Pins first, then flip the PCB to the other side and use long flat
nose pliers to band the two fixed legs of the USB socket a little
bit close then solder these two fixed legs.
Then solder the 1206 FUSE, usually in golden color with mark [ 4 ]
on it, easy to find.
After soldering these two components, you can plug the USB power
in and measure the fuse output pad to see if it has 5V output.
The next part of this step is soldering the main MCU chip, it
is a LQFP32 package MCU with [ 105K6T6 ](or 005K6T6) mark on it.
Please check the first legs position. For soldering the QFP stuff
like this, we recommend that you use a short Polyimide Tape to
glue the chip on the correct location of the PCB first, then solder
one corner, if all fine, solder the other side pins in the next,
