Description:

1.The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption; When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.

Control interface: a total of 3 pins (GND, VCC, SIG), GND is the ground, VCC is the power supply, and SIG is the digital signal output pin;

2.Power indicator: green LED, it lights up when it is right;

3.Touch area: The area inside the icon similar to a fingerprint, which can be triggered by a light touch of a finger

4.Positioning holes: 4 M2 screw positioning holes with a hole diameter of 2.2mm, which are easy to install and locate the modules, and realize the combination between the modules

Features:
Low power consumption
Power supply for 2 ~ 5.5V DC
Can replace the traditional touch of a button
