About the IOBreakout PCB

IOBreakout is an open source PCB design by deltaphi, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 85.1 × 49.5 mm, with 45 components from 19 distinct parts.

By type, the board carries 22 resistors, 10 capacitors, 8 switches and 5 connectors.

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…
