## Steps
In my experience it is easiest to solder the lowest components first, and the highest last, since you need to turn the PCB around with the components on the other side when soldering(and then you want the loose ones to rest directly at the desk). Thats why I suggest starting with the diodes, then the MCU, the switches, the RJ45 socket and lastly the encoder.

You need to be careful to solder the diodes the correct way. The line on the diode should always be closest to the square pad of the footprint, NOT the round one. The PCB supports SMD and throug hole diodes, and you can choose which side you want to mount them. I suggest mounting them on the top side, to keep height of board as low as possible.

If you use through hole diodes and have sockets for the MCU, keep the legs you cut off and use them for socketing the MCU.

These are lower profile, and easier to solder straight, but more expensive: https://www.aliexpress.com/item/1005006248653180.html (9P PH3.5 Female Header). Socketing is a long term choice: you can reuse mcu for another build, or more importantly replace it easily if it breaks.
[^2]: 5 mm wide and 2 mm high is fine. If you know you will only use the keyboard on a mat or with a case, you might not need this, otherwise you want them.
