The TTP223B module is a widely used capacitive touch sensor module designed for detecting touch input. It operates on the principle of capacitive touch sensing, which allows it to detect the human body's influence on an electric field, even without direct contact (just a near proximity). Here’s a breakdown of its key features: Capacitive Touch Input: Replace mechanical buttons with a digital touch sensor for responsive and silent operation. Smart Mode Switching: Supports toggle (latching) and momentary (non-latching) modes using onboard jumper/solder pad. Microcontroller Compatible: Works perfectly with Arduino, ESP8266, ESP32, Raspberry Pi, and other 3.3V/5V logic devices. Low Power & Fast Response: Digital output with quick touch detection and ultra-low standby current consumption. DIY & STEM Ready: Ideal for touch-based switches, interactive art, wearable tech, robotics, and IoT projects.
