Adafruit 12-Key Capacitive Touch Sensor Breakout - MPR121
Adafruit Industries, LLC mail
The MPR121 has support for only I2C, which can be implemented with nearly any microcontroller. You can select one of 4 addresses for a total of 48 capacitive touch pads on one I2C 2-wire bus. Using this chip is a lot easier than doing the capacitive sensing with analog inputs. This sensor uses a 4-pin Sparkfun Qwiic-compatible connector called STEMMA QT, which allows the sensor to communicate over I2C without soldering.
