Solder the Screw Terminal Blocks (Optional)
If you’re going to use them, insert the screw terminal blocks on the board, making sure that the
open side is facing outwards (to the left), away from the WiFi module. The open side of the
blocks (where the wires go) should face the markings on the board. Turn the board over and
solder the pins to the pads.
Get out your lighted magnifier and carefully inspect all of the solder joints. Make sure that
there are no solder bridges, particularly on the WiFi module. If something doesn’t look 100%
right, resolder it, removing it first if you have to.
Congratulations, you’re done! Time to make sure it works now…
