Button Pad 2x2 - Breakout PCB

This is a straightforward breakout board for button pads. Each LED and button is led out to the side connectors, which are soldered to the back of the PCB. To minimize pad deflection, it's advisable to trim the connector leads on the button side as short as possible. Now, it comes with footprints for diodes! You can use the very affordable 1N4148 through - hole diodes. These diodes can isolate the switches, making decoding a bit easier. Included documents are the schematic and Eagle Files.

Using this 2x2 Button Pad Breakout PCB is easy. First, check the side connectors where each LED and button is connected. Make sure to trim the connector leads on the button side as short as you can to keep the pad stable. When it comes to the diodes, just use the 1N4148 through - hole ones that fit into the provided footprints. They'll help isolate the switches and simplify the decoding process. As for maintenance, keep the PCB in a dry place to avoid damage. If you need the schematic or Eagle Files, they're available for reference.
