- Add platformio.ini for ESP32 DevKit (Arduino framework, espressif32 6.10.0) - Vendor ArduinoJson, MPU6050_tockn, SCServo, Simple_FOC, and WebSockets so a fresh clone builds without downloading dependencies - Add .gitignore rules for PlatformIO/IDE build artifacts - Add controller PCB Gerber and drill files
