm and 330ohm.)
  • D1, D2: LEDs WS2812B. Also one would be sufficient.
  • RV1: potentiometer e.g. 10k linear (also 1k or 22k would be fine)
  • A1: Arduino Nano
  • Prototyping board 100mm x 106mm
  • Housing 3D printed, FreeCad mini-evse-housing.FCStd, or step: mini-evse-housing.step
  • For power supply: USB A cable, cutted and soldered to the board.
