Pi CM4 16: common questions

What microcontroller does the Pi CM4 16 use?

The Pi CM4 16 is built around the 2x DF40C-100DS-0.4V, from the Raspberry Pi family.

How big is the Pi CM4 16 PCB?

The Pi CM4 16 measures 142.1 × 106 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pi CM4 16?

113 components, from 66 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 Pi CM4 16 design files?

From the computergeek1507/PB_16 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 Pi CM4 16 design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which computergeek1507 chose for the repository.

Can I test firmware for the Pi CM4 16 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.
