MPR121 3x4 Capacitive Touch Keypad Module Previous 
The TTP224 4-Channel Capacitive Touch Sensor Module is a 4 pad touch detector for electronic and control projects. It uses the TTP224 touch sensor chip and provides 4 touch keys for capacitive sensing. The module supports a 2.4 to 5.5V DC supply and is designed as a touch-based alternative to traditional push buttons. It includes 4 output pins, OUT1 to OUT4, and 4 board-level status indicators. Touch input can be applied through conductive materials and through thin non-conductive layers such as glass, plastic, fabric, or wood.
