This 4x4 keypad is designed transform the Fri3d Camp 2022 Badge in a configurable bluetooth keypad. They PCB design has some nifty features built-in. The left most corner contains a diode bending corner, making sure that your diodes have their leads bent in the right spot will help during assembly. The other useful feature if a built in lube station. The X cutout will snugly fit a stem whilst the rectangular hole will fit the body the switch you're cleaning.
Before doing anything else, make sure you have all parts:
Optionally, depending on what you want to do
Use the diode bender in the corner of the PCB to bend the leads of the diodes.
The resistors are only required when you're using rotary encoders.
Preheat your soldering iron to your desired temperature and start soldering the lowest parts first. In this case that will be the diodes and resistors.
The boards supports hot plug sockets for MX switches, if you have those on hand, now would be the time to solder them on the bottom side of the board. Otherwise you can just solder your switches on the PCB
