As a follow-up to this post, my first PCB has arrived from the printer! She's a beauty (to my eyes, at least)...and so tiny!
I used my multi-meter to ensure that all the connections go where they are supposed to go, and to confirm that the connections do not go where they are not supposed to go. It looks like it's time to solder in the components and give it a go!
(Note, this'll also be my first time soldering surface-mount components...I designed the board with one SMT cap on the front and one SMT cap on the, just to give me a reason to give SMT soldering a try. I'm hopeful!)
Follow-Up: I finally assembled the PCB. Check it out here!
