I want to solder a mini-USB breakout board to an A-Star 32U4 Micro.
Can I have some pointers where the wires should be soldered to?
Here is an example of connecting a similar USB breakout board to an Arduino pro micro:
"...4 cables were directly soldered to the pro micro: The UVCC at the polyfuse input, the D+ and D- at the output of their respective 22ohm resistors..."
Spoiler:
