AJMRTC MPR121 capacitive touch sensor breakout module is a 12-channel touch detection board with I2C interface. It uses the MPR121 dedicated capacitive touch chip to detect touch or proximity events without mechanical buttons. Users can adjust touch sensitivity to adapt different electrode materials and application environments. It communicates via I2C bus, consuming few controller IO ports. It can replace traditional mechanical keys to realize touch keyboard, touch button and interactive control functions. This touch module is widely used for DIY touch panels, human-machine interaction devices, smart control switches and Arduino & ESP32 embedded prototype development.
