RGB Touch Mini
RGB Touch is an ESP32-S3 based interactive LED display, featuring a 12x12 touch-based RGB LED matrix and a host of other features.
RGB Touch Mini is designed for makers looking to create interactive LED projects, from HID controllers and MIDI devices to mini games and wireless communication tools.
12x12 Touch-Based RGB LED Matrix
A grid of 144 individually addressable RGB LEDs paired with capacitive touch sensing (MPR121) lets you build interactive displays, games, controllers, and more. Single-finger swipe detection is supported.
ESP32-S3 Core Performance
Powered by the dual-core 32-bit ESP32-S3 processor running at 240MHz, along with 8MB QSPI Flash and 2MB QSPI PSRAM, RGB Touch Mini has plenty of power for your projects.
Audio and Motion
A built-in I2S audio amplifier (MAX98357A) drives an internal 8-ohm, 2W speaker for sound, music, and voice playback. A 3-axis IMU (LIS3DH) enables motion-based interactions and orientation detection.
Battery Support
RGB Touch Mini supports a 1S LiPo battery (up to 062540 in size -- 25mm wide, 40mm long and 6mm thick) for portable operation. Battery charging works even while the device is powered off, and battery voltage detection is built in.
An optional Large Battery Case (LBC) expansion attaches to the bottom of the standard case, allowing batteries up to 90 x 80 x 8mm in size. The LBC comes with 4x M2.5 x 10mm screws and a 1.25mm to 2.0mm converter cable to allow larger batteries with a 2.0mm pitch JST connector to plug into the 1.25mm PicoBlade connector on the RGB Touch Mini.
Hardware Protection and Buttons
ESD protection on USB and all physical buttons, 5V presence detection, and convenient hardware buttons (Power On/Off, IO0/Boot, Reset) for development and daily use.
Firmware
RGB Touch Mini ships with firmware that includes different play modes and a settings menu. The firmware source and additional projects (including multiplayer Tic Tac Toe and a WIP Battle Ship game) are available on GitHub. There is also an initial MicroPython library in the repository.
You can also flash firmware directly to your RGB Touch Mini via the web using the RGB Touch Mini Firmware page.
Is This Multi-Touch?
Though you can touch as many LEDs as you like, RGB Touch Mini is not a multi-touch device that can track multiple individual touches or detect multi-touch gestures. Using 2 fingers (or more) at once will generate typical ghost touches. RGB Touch Mini can detect single-finger swipes though.
