About the SwitchboardSMD PCB

SwitchboardSMD is an open source PCB design by deltaphi, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 66 × 33 mm, with 42 components from 10 distinct parts.

Other key parts include the 4044 and 4014. By type, the board carries 19 resistors, 9 capacitors, 8 switches, 3 ICs, 2 connectors and 1 transistor.

From the project

Sketch for a Switchboard talking the CAN CS2 protocol based on the ESP32 NodeMCU-Board

This project is built using PlatformIO. It makes use of some features that may not be easily portable to other Arduino-supported MCUs.

This project makes use of several libraries. Versioned links to those libraries are available as git submodules. Note that for seom libraries, using forks from the same source as this project may be required.

Note that the CAN driver from the lib directory must not be present when you want to compile using the ESP32-IDF driver. Otherwise, the Controller will just attempt to sit there without sending queued messages or receiving any messages transmitted on…
