Description

FACES Kit is a series of functional panels integration containing three most commonly used panels integration containing three most commonly used panels 'GameBoy','Calculator' and 'QWERTY'. With MEGA328 processor built inside, it works under slave mode through I2C communication protocol. With these 3 different panels, it will be very easy to support keyboard interaction with your M5Core.

Power on/off:
Power on: click the red power button on the left
Power off: Quickly double-click the red power button on the left
Note: By default, when USB is powered, it cannot be shut down**

Driver Installation

Click the link below to download the driver that matches the operating system. There are currently two driver chip versions (CP210X/CH9102). Please download the corresponding driver compressed package according to the version you are using. After decompressing the compressed package, select the installation package corresponding to the number of operating systems to install. (If you are not sure of the USB chip used by your device, you can install both drivers at the same time. During the installation process of CH9102_VCP_SER_MacOS v1.7, an error may occur, but the installation is actually completed, just ignore it.)

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.
