  • 1.the onboard TTP223 capacitive touch touch sensing IC
    2, board level status indicator
    3, working voltage: 2.0V-5.5V
    4, PCB board size: 29 (mm) x16 (mm)
    Capacitive digital touch sensor switch hand touch detection module
    Touch keys to detect IC, providing 1 touch keys. Touch detection IC is used to replace the traditional
    Design of a button. Low power consumption and wide operating voltage are the DC and AC features of the touch keys.
    Working voltage 2.0V~5.5V
    After power up to about 0.5sec of the stability of the time, this period of time not to touch the keys,
    All functions are prohibited at this time
    Self calibration is always performed
    When the key is not touched, the calibration cycle is about 4.0sec
    application
    Wide range of consumer products
    Waterproof electrical equipment
    Button key
    On board with blue LED indicator light
    Board size: 15.5 X 23.5 mm
    1 pin for power + VCC
    2 pin for the output OUT
    3 pin for power - GND
    Output OUT can directly control the relay module of our shop, you can directly enter the microcontroller IO or ARDUINO development board IO
    Module output mode can be selected. (with tin short circuit board of the A or B pads, you can change the output mode, short circuit to 1, off 0)
