About the USB Daughterboard PCB

USB Daughterboard is an open source PCB design by Croktopus, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 28 × 25.5 mm, with 6 components from 5 distinct parts.

It belongs with the keyboards and dev boards & breakouts designs in this gallery.

From the project

If you just want to have a CBC1 PCB printed, you'll want to take the gerbers.zip file to your PCB fab of choice (I recommend JLCPCB for the price), as well as the gerbers.zip in the daughterboard directory.

I've also got all the KiCad files in here if you want to play around with making your own modifications.

Once you have your PCB (unless you got it assembled for you), you get to do all the super fun SMT soldering! This is easily the worst part of the process IMO, but you can get through it in a few hours. If you haven't done this before, look up some youtube tutorials before you decide…
