Description

Description:

  • The MPR121 capacitive keypad uses the MPR121 and 12 touch sensitive pads to give you a simple 'keypad' with an I2C output
  • The board also has four mounting holes allowing it to be used as an input system in place of traditional buttons
  • These keypads function by measuring the capacitance of twelve electrode points
  • When an object comes close to the electrode connector, the measured capacitance changes. This signals the MPR121 that something has touched a ‘button’
  • Size:approx.75*50*3mm

Package Includes:

  • 1x MPR121 Capacitive Touch Keypad Shield Module

Note:

  • This keypad outputs 3.3V logic. If you are using a board which only accepts 5V logic, you will run into a problem. You will want to use a logic level converter, or a board which accepts 3.3V logic
