TTP223 Touch Key Module is based on a touch-sensing IC capacitive touch switch module. A capacitive touch sensor module based on the dedicated TTP223 touch sensor IC. The module provides a single integrated touch sensing area of 11 x 10.5mm with a sensor range of ~5mm. An on-board 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. Solder jumpers allow for reconfiguring its mode of operation to be either active low or toggle output. Technical Specifications: Operating Voltage: 2.0 V to 5.5 V Current Consumption: < 7 µA Start-up Calibration Delay: 0.5 Sec PCB Size: 15 x 11 mm Low power consumption. Power supply: 2 ~ 5.5V DC. Can replace the traditional touch of a button. Low Power Mode and Fast Mode Simple, easy to use, with Auto Calibration Output mode is set by Jumpers Package Includes: 1 Piece–TTP223 1-Channel Capacitive Touch Sensor
