3x4 Matrix Keypad
73 units will be available shortly.
We include some header so you can plug this into a breadboard with ease, some light soldering is required to attach it. Or you can use plain wires if you like.
There's a great Matrix Keypad Arduino library that should work great with this item with minor adjustments. It's basically a sturdier version of our Membrane 3x4 Matrix Keypad. Note that the rows and columns are intermixed. The order from left to right is COL2, ROW1, COL1, ROW4, COL3, ROW2, ROW1
We also have a 4x4 version of this matrix keypad and a version that has phone-styling with letters printed over the numbers
