The TTP223 Capacitive Touch Sensor Module is great for adding a capacitive touch key to your project instead of the old fashioned push buttons. This module features a low power consumption and a wide working voltage range.
An onboard LED will give a visual indication of when the sensor is triggered. When triggered, the module’s output 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.
Specifications:
- On-board TTP223 capacitive touch sensor IC
- Status indicator LED
