From the project

This monorepo centralizes Olin Electric Motorsports’ KiCad designs and STM32 firmware into a single place. It helps with immediate contribution through standardized environments and automated CAN signal tracking. This unified structure makes sure that there is architectural consistency across all vehicle electrical systems.

Welcome to the Olin Electric Motorsports monorepo. This is the home for all of our electrical, firmware, and software work.

This document will help you get started contributing and walk you through important steps for working on the team.
