The controller board is an STM32-based board designed specifically for the LGDXRobot2. It supports a four-wheeled Mecanum chassis and can be adapted for other configurations.
The source code is available in the LGDXRobot2 MCU repository (GitLab | GitHub).
In addition, the controller board has an open-source PCB design, which is available in the LGDXRobot2 Design repository (GitLab | GitHub). The design files are located in the Board folder and require KiCad to be installed.
