This keypad has 4 buttons, and since every key has its own wire line, no matrix code is required - just treat these like every day switches. The membrane is soft and has a removable paper backing to expose a strong adhesive so you can stick this on an enclosure.

This board has 18 total 'I/O' pins, 10 columns and 8 rows, which can be arranged as a matrix of buttons for a total of 80 switches. Or you can use any subset as individual GPIO input or outputs. The nicest part of the keypad driver is that it has a 10-element event FIFO queue. Since it's I2C (StemmaQT/Qwiic/EasyC compatible) it's very easy to use with any microcontroller or computer.
