For some reason the resisters I ordered from CPC seem to be smaller than what I would class as "normal" size. This caused delays in bending the legs to the correct size.
After further research I bought resisters about 3.2mm in length rather than the normal 6mm in size. I still haven't worked out what the difference is between them.
I decided the first Weather Pi would be a low profile version, so used 90 degree Molex connectors.
The PCB includes 3 LED connection points, but decided just to solder the LED's straight to the PCB.
