How do I read the keys with a microcontroller?
Each key connects one row line to one column line. Check the pin mapping on the keypad tail before wiring. Scan the lines in software, typically using internal pull-up resistors, and read which row and column are connected when a key is pressed.
Can I use it with 5V or 3.3V boards?
Keep the signal voltage within the rated maximum of 35 VDC and the current within 100 mA. For 3.3V microcontrollers, use the pins at their logic level and enable pull-ups as required by your code.
