The KiCad project lives in the rosmo-robot/CM4-Beagleboard repository on GitHub; these links point at the commit this page was built from.

CM4-Beagleboard: common questions

What microcontroller does the CM4-Beagleboard use?

The CM4-Beagleboard is built around the ComputeModule4, from the Raspberry Pi family.

How big is the CM4-Beagleboard PCB?

The CM4-Beagleboard measures 83.8 × 20.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CM4-Beagleboard?

29 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the CM4-Beagleboard design files?

From the rosmo-robot/CM4-Beagleboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the CM4-Beagleboard design in my own project?

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

Can I test firmware for the CM4-Beagleboard 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.
