Cheap, very flexible and very versatile matrix keypad. Used this to replace a broken Microwave input panel and even after months of intensive use it performs well. Has a clear feeling of when the "click" connects. Glue strip on the back is strong enough to fix, and hold it in place without any problem. No big con's I can think of. Other than ... Read more
An easy to setup 4x4 keypad. Easy to connect and start using - just use one of the libraries available and you are ready to go. You can use the characters as described or use your own - just print and glue above. Really easy to do so. Flexible. Cable is a bit short. Feels fragile. There are lots of examples available for arduino and pic. Fairly easy ... Read more
As described, very thin, a little flexible (you could stick it to a curved surface), clear keys with nice 'touch'.
As mentioned it can be used with the keypad library here http://playground.arduino.cc/Code/Keypad The header looks like it might come out if pulled hard, so be careful with it Works nicely with the keypad library and the following code:... Read more
The quality of the keypad is ammazing. It cames with a self adhesive transparent pelicule on the back of the keypad. When you lift it you can see the conection of the rows and coluns of the matrix. To use with Arduino, you can select the standart keypad library but you have to change the symbols of the buttons. Use the example of the arduino and change ... Read more
It's so thin that it is easy to glue it to something instead of having to drill a lot of holes. The buttons aren't super sensitive so you won't accidently press the wrong button. No proprietary connectors so hooking it up won't be the problem. Small enough to be used in various applications, buttons large enough even for fat fingers. "Buttons"... Read more

Small enough to be used in various applications, buttons large enough even for fat fingers. "Buttons" are easy to press, with discrete "click" feeling - no wondering "did I press this?" Material is quite strong, yet flexible. Does not come with holes or other dedicated means to fix this keypad in position (the glue on the ... Read more
You can use it to build your own projects, like a simple circuit with a PIC18, and it will work correctly. I´ve been using it for 3 months and it doesn´t seem to break in the future. Because its construction is in plastic, the first impression is that this article is a bit crappy, but nothing is further from reality.
Very strong To connect ... Read more
