CM4Card: common questions

What microcontroller does the CM4Card use?

The CM4Card is built around the ComputeModule4-CM4, from the Raspberry Pi family.

How big is the CM4Card PCB?

The CM4Card measures 64.6 × 44 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the CM4Card?

54 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the CM4Card design files?

From the will127534/Miniature-CM4-Cluster repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the CM4Card design in my own project?

Yes, under the terms of its MIT license, which will127534 chose for the repository.

Can I test firmware for the CM4Card 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.
