****# Faces Kit

SKU:K005

Description

Faces Kit is a collection of functional panels. The kit includes three commonly used functional panels: "GameBoy (gaming keyboard)", "Calculator (calculator keyboard)", and "QWERTY (full input keyboard)". It integrates a MEGA328 processor, working in slave mode through the I2C communication protocol (0x08). Use these 3 different functional panels as needed to achieve human-computer interaction between the user and M5Core.

USB Driver

Click the link below to download the driver program that matches your operating system. There are currently two driver chip versions, CP210X (for CP2104 version) / CP34X (for CH9102 version) driver package. After decompressing the package, select the installation package corresponding to your operating system's bit version for installation. (If you are unsure which USB chip your device uses, you can install both drivers. CH9102_VCP_SER_MacOS v1.7 may report an error during installation, but it has actually completed the installation, just ignore it.)

GameBoy Keyboard

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

The other two panels are a calculator keyboard and a full input keyboard, which you can use in applications that require information input and complex control. When disassembling and replacing panels, it is recommended to disassemble M5Core first to reduce the difficulty of disassembly.
