What is VCS?
In modern vehicles almost 80% of the vehicle is controlled electronically. That's just VCS, a control system. Focused on electric vehicles but can be easily modified for other types. VCS consists of several units and modules, all connected by an area network bus, based on rs-485 and my own data protocol, allowing modularization. In this project you will find both the hardware and the software of each unit or module.

Questions
How big is the BaseModule PCB?
It measures 85 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BaseModule use?
67 parts, built around the STM32F103C8T6, MAX485ED, LM1117-3.3 and LM1117-5.0. 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 BaseModule KiCad files?
From the KarlVaello/VehicleControlSystem repository on GitHub, at the commit this page was made from: the board is modules/BaseModule/BaseModule.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BaseModule design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
