First post. Been here for a bit, and have enjoyed plenty of reading. Retropie has been fun on the TV, not it's time for a handheld.
Planning to layout my board, mostly as a learning exercise for something moderately more complex than I have done before. After looking at the construction of various boards here on the forum, many of them solder the Pi directly to the main PCB for the GBZ. Some of them also grab other modules such as an audio amp and solder those as well. This really simplifies the internal connections.
What I have not seen, is soldering a teensy/promicro, directly. other than some complication with the USB connectors, this seems like a good way to avoid some wiring. Anyone have any negative experience with doing this? Otherwise I may give it a whirl and see what happens.
Thanks.

Re: pcb direct soldering
I had much the same idea as you. While looking on Thingiverse user "kapakahi" page I saw this
It appears to be a pro micro connected directly(soldered with 2.54mm headers?) to a PRS common ground board which looks clean and inexpensive. Is kapakahi a member here? I would love to see more detail on this build or one like it

Re: pcb direct soldering
That's a Teensy LC. If you try that with a pro micro, you're going to have a bad time.
I've done a board with a Teensy 3.2 directly soldered. With Teensy's, you can directly solder the USB lines as well because those are on the bottom of the board. It worked nicely and I plan on doing it again.

Re: pcb direct soldering
A bad time because of the USB connections? Or a bad time because the pcb in the photo is seems to be designed for the pinout on the teensy? Just trying to understand if you have found an inherent issue with the pro micro.
