Added schematic in KiCad format #28

Closed virxkane closed 10 months ago

virxkane commented 1 year ago

Added schematic in KiCad format (2 variants). Based on original scheme https://github.com/1a2m3/SPD-Reader-Writer/tree/master/schematic with some changes:

The PC817 optocoupler can also be replaced with two BSS138s, but this seemed impractical to me.

2 variants prepared:

  1. The folder 'contrib/schematic/kicad' can be used to order a PCB from any factory, zip archive with gerbers attached.
  2. The folder 'contrib/schematic/kicad_diy' can be used for DIY, a drawing for thermal transfer is attached. Can use only the bottom layer, in which case there are only 4 wire (jumpers) on the top layer.

The circuit is assembled according to the second variant and tested, it works.

Unintentionally closed while cleaning repo, trying to reopen so others can get inspired by your work.

Reopening didn't work. 😟

If you really need this, I can open new PR.

But it after a whole year... :)
