Product Description of TTP223B Capacitive Touch Switch Module 

This touch sensing module is IC TTP223B. It has a capacitive touch switch module. When this sensor is in a normal state, the module output is low and it has low power consumption. The module output high when the finger touch sensor is the corresponding position. And the switch is low power mode. Its initial state is low and it has a high touch. Please don’t touch it is low. This module can be installed in such as surface plastic. It can be installed on the glass or non-metallic materials. It should be placed as the correct location of the touch.

Touch Sensor Interface:

This sensor has three pins (GND, VCC, SIG).

GND pin is for ground.

VCC is for power supply.

It also has a SIG pin which is a digital signal output pin.

It has an LED indicator. It has a Green LED as a power LED indicator.

It has a touch area similar to the fingerprint icon inside the area. We can touch the trigger finger.

It has 2 M2 screws positioning hole diameter is 2.2mm.

The positioning of the screws module is easy to install. It can be used to achieve an inter-module combination.
