Product Description

This capacitive touch switch module is based on the touch-sensing TTP223B chip with a touch pad sensor contained within the PCB design.

The module features a 3-pin right-angled PCB header for power (VCC & GND) and button state, which can be connected directly to a micro-controller’s input pin. It supports both 3V3 or 5V operating voltages and has an on-board power LED indicator.

The board is approximately 24mm² and has four M2 mounting holes.
