The LEDs
There are two LEDs on the PCB: the power indicator and the RGB LED controlled by the processor.
The same technique as with all other components is followed: tin one pad and stick the component
down, then apply the soldering iron and a small amount of solder to each of the remaining pins one
at a time.
The power LED PCB footprint has an arrow showing the proper orientation of the component. The
LED has an arrow on the under side of the component which should be aligned with the arrow
printed on the PCB.
The RGB LED has the common anode marked with a green spot. This must be aligned with the white
spot on the PCB, in the bottom right corner of the package.
