Simple little beautiful piece. Any recommendation for start with pcb design? I have soldering and programming skills but never felt comfortable in pcb design or anything electrical related :/

I used KiCad for designing the PCB.

To start, you should learn the basic first. Youtube have a lot of that kind of video:

  • Schematic: Add Symbols, Labels, Wiring, Named Symbol reference, Assign Footprint (Remember to select the right footprint)
  • Board: Layers, Fill zone, Wiring.

Then you should learn how a keyboard works:

  • Learn how Microcontroller sends a key to computer
  • Keyboard matrix, how Microcontroller knows which key is pressed.
  • Make sure that your Microcontroller has enough pins for the matrix.
  • Learn how to use Diode

After that you can get back to KiCad and make a keyboard PCB. At this time, the hardest part is wiring, you will learn when you do it.

This is so cool, thanks for sharing! Once designed, how did you get your pcb made? Does KiCad offer a manufacturing service?

Jlcpcb is good. but I use a local manufacturing service.

Are you living in VN or abroad? If you happen to live in VN can you share the name of the service you used?

ai03 has a great set of articles explaining the 101 of making a keyboard pcb amn using KiCad. I started designing my own PCB a couple weeks ago and it was very helpful.

Understanding or knowning what components to use and why they have the value they have is the challenging part for me. Sometimes it's detailed in the documentation of the integrated circuit, but sometimes you just have to look for what others on internet did.

Good resources! Thanks for sharing. I'm also making my first macropad, but already ordered the PCBs.. anyways the tips from those articles will be useful for the next one.

I'd suggest KiCad, which is what OP used as well. It's free, and not really difficult and has a large community.

For what it's worth, once you have the circuit designed the circuit layout software can often route all of the tracks for you within parameters that you define (eg. Key placement, track and pad dimensions, minimising wire bonds to bridge over tracks etc...)

Digi-Key’s Youtube channel has a great tutorial series going through the whole process of PCB design with KiCAD. Highly recommend for someone just starting out.
