About the CM5IO PCB

CM5IO is an open source Raspberry Pi PCB design by mindhashnl, published on GitHub. It is a 4-layer board measuring 160 × 90 mm, with 63 components from 42 distinct parts.

Its main chip is the ComputeModule5-CM5, from the Raspberry Pi family. Other key parts include the TPSM33625RDNR, 74HC595, TCA9416DDFR and TMUX1511RSVR. By type, the board carries 19 capacitors, 16 resistors, 13 connectors, 8 ICs, 3 diodes and 1 battery holder.

From the project

Yggdrasil is an open-source, modular hardware-in-the-loop (HIL) testing framework designed for continuous integration (CI/CD) of embedded systems. It allows developers to test firmware automatically on real microcontrollers (MCUs) at scale.

Yggdrasil is an open-source, modular hardware-in-the-loop (HIL) testing framework designed for continuous integration (CI/CD) of embedded systems. It allows developers to test firmware automatically on real microcontrollers (MCUs) at scale.

The physical architecture is designed to fit inside a standard 19-inch 3U server rack and consists of a primary control board, a multiplexing backplane, and hot-swappable target testing blades.

CM5IO: common questions

What microcontroller does the CM5IO use?

The CM5IO is built around the ComputeModule5-CM5, from the Raspberry Pi family.

How big is the CM5IO PCB?

The CM5IO measures 160 × 90 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the CM5IO?

63 components, from 42 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 CM5IO design files?

From the mindhashnl/yggdrasil 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 CM5IO design in my own project?

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

Can I test firmware for the CM5IO 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.
