12-Key Capacitive Touch Sensor Breakout - MPR121
€6.00
Tax included
MPR121 capacitive touch sensor breakout module supporting 12 channels via I2C. Reliable touch detection for Arduino projects and user interfaces.
The MPR121 is a multi-touch capacitive touch sensor module that communicates over the I2C bus. It can detect up to 12 distinct electrodes or touch keys, making it suitable for creating simple user interfaces without mechanical buttons.
Typical Wiring
- Power: 3.3 V (3.3 V logic compatible)
- GND: common ground
- SCL: I2C clock line
- SDA: I2C data line
- IRQ: interrupt pin (optional, for touch change notifications)
An official Arduino library is available to simplify integration.
