The Embeddinator MPR121 Breakout V12 Capacitive Touch Module is a versatile and high-performance 12-channel capacitive touch sensing module, designed to add intuitive touch-based human–machine interfaces (HMI) to electronics, robotics, and IoT projects. Powered by the popular MPR121 capacitive touch controller, this module can detect touch on 12 individual electrodes with excellent sensitivity and noise immunity.

Communicating via the I2C interface, the MPR121 breakout allows seamless integration with platforms such as Arduino, Raspberry Pi, ESP8266/ESP32, AVR, ARM, and other microcontrollers. It supports auto-calibration and baseline tracking, ensuring stable performance even in changing environmental conditions. The module also features an IRQ (interrupt) output, enabling efficient, low-latency touch detection without constant polling.

Operating over a wide voltage range (3.3V to 5V), the module is ideal for both 3.3V and 5V logic systems. Users can connect conductive pads, wires, or custom electrodes to create buttons, sliders, or touch panels using everyday materials such as copper tape or PCB traces.

Common applications include touch-controlled robots, smart home panels, capacitive keyboards, interactive displays, wearables, and educational projects. Compact, reliable, and easy to use, the Embeddinator MPR121 Breakout V12 module is perfect for developers looking to build modern, touch-enabled electronics.
