Capacitive Touch Sensor Module for Arduino

Capacitive touch sensor module for Arduino and other microcontroller projects

One side has a 9mm x 9mm capacitive touch area, and a TTP223 touch sensor IC on the reverse.

An LED indicates when the switch is touched. It can be set to either a high or low output, and momentary or latching output by joining or not joining the A and B connections:

A open = High output when touched

A Closed = Low output when touched

B open = Momentary switch action

B Closed = Latching switch action

Voltage : 3 to 5VDC

PCB Size 14x10mm
