With these PCBs you can build your dream keyboard, now with lights!
thanks to the tiny size, this feature is included in any exotic DIY keyboard models like manuform

This project provides to handwired keyboards a support to have underglow keycaps. PCBs was designed for keyboard with different form factors, for example: dactyl manuform. Its geometry makes makers hard to desing flexible PCBs, and them could be available only for some kind of dactyl manuform. These 15mmx15mm PCBs are near to size of a keyboard Switch, so there can be placed in any custom keyboard, if a switch fits, a PCB will do it so, this is suitable for customizable keyboards. Every PCB was designed with a LED neopixel, 100nF capacitor and a 1n4148 diode.

Its tinniest size makes possible wire any keyboardboard you like.

 are you dreaming with a macropad? done! you can build it! 

Form factor is not a problem!

Some Dactyl manuform has places where comercial PCBs doesen't fits correctly, this is not a problem now

    Do you know I have a twitter account?
    I'm trying to push this project up sharing a lot of content about it on twitter,  some time lapse videos, fotos and new PCB & 3D designs.

  • Arrived new PCB design

    HI all,
    today arrived the last design of the tiny PCB for handwired keyboards.

    As I anticipated days ago, new PCB bring us the possibility of solder the led in two ways, inverting the direction of the data pins. Now, wire the lED, will be easier (I hope) for all of you. 

    Once you solder the LED you have to mark the white square (to know whats the direction of this PCB)

    Hi all!

    I've looking around aliexpress and founded these switches:

    These switches have a more compact size, with shorter total travel, I've write the footprint for these switches:

    I'll upload the PCB version of my project for this footprint

  • Finished numpad keyboard

    Hi all, just finished wiring and programming of my numpad keyboard using the same PCB used at the dactyl manuform keyboard, hope you like it!

  • New PCB design!

    Pedro Barbero08/04/2021 at 09:24 0 comments

    Hi all,
    I've designed a new PCB to improve some features:
    1.- Added 2 gaps for mechanical support for some switches

    2.- Connector pads are now through hole, are smaller too, but is necessary to add the to gaps described before.

    3.- now you can mount the sk6812 4020 twisted 180º too, so it swap the direction pin:

    Now there isn't DIN or DOUT silkscreen to indicate the data direction, when you solder the led you set de direction pin too.

  • Added numpad to equipment

    I also build a numpad to show you how PCBs can fit in any form factor keyboard.

    These PCBs can be used to build macro-keyboards with under glow keys too!

    PCB desing, it fits into more difficult places inside the dactyl manuform
