Product description: MPR121 - Gator Breakout touch sensor - 12 channel - capacitive - STEMMA QT / Qwiic - Adafruit 4830
Gator Breakout sensorenablestouch detectionIt is equipped withMPR121chip. Made with capacitive technology, it provides the user with 12 channels that allow for12 independent measurements. To each channel individual touchpads andtouch panelscan be connected by means ofcrocodile cables. The module is compatible with popular Arduino microcontroller and derived boards, such as Metro board. It also works with Raspberry Pi. For communication it usesI2Cbus with address 0x5A.
Product is compatible with Arduino
