From the project

🍌🎹 Capacitive touch slider controller for rhythm games.

Capacitive touch slider controller for rhythm games.

Microcontroller board for use with LKP electrode boards. Supports up to 32 channel of self capacitance input. Includes a WS281x LED driver channel with protection resistor. Supports I2C or UART as communication methods.

For sample firmware for use with LKP-Core, see LKP-FW.

IMPORTANT: WS281x LED driver will not work on this variant. See errata. This variant is only included for documentation purposes and will no longer receive updates.
