From the project

temp VMS VCU repo

A custom STM32C092RCT6 development and vehicle-control PCB designed specifically for the Viking Motorsports Formula SAE Electric vehicle control system.

The board is designed to fit inside a Cinch enclosure and provide a flexible interface between the STM32 microcontroller and the vehicle's external wiring harness. Rather than creating a dedicated PCB for every vehicle-control function, this board provides a common hardware platform that can be configured for different VCU applications.
