Well, tonight I sent of my orders to Digikey and pcbway.com. I really hope that I can:

a) assemble this board without stuffing anything up, and
b) that I haven’t screwed up the layout and the board works!

I guess only time will tell now. Oh well, if nothing else it’s already been a massive learning exercise which has been great.

Here’s the 3D render of the finished board design from Kicad:

Looking forward to getting those boards back now. I’ll post some photos once they arrive.
