So far, 3 of the keypads have a least 1 key that doesn't work. Also, the connector strip is very cheap. The copper trace pulled off when soldering. Keys lack tactical feel. Not recommended.

I've connected this to some small microcontrollers like ESP32 and RP2350 and it works. input is recorded and you can program the buttons to do various things... it looks nice and would work well in prototyping projects.

Tried them out with my own sketch and the official arduino keypad library both worked flawlessly not sure what to use them for yet but they feel quality and durable and work as expected great for any tinkerer

All 4 I received have at least 2 buttons that do not work. 4 doesn't work on any of them. Some you need to press very hard. Buy something else.
