The TTP223 Touch Key Module is based on a touch-sensing IC (TTP223) capacitive touch switch module.

An onboard LED will give a visual indication of when the sensor is triggered. When triggered the output of the module will switch from its idle low state to high (default operation). Solder jumpers allow for reconfiguring its mode of operation to be either active low or toggle output.
