Canbus controller: common questions

What microcontroller does the Canbus controller use?

The Canbus controller is built around the ComputeModule4, from the Raspberry Pi family.

How big is the Canbus controller PCB?

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

How many components are on the Canbus controller?

74 components, from 38 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 controller 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 controller 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 controller without the hardware?

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