The touch sensor module (touch button) can be used as a replacement for traditional mechanical buttons. It operates based on the TTP223-B system, which measures the capacity of the metal field on the module. The module has a connector in accordance with the Grove standard. Seeed studio 101020037

A module for building a mechanical keyboard with 16 buttons and backlight. Based on the RP2040 chip, it has sockets compatible with Cherry-MX switches. Pimoroni PIM567

The modTTP223 module is a capacitive touch sensor that detects touch on the sensor surface and generates a digital output signal. With its compact size (14 x 11 mm) and operating voltage range of 2 V to 5.5 V, it is ideal for integration with microcontrollers such as Arduino or Raspberry Pi in projects requiring a touch interface.
