CAN-USB-dongle: common questions

What microcontroller does the CAN-USB-dongle use?

The CAN-USB-dongle is built around the STM32F302C8T6, from the STM32 family.

How big is the CAN-USB-dongle PCB?

The CAN-USB-dongle measures 45 × 27 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CAN-USB-dongle?

52 components, from 25 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the CAN-USB-dongle design files?

From the cvra/CAN-USB-dongle repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the CAN-USB-dongle design in my own project?

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

Can I test firmware for the CAN-USB-dongle 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.
