Descripción
- ✅ 12 CAPACITIVE TOUCH FIELDS - Arranged in a 3x4 matrix, there are a total of 12 touch sensor fields on the board for free programming. ✅ EASY CONTROL - The MPR121 chipset enables simple control via I2C bus, so that it can be easily queried using Arduino or Raspberry Pi, for example. ✅ ONLY 2 PINS REQUIRED - The control via I2C only requires two pins to query all 12 buttons. That means the remaining GPIOs of your microcontroller remain free. ✅ INCLUDING IRQ - The interrupt output (IRQ) is triggered when the button is pressed. The I2C bus therefore does not have to be queried permanently. ✅ PROVEN QUALITY - If, despite our quality controls, you have reason to complain, we at Paradisetronic will help you quickly and easily.
