About the Mimir PCB

Mimir is an open source Raspberry Pi PCB design by mindhashnl, published on GitHub. It is a 4-layer board measuring 86.3 × 178.4 mm, with 44 components from 24 distinct parts.

Its main chip is the C6782225, from the Raspberry Pi family. Other key parts include the TPSM33625RDNR. By type, the board carries 19 capacitors, 12 resistors, 8 connectors, 2 ICs, 1 switch and 1 diode.

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.

Mimir: common questions

What microcontroller does the Mimir use?

The Mimir is built around the C6782225, from the Raspberry Pi family.

How big is the Mimir PCB?

The Mimir measures 86.3 × 178.4 mm, has 4 copper layers and is 1.5842 mm thick.

How many components are on the Mimir?

44 components, from 24 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 Mimir 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 Mimir 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 Mimir 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.
