The TP226 TTP226 Capacitive Touch Sensor Module is an 8-key touch detection board designed to replace traditional mechanical buttons with touch-sensitive pads. Using capacitive sensing technology, it detects a finger’s proximity within millimeters to simulate a button press. The module supports configurable output modes, response times, and power modes, providing flexibility for different applications. With onboard level indicators for each key, it ensures easy monitoring and integration. Operating on 2.4–5.5V, this module is ideal for interactive electronics, DIY projects, and touch-based control systems where low-force and durable input solutions are required.
