TTP224 - Touch 4Channel (Big)

The TTP224 4-Channel Capacitive Touch Sensor Module (Big) is a touch-based input board that replaces traditional mechanical push buttons with 4 capacitive touch pads. It uses the TTP224 IC, which detects the change in capacitance when a human finger touches or comes near the sensing area.

This module provides 4 independent touch outputs, making it ideal for creating modern, smooth, and maintenance-free control panels
