From the project
BelayBox reference hardware
This repository contains two reference board designs meant to get started with EVerest with a fully working hardware and software solution, entirely open source. They are meant to be developer friendly, not mass production friendly, keep that in mind when using this as a start to design a product. They are designed with KiCAD 6 (https://www.kicad.org/), make sure you use the latest version of KiCAD.

EverestCM4: common questions
What microcontroller does the EverestCM4 use?
The EverestCM4 is built around the ComputeModule4, from the Raspberry Pi family.
How big is the EverestCM4 PCB?
The EverestCM4 measures 112.7 × 67.8 mm, has 4 copper layers and is 1.64 mm thick.
How many components are on the EverestCM4?
207 components, from 74 distinct parts. The full bill of materials is listed on this page.
Where can I download the EverestCM4 design files?
From the PionixPublic/reference-hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the EverestCM4 design in my own project?
Yes, under the terms of its CERN-OHL-P-2.0 license, which PionixPublic chose for the repository.
Can I test firmware for the EverestCM4 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.
