README
README.mdFirst PCB – Eco-Car Onboarding PCB
A basic PCB designed in KiCad 10.0 as my onboarding project for UAlberta Eco-Car. The goal was to learn the complete PCB workflow (schematic capture, footprint selection, layout, design rules, and fabrication outputs) before contributing to the team's electrical systems.
Overview
Built without a specific purpose in mind, more of a general development board, with a USB-C connector, 4 push buttons, 10 configurable LEDs, connections for I2C, SPI, a mini OLED screen, and general purpose pins so external modules can communicate with the MCU (STM32F103C8Tx).

Questions
How big is the FirstProject PCB?
It measures 71.4 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FirstProject use?
70 parts, built around the AMS1117-3.3 and USBLC6-2P6. 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 FirstProject KiCad files?
From the srrizviii/firstPCB repository on GitHub, at the commit this page was made from: the board is firstProject.kicad_pcb and its schematic firstProject.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FirstProject design in my own project?
Its repository states no licence, so its author keeps all rights: ask srrizviii before reusing the design.
