I assume you are using the source files to make your own, keep in mind you'll need to solder all the MOSFETs and resistors on any boards you get from a PCB manufacturer, that said it not too hard.
I did make a run of these boards my self but as I mentioned, I have not posted the link for that run as it is off-site. I was considering selling a few here on the Trade Federation but I didn't think there was much interest. Perhaps I'll put a few up anyway, just in case.
Yes, thanks - I've already sourced the parts from Digi-Key. I've never soldered SMT devices before, but I should be able to figure it out.
I'm planning on using a modified version of JBKuma's aircraft plug design for the blade and hope to be able to swap between an RGB and a NeoPixel. That way I can make the NeoPixel later and just plug it it. One issue with making a standardized plug is that the power for the NeoPixel is different between this board and the DIYino Stardust 3, but I'm assuming that in the case of the latter it is so that the blade can be completely powered off in deep sleep mode. I'd like to use one plug design that I can use with either board and have interchangeable blades. I think I'll just connect the NeoPixel to ground instead of the mosfets for both boards, as I don't foresee needing deep sleep with the blade plugged in, unless there is some reason not to that I haven't thought of. That way, with a little modification to FX-SaberOS, I can run an RGB crystal off of the mosfets in conjuction with the RGB blade and have them still work with the NeoPixel blade installed.
As a side note, on NeoPixel blades Adafruit recommends using a capacitor across the power terminals to prevent spikes when powering on. I don't see this in the schematic. Is it necessary, or just a good idea?
