TTP224 4-way Capacitive Touch Switch Module

This is a 4 switch digital touch sensor that uses capacitive sensing technology. The TTP224 IC provides capacitive touch inputs designed for touchpad control with a four finger sized touchpad. The module includes jumper settings to configure key press output modes such as timed or toggle, and active high or active low options. Additional jumpers allow selecting response time between 60 ms fast mode or 160 ms low power mode.

The output side has a 6 pin header, with 4 pins intended for connection to the digital I/O pins of microcontroller boards such as Arduino or ARM STM32. Four SMD status LEDs indicate the state of each touch key. The TTP224 4 channel touch sensor is compatible with all Arduino boards and is suitable for HMI applications and mechanical button replacements.

Note: HW-138 board version functions the same.
