Faces Gamepad is a gamepad panel compatible with FACE_BOTTOM. It includes commonly used up/down/left/right, A/B buttons, and start/pause buttons, totaling 8 buttons. It is designed to match the layout of classic gaming consoles like FC and GAMEBOY. You can freely load games by flashing game emulator firmware or write your own games. The panel integrates an MEGA328 processor and operates in slave mode via the I2C communication protocol (0x08).
