Its main chip is the ComputeModule4, from the Raspberry Pi family. Other key parts include the TPSM33625RDNR, 74HC595, SIP32431DR3, 74LVC1G07SE-7 and TCA9416DDFR. By type, the board carries 59 capacitors, 31 resistors, 20 connectors, 16 ICs, 4 diodes and 2 crystals.

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.

CM4IOv5: common questions

What microcontroller does the CM4IOv5 use?

The CM4IOv5 is built around the ComputeModule4, from the Raspberry Pi family.

How big is the CM4IOv5 PCB?

The CM4IOv5 measures 160 × 90 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the CM4IOv5?

137 components, from 72 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 CM4IOv5 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 CM4IOv5 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 CM4IOv5 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.
