That’s what I call a good start to the weekend 🙂🙂🙂
The only soldering error was a short between power and ground on the USB power connector.
Design wise the backplane has a couple of footprint issues, and my attempt to keep the board smaller by placing components under and between the cards is proving less than ideal in practice. The taller components are actually fitting between the cards but it looks messy and there’s potential for damage from soldered pins.
