M5 Faces Pocket Computer Kit
Best modular toolkit for hobbyists building custom handheld electronics.
The M5STACK Faces Kit is an End-of-Life (EOL) collection of functional panels designed to enhance human-machine interaction with the M5Core. This kit features three interchangeable panels: a gaming keyboard, a numeric keypad (Calculator), and a full QWERTY keyboard. The included panels utilize a MEGA328 processor operating in slave mode via I2C communication. It is an excellent toolkit for creating handheld game consoles, calculators, or data-entry peripherals, supporting development on platforms like UiFlow and Arduino IDE.
