6 open source boards using the PESD2CAN
Real designs built with the PESD2CAN, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

How designs wire the PESD2CAN
Read from the KiCad layouts of 6 open source designs, one per repository: what each pin of the PESD2CAN connects to, and the resistors, capacitors and other passives placed on it.
- The K pins have a series resistor on 5 of 6 designs, most often 10 kΩ (then 120 Ω).
- The A pin is tied to GND on 6 of 6 designs.
| Pin | Connected to | Parts on the pin |
|---|---|---|
| Kpin 1, 2 | Connected to: SN65HVD230 100%, a connector 100% |
|
| Apin 3 | Connected to: GND 100% | — |
Connections count pins, parts count designs; values in brackets are how many parts had that value. Designs read include Spha btni hardware by sillevl, Spha btnn hardware by sillevl, Spha btnu hardware by sillevl and Spha gateway hardware by sillevl.
