Steps
Preparation
First, we have to do a test on the PCB to make sure the PCB is working properly. Install the OLED module in the 4-pin female header, like the image below.
Now, It’s ready to be connect to USB. Check if the OLED module and rotary encoder are working. For the keys, use a piece of wire or tweezers to verify it’s working properly.
Switches and Plates
Snap a switch into each corners first.
Carefully snap the switches to the sockets. Be careful so you don’t bend the contacts.
Then, add all the remaining switches. Double check the bottom and you should see all the contacts in the sockets.
Top case
First, remove the OLED module from PCB, if you follow the preparation steps. Insert the module into the slot on the top case like below.
Lay down the top case on flat face. Then
