All about the product
Adafruit company's 12-button capacitive touch module with MPR121 chip, operating in an electric capacitive (capacitive) manner. Uses I2C signal, making it suitable for Arduino or similar microcontrollers operating at 3-5V voltage. This module immediately filters the signal from external noise, so you won't have to do it yourself, and its sensitivity can also be adjusted. With one Arduino Rx/Tx connection, you can use up to 4 such modules, as they have four I2C addresses, allowing for up to 48 touch sensors.
Specifications:
•Operating voltage: 3-5VDC
•12 channels (can choose one of four I2C 7-bit size addresses)
•LED light indicates detected touch
•Dimensions: 33mm x 19mm x 2mm / 1.3" x .8" x .1"
•Weight: 2.2g
