- This video is sponsored by PCBWay. Only $5 for 10 PCBs and Only $4.98 for 3D Printing + Express 24 hour service on www.pcbway.com/ Hot-swappable mechanical keyboards allow users to change the mechanical switches. This way they can experiment with various options of clicky, tactile and linear mechanical switches with various tech specs and colors: red, blue, brown, green, silver, etc. Kailh offers hot-swap sockets for surface-mount technology (SMT) assembly. In this video we will explore the advantages and disadvantages, compare them to holtite sockets, explore a printed circuit board for mini mechanical keyboard designed with the free and open source CAD software KiCad. Furthermore I will demonstrate hand soldering of Kailh hot-swappable sockets on a prototype board with XIAO module and Raspberry Pi RP2040 microcontroller manufactured by PCBWay. The keyboards used in the video are powered by the open source firmware QMK and KMK.

This channel is severely underrated. Great explanations of what would otherwise be esoteric topics!
Thank you for the kind words! I am happy to hear the content on the channel is useful.
Awesome video, is it possible to get access to the PCB you designed ?
Yes, absolutely, it is all open source and the whole KiCad project is in GitHub: github.com/AnaviTechnology/anavi-arrows
However, due to lack of time I can't provide KiCad support if there are any questions. I plan to manufacture kits with assembled PCBs later this year.
Hello is not possible to use this with a Asus PCB red MX switch right? Because doesn't have the proper pads to he solder on with the kail hot swap?
The printed circuit board of the keyboard must be designed in a way to have pads for SMT assembly of the kailh hot-swap sockets. Otherwise these sockets support any MX compatible switches (aka as long they are MX they are supported).
is it possible to desolder dead hotswap sockets to change them? or will that run the pad?
Yes, it is possible to do it. It won't damage the pad if you are using properly the right tools like hot air station to remove the old hot-swappable socket.
@LeonAnavi would a desoldering gun with a iron work well enough?
@@stinky5628 a desoldering gun is more appropriate for through-hole components. These hot-swappable sockets are for SMT. A hot air station will be more suitable to carefully heat the two pads of the socket and remove it with tweezers.
@@LeonAnavi thanks for the info! I'll look into hot air stations:)
PCBway will include the hotswap sockets for you?
For this particular prototype I have soldered the hot-swappable sockets manual. However, they provide assembly services so you can take advantage.
@@LeonAnavi Awesome, I'll have to give them a try.
