GameBoy Keyboard

If you are up for some classic video games, GameBoy panel plus M5Core is the perfect combination. All you need to do is to upload an emulator onto the M5Stack and attach the GameBoy panel underneath. This is how it will be like:

The other panels are Calculator, Keyboard, Encoder, Joystick, Fingerprint, RFID and QWERTY Keyboard. You can apply them to those situations which are in need of inputting information and hard to control.

To reduce the difficulty of disassembly when removing the replacement panel, it is recommended to remove the M5Core and then disassemble the panel.
