This Matrix Keypad 3 X 4 has 12 buttons, arranged in a telephone-line 3x4 grid. The keys are connected into a matrix,hence only 7 microcontroller pins (3-columns and 4-rows) are required to scan the pad.
It's made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything. The keys are connected into a matrix, so you only need 7 microcontroller pins (3-columns and 4-rows) to scan through the pad.

The consignment was not dispatched as per committed date and had to pursue for dispatch information. The courier didn,t deliver us despit lying in Jaipur and we had to personally collect it from Courier Hub adding to inconvenience. The logistics need to be improved. Just a feedback.
Bought this from this website, stopped working within a month. Support made me wait for weeks, slow response.
At the end the Abhiram from the technical team tells me I should take it to some local electrical repair person who might be able to change the element.
Disgusting quality and service. I was told it does come under warranty but still no solution.
I've sent them photos, videos, nothing. Disgusting service.
