Description
This module uses the TTP223 capacitive touch detector to replicate a mechanical button without moving parts. It supports two modes: a momentary (no-lock) mode and a toggle (self-locking) mode. Supply the module with 2.5 V to 5.5 V, and connect its output to your controller or circuit. A single touch of the pad (or linked conductive surface) triggers the output; in toggle mode the next touch will toggle the output state. Low power consumption makes it suitable for battery-powered projects. On-board LED shows the touch state. Configurable output polarity (active-high or active-low) via solder pads or jumpers.
