This is only an interest check for single switch PCB’s. I am currently working with some other members to develop (read I can’t run KiCad) a single switch PCB for people who want a custom layout but:
- Don’t want to pay for a single PCB or 3 from OshPark
- Don’t want to or don’t have the ability to solder the rows and columns directly to the pins of the switches
- Want to have a more secure method for back lighting
-
Want to try something a little bit different
We currently have a design but I am also looking for someone to check over the files when the final touches are finished. Right now I think it is a couple silk screen details getting touched up.
As of right now the design will allow for MX with in switch or SMD diodes, LED’s, and Alps switches. There are also inter connect pads (SMD style) to connect both the switch and the LED’s to the next and previous switches in the row and/or column. These PCB’s also only measure .5 inch x .5 inch so only the inter connect pads need to be desoldered to pull the switch. No through hole desoldering needed unless LED’s are installed without modding the top half of the switch housing. This should work with MX switches however I have no idea what the dimensions are in the plate for Alps switches.
Images will be released upon finalization of last couple details. If you are interested in ordering a set as a guinea pig for these or be willing to look over the files (please have PCB design experience) please send me a PM. These will be released open source so if there is any interest for a GB on these it will probably only be one.

After I receive these I will build them up into a small matrix for testing and depending on what happens I will probably open up a group buy.
If we can hit 600 units the price drops from $5 per square inch to $1 per square inch. At the reduced price it would only cost $26 to do a full 104 key layout. Other goodies are possibly in the future as well.
Group buy is live.
