Capacitive Touch keypad for Capacitive module 16 keys

The 16-Key Capacitive Touch Keypad is a touch-sensitive keypad designed for capacitive touch sensing applications. It works by detecting changes in capacitance across its 16 electrode touch pads, enabling reliable touch input without mechanical switches.

The keypad is specifically designed for use with capacitive touch controller modules such as the TTP229 Touch Module, which communicates with microcontrollers using the I2C interface. The keypad can easily connect to Arduino, Raspberry Pi, STM32, ESP32, AVR, PIC, and other embedded systems through compatible touch controller modules.

Its compact and lightweight design makes it suitable for professional control systems, smart home interfaces, DIY electronics projects, and educational applications. Since there are no moving mechanical parts, the keypad offers improved durability, silent operation, and long operational life.

The touch pads are numbered from 1 to 16, and the labels can also be customized or marked using a felt pen for specific application requirements.
