9. RGB LED: The LED has 4 leads and it is polarized. The standoff is used to hold the LED at the
proper height above the board. Only one hole on the standoff is used. See how the leads are
short-short-long-short? Place the open end of the standoff over the single short lead next to the long
lead (77). Direct the lead out through one of the holes in the standoff (78).

The open end of the standoff should be up against the bottom of the LED body (79). Place the
LED in its position on the board. The longest lead goes in the hole with the tiny white dot next to
it (80). As you hold the LED perpendicular to the board, making sure the standoff is flush with the
board’s surface, solder it in place and clip off the leads (81,82). Be sure to not over-apply solder
to these joints; they are so close together it’s easy to bridge them.
