Hi,

I want to connect the 12 button numeric keypad to my own breadboard, and am having some trouble finding documentation on the keypad’s protocol. Before I start reverse engineering the arduino library, is there any?

Check the ‘Documents’ tab on the product page, that should have what you’re looking for.
