About the Can converter PCB

Can converter is an open source STM32 PCB design by bluesatunsw, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 40.6 × 17.2 mm, with 25 components from 18 distinct parts.

Its main chip is the STM32G0B1CBT, from the STM32 family. Other key parts include the TCAN1462V. By type, the board carries 8 capacitors, 8 resistors, 3 diodes, 2 ICs, 2 crystals and 1 connector.

From the project

This repo includes all software necessary to operate the Test Rover Platform that is being designed and developed in the 502 project.

USB CANFD Device, based on the upstream CandleLightFD project (STM32G4 variant)

A small USB-C device that allows for the reading of can signals from the rover.

The device uses 5V power from the USB-C port to power, with a buck converter for the 3.3V power on the board. The CAN signals are processed by the TCAN1462V transceiver. The transceiver is connected to the STM32 with data signals RXD, TXD and a standby input. The STM32 also interfaces with two LEDs to display the functionality of the device and actions it's currently performing. CAN signals are processed by the STM32 and sent to the…

Can converter: common questions

What microcontroller does the Can converter use?

The Can converter is built around the STM32G0B1CBT, from the STM32 family.

How big is the Can converter PCB?

The Can converter measures 40.6 × 17.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Can converter?

25 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Can converter design files?

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

Can I use the Can converter design in my own project?

Yes, under the terms of its Apache-2.0 license, which bluesatunsw chose for the repository.

Can I test firmware for the Can converter 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.
