Description
The TTP223B Capacitive Touch Switch Module is a compact input device designed to replace traditional mechanical buttons with a touch-sensitive interface. It operates using capacitive sensing technology and provides a digital output based on user interaction. The module supports a wide input voltage range from 2.0V to 5.5V and features low power consumption with automatic low-power mode after inactivity. Built for stable and reliable operation, it can be mounted behind non-metallic surfaces such as plastic or glass for hidden touch applications. Ideal for embedded systems, control panels, and interactive electronics projects. Features • TTP223B capacitive touch sensing IC • Momentary touch output operation • Wide operating voltage range 2.0V–5.5V • Low power consumption in standby mode • Automatic low-power mode after 12 seconds inactivity • Digital output signal (HIGH/LOW) • High sensitivity touch detection • Supports hidden installation behind non-metallic surfaces • Compact PCB design 24 × 24 mm • Integrated mounting holes for secure installation • Fast response time in touch mode (60 ms) • Stable output with noise resistance • No mechanical wear compared to push buttons • Compatible with microcontrollers and Arduino systems • Supports both direct and surface touch activation Tutorials • Capacitive TTP223 Touc
