The mLink 4x4 matrix keypad is a panel mountable serial (I2C/IIC) 16 key tactile keypad. On the rear of the keypad is mounted a mLink module which continuously scans the keypad (with automatic debouncing) for any key presses. If a key is pressed the module stores the key as an 8 bit ASCII value which can then be read out of its serial interface. It is compatible with other mLink or standard I2C modules allowing you to daisy-chain several different types of modules together using only the two I2C pins of your microcontroller.
