Assembly of the Pi Wedge B+ should be mostly obvious and

straightforward. One thing to notice is that components are soldered to both

sides of the board. The headers that interface with the breadboard are on

the bottom of the board, soldered from the top. The other components go

on the top, and are soldered from the bottom.

Pin Alignment

To keep the breadboard pins properly spaced and aligned while you solder,

you can use your breadboard as an assembly jig. Simply insert the 17-pin

headers in the breadboard…

Pins in breadboard

Then place the PCB over them, and solder it in place. Notice that the PCB

is placed over the pins so that the signal labels are facing up.

Add the PCB

Be careful not to overheat and melt the breadboard while soldering the

pins. Zig-zagging between the rows will help distribute the heat. Also,

somewhat counter-intuitively, using a hotter setting on your soldering iron

will allow you to work more quickly, minimizing the risk of melting the

breadboard.

Shrouded Header

The shrouded header has a notch that keeps the ribbon cable properly

oriented. The notch should be lined up with the corresponding rectangle in

the PCB silkscreen.
