Compatibility of Non-arduino specific keypad (EOZ)

Projects General Guidance

Hello everyone!

I'm revisiting an old project using a keypad. In the past, I've simply used the arduino keypads such as these:

Arduino Keypad

I'd like to upgrade it to a sturdier type, but I am uncertain whether or not other keypads would be compatible. The one I have my eye on is this:

Datasheet for EOZ keypad

According to the datasheet it could be compatible. It's a matrix keypad for 5v.

But they are pricy, so I was hoping someone might be able to shed some light on this topic or even suggest sturdy keypads that definitely work with Arduino.

Thank you so much!

There is a version that has uses a matrix. And they're not for a specific voltage. The keys can handle a variety of voltages and for the LEDs (for the illuminated version) you have to use the correct current limiting resistors.

So you can use any type of these keyboards with your Arduino for the non-matrix versions you should use one with many I/O pins (p.e. Mega2560).

Any of the keypads linked will work with any Arduino.
