How to Use

This module is simple to integrate into your electronics projects. Connect the TTP223 module to your circuit using the VCC, GND, and I/O pins. VCC should be connected to the power supply (2.0V-5.5V), GND to the ground, and the I/O pin should be connected to your microcontroller or logic device input. Once powered, place your finger near the designated touch area within the 5mm range to activate the sensor, effectively switching between setup modes like Direct or Toggle. Utilize the capacitive touch module to adjust sensitivity with additional external capacitors (0~50pF) or by replacing a resistor to finely tune the touch response.
