What is it?

This small PCB fits a single Cherry MX style mechanical keyboard switch and exposes all the connections for easy soldering.

It's designed for those of you interested in making hand-wired custom mechanical keyboards like the Dactyl Manuform

There are a bunch of of these around, but this one is different in that:

• It is designed to be used with Kailh hotswap sockets (for solderless removal of keyswitches)
• It has a slot for a SK6812 MINI-E downward-facing RGB surface mounted LED (you can get a bunch of them here
• Allows you to solder the entire key matrix before installing it inside the case. (no need to do this in place)

This design in particular has indentations in each corner so that melted plastic can be used to hold the PCB in place, without the need of glue or screws (though you could still use those if you wanted to)

I designed this when I was preparing to make my own Dactyl Manuform keyboard.

See.. it's layout and shape not flat and it's not possible to buy/make a single board with all the terminals for the key switches you need. This is when this small PCB comes in handy.

You could hand-wire all the key switches together but it would be messy and you would be hard pressed if you wanted to use Kailh hotswap sockets or any kind of RGB features.

Current version is v1.1

Sold in panels of 25 biscuits

Optional 3D Printed mount available

You can include in your order a 3D printed mount that comes in handy to hold in place a single biscuit in a position that is very convenient for soldering.

Just glue it or stick it to any flat surface and place the biscuit in the center. You can get a few to form a grid an speed up the process a little bit.

Alternatively, you can just print your own

Other things you will need to make use of these PCBs

You will need to solder a few things to these biscuits to make any use of them:

• 1 Kailh Hotswap socket for each biscuit/switch
• 1 Surface Mounted Diode for each biscuit/switch
• 1 SK6812 MINI-E RGB Led for each biscuit/switch (optional if don't want RGB stuff)
