I connected this to an Arduino board, used a script and when a code was entered, ran a servo to unlock a door.

Product delivered as advertised. However, the seller did not ever respond to my request for "solutions" as stated in the product description.

This is one of the more professional looking keypads on Amazon with good graphic design of keys and a good tactile feedback. However its bigger than expected, which is partly my fault for not asking, but they really should include the dimensions in the product description. FYI, the keypad measures 2.7 in wide by 3 in tall and 32/1000 of an inch thick with adhesive backing. Will update my review when I have a chance to test it.

These are very nice keypads for my Arduino clone projects. The Arduino "keypad" library works perfectly with them. I prefer the F1 thru F4 keys on the right side as opposed to "A", "B", "C" and "D". It makes for a more professional look when setup next to a display and using those keys for menu choices.
