PiCubed: common questions

What microcontroller does the PiCubed use?

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

How big is the PiCubed PCB?

The PiCubed has 2 copper layers and is 1.6 mm thick.

How many components are on the PiCubed?

369 components, from 103 distinct parts. The full bill of materials is listed on this page.

Where can I download the PiCubed design files?

From the NeilKhera/PiCubed repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PiCubed design in my own project?

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

Can I test firmware for the PiCubed 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.
