*GitHub : https://github.com/rdiot/rdiot-s243.git

* Specs

Features:
Low power consumption
Power supply for 2.5-5.5V DC
The module is based on a touch-sensing 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.

Specifications:
Color: Blue
Module size:1.4*1.4cm
Modes: jog, self-locking

Package includes:
1 x Digital Touch Sensor Module
