Faces Kit

SKU:K005

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.

USB Driver

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 want to play some classic games with M5Core, using the GameBoy panel with M5Core will be the perfect solution. All you need to do is upload the game emulator program to M5Core and connect the GameBoy panel. The connection diagram is shown below:

The other two panels are the calculator keyboard and the full keyboard, which you can use in scenarios requiring information input or complex controls.
When removing and replacing panels, to reduce the difficulty of removal, it is recommended to first detach the M5Core, then disassemble the panel.
