From the project

MKS CANable V2.0 based isolated USB-CAN interface

This repository contains the design file for an isolated USB-CAN interface PCB. It is based upon the MKS CANable V2.0 and is compatible with the CANable V2.0 firmware. It connects to the CAN bus via RJ45 connectors which can be configured with whatever pinout you require!

Firmware compatible with CANable V2.0 firmware - can be flashed & updated with the CANable 2.0 web updater. RJ45 pinout configured via solder-able jumpers. Galvanic isolation between CAN port and USB. Two RJ45 connector in parallel allows for inserting inline on bus - all eight signal are passed through. DIP switch to…

CANchovy: common questions

What microcontroller does the CANchovy use?

The CANchovy is built around the STM32G431C8T6, from the STM32 family.

How big is the CANchovy PCB?

The CANchovy measures 75 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the CANchovy?

59 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the CANchovy design files?

From the fred314159265/CANchovy repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the CANchovy design in my own project?

The repository has no license, so all rights stay with fred314159265. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the CANchovy without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
