## Description

The 8-channel TTP226 module adds capacitive touch controls to Arduino projects or other controllers, detects touch even through a shield panel, offers status LEDs for each channel, adjustable sensitivity in 64 steps, and a wide 2-5 V supply. It can work in parallel or serial mode via jumper, reducing connections to just 4 pins.
8-channel numeric keypad module (8ch), TTP226.
The module features an indicator LED for each channel, adjustable sensitivity in 64 steps, and an input voltage of 2 to 5.5V.
This module detects touch and is useful if you need to add a panel over the keys.
By adding a jumper on OP1, the module can be used in serial mode with the advantage of using only 4 pins on the Arduino development board.
