Feature:
4*4 Matrix Keypad Keyboard Module MCU for Arduino Atmel Stmap S1/2
External keyboard microcontroller expansion
The Keypad library allows you to read a matrix type keypad for Arduino.
4×4 numeric keypads are most widely used in numerous mini project which requires the user or the operator to give command to the system or to feed in some data
If you solder on a header, we highly recommend laying down some flux on the pads first, inserting the header pins, then soldering
