Capacitive Touchpad (TTP223)

Detect touch instantly with this TTP223 capacitive touchpad module, a simple for mechanical buttons. The TTP223 senses a finger through the pad (even behind thin plastic or acrylic) and outputs a clean digital signal, making it perfect for touch buttons, control panels, and interactive projects. No complex calibration or signal processing required the onboard controller handles sensitivity and debounce automatically. With low power consumption and fast response, it’s ideal for battery-powered designs and always-on interfaces. Just connect power and a GPIO pin, mount it in your enclosure, and add a sleek, modern touch interface to your Arduino, MicroPython, or MicroBlocks project. Use it standalone with any microcontroller, or snap it into the Genesis Modular system from Axiometa for plug-and-play integration. Works with Arduino IDE, MicroPython, or MicroBlocks.
