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.

Yeti Power Board: common questions
What microcontroller does the Yeti Power Board use?
The Yeti Power Board is built around the STM32G431RBT6, from the STM32 family.
How big is the Yeti Power Board?
The Yeti Power Board measures 163.5 × 123.5 mm, has 8 copper layers and is 1.599998 mm thick.
How many components are on the Yeti Power Board?
259 components, from 71 distinct parts. The full bill of materials is listed on this page.
Where can I download the Yeti Power Board 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 Yeti Power Board 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 Yeti Power Board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
