Nice, easy to user keypad for arduino project. Is perfect for small project where you want to add a numeric keypad. I am looking at using one for a new intercom system I am building as a project.

Nice product, maybe little too big

Fast and good. Thanks

bien reçu, rapidement et conforme a la commande

Works very well good quality.

If you are unfamiliar with how these work, each row is connected to one pin, and each column is connected to another pin. That means for this 3x4 keypad, there are 7 pins. When you press a button it connects the row pin to the column pin. Pins 1 - 4 are the row pins. Pins 5 - 7 are the column pins. 1,5 - "1" 1,6 - "2" 1,7 - "3" 2,5 - "4" 2,6 - "5" 2,7 - "6" 3,5 - "7" 3,6 - "8" 3,7 - "9" 4,5 - "*" 4,6 - "0" 4,7 - "#"

Great deal indeed, looking to buy more, the only disappointment way the way it was packaged. As electronic components, I expected to be packed securely like other companies inside a cardboard box with protective materials.
