README
README.mdUCDFS Circuits Repository
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.
About
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.
Getting Started
-
Clone this repository:
bash git clone https://github.com/UCDFS/Circuits.git cd Circuits -
Open a project in KiCad:
- Launch KiCad
- Open the
.kicad_profile for the project you want to work on - The schematic (
.kicad_sch) and PCB layout (.kicad_pcb) will be accessible from the project manager
-
View/Edit Schematics:
- Click "Schematic Editor" in KiCad's main window
- Or directly open the
.kicad_schfile
-
View/Edit PCB Layout:
- Click "PCB Editor" in KiCad's main window
- Or directly open the
.kicad_pcbfile

When contributing new circuits or modifications:
- Create a new branch for your work
- Organize projects in clearly named directories
- Follow naming conventions: Use descriptive names for projects and files
- Include all necessary files: Ensure
.kicad_pro,.kicad_sch, and.kicad_pcbfiles are included - Document your work: Add project details to a README in each circuit subfolder

Questions
How big is the LTC6812-15W PCB?
It measures 73.4 × 117.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LTC6812-15W use?
252 parts, built around the PDZ7.5B, 1N4148W-7-F-CN, HM2102NL and VLMTG1400-GS08. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LTC6812-15W KiCad files?
From the UCDFS/Circuits repository on GitHub, at the commit this page was made from: the board is Kieran Care package/ENNOID_BMS - Slave/LTC6812-15W.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LTC6812-15W design in my own project?
Its repository states no licence, so its author keeps all rights: ask UCDFS before reusing the design.
