Canbus adapter: common questions

What microcontroller does the Canbus adapter use?

The Canbus adapter is built around the RP2040, from the RP2040/RP2350 family.

How big is the Canbus adapter PCB?

The Canbus adapter measures 100 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Canbus adapter?

77 components, from 36 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 Canbus adapter design files?

From the adeboni/laser-projector repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Canbus adapter design in my own project?

Yes, under the terms of its GPL-3.0 license, which adeboni chose for the repository.

Can I test firmware for the Canbus adapter without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
