Double-sided Sensor Module / Touch Switch Module - 4P/3P interface

Below you will find the specifications and connection information for the touch switch module:

Product information:

• PCB dimensions: 38.0mm x 24.0mm x 1.6mm
• Operating voltage: 3.3V or 5V DC
• Compatible interfaces:
  • 2.54mm 3-pin interface
  • 4-pin Grove interface (see pinout details)

Pinout details (for Grove interface):

• S: Digital output port
• N: Unused pin
• V: Power supply voltage (VDD)
• G: Ground (GND)

The digital output is VDD when the button is not pressed, and 0V when the button is pressed.

Electrical Characteristics:

• Supply voltage: 2V (min.) to 5.5V (max.) DC, typically 3V.
• Quiescent current (at VCC=5V): Typically 18 µA.
• Digital output voltage (at VCC=5V): 0V to 5V.

Connecting to Arduino:

Connect the 'S' pin of the module to a digital input pin on your Arduino. Connect the 'V' pin to the 5V or 3.3V pin of the Arduino, and the 'G' pin to the GND pin of the Arduino.
