-These are RGB LEDs with their own microcontroller, so all LEDs can be programmed individually. They are daisy chained, first the two in the lower area of the PCB and then six on the antenna on the top. So if you don't want to add all LEDs, or want to start with only one first, you have to follow the order "//middle left, middle right, antenna from right to left//" or bridge the data pins of the unused LED pads.
-:!: **Important note** :!: Due to a fn0rd in the layout the transistors intended to control power of the LEDs can't be used as intended. The transistor pads have not been populated. You either have to
-  - build some complex SMD sculpture using wires or
-  - simply bridge 2 of these pads (FIXME pic will follow). But then your badge will always be powered, even if turned off, so either:
-    - try to use a jumper or
-    - try to use a switch to bridge the transistor pads (with some wires one switch can be used for all three) or
-    - always disconnect the battery to turn the badge off.
-Sorry for that, but wouldn't it be boring otherwise? :-P
