From the project

KiCad projects and PCB designs for UCDFS electronic circuits.

Welcome to the University College Dublin Formula Student (UCDFS) KiCad circuits repository! This is the central location for all our electronic circuit designs, schematics, and PCB layouts.

This repository contains KiCad project files for various electronic circuits used in our Formula Student vehicle and projects. All designs are created using KiCad, an open-source electronic design automation (EDA) suite.
