QuoteGreat find on the 5-pin screw terminals! That Amazon bundle from Cermant is a steal at $0.45/piece. Definitely beats the Adafruit/Digi-Key price.

Thank you so much! I appreciate the compliments! I double-checked that Amazon Cermant link, and strangely enough, that product page seems to only sell 2-pin screw terminals now. Plus, as a fair warning to any interested buyers, a lot of the reviews for that product are quite negative.

These screw terminals may work well! From my experience, as I have used these terminals myself, the screws are quite small, and the screws are also flathead instead of Phillips. But these terminals do function well in terms of conducting current, even after soldering! These terminals work best under low mechanical strain (don't pull any attached wires very hard). Still, I suppose less mechanical strength is to be expected since the terminals are so small.

Has you considered using spring-loaded (push-in) terminal blocks instead of screw terminals? I've seen them used on other micro-boards; they seem like they might put less mechanical stress on the solder joints since you aren't torquing a screwdriver against them. Would those fit the standard 0.1" spacing?
