Details
Touch Sensor Keyboard, 4×3 Matrix Touch Keypad with 12 buttons, MPR121, 3.3V, Capacitive, compatible with e.g. Arduino and Raspberry Pi: ✅ 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.
Key features
- ✅ 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
