a) No antenna, pads for additional RGB LEDs
b) more pads for RGB LEDs (in total there are 3 RGB LED areas, on the part that looks like an antenna, and in the lower left and right area of the board)
c) On/Off-Switch
d) Micro-USB for connecting to laptop
e) Micro-USB for additional energy
f) clock out, an SMA connector (X201) could be soldered here
g) clock generator
h) on-board PCB antenna
i) pads for SMA connector (X301) or external antenna
j) radio frequency part, for sophisticated applications you may want to cover this with a metallic shield to prevent irradiations


= Antennas

The board has a PCB antenna for the 2.5 GHz ISM Band, for stand alone operation on the Camp Area. For other frequencies an external antenna may be needed.

== How to attach an external antenna
To improve radio reception a little bit you can just press a thumb against the upper right corner and be a human antenna. 
The most simple real external antenna is a single-wire copper cable (others may also work). This can be pressed against an edge of the little black resistor on the top right corner.
{{:rad1o_7.png?100|}}

<note important>**When soldering an antenna or SMA connector, this resistor (R315, 0 Ohm) must be turned 90 degrees or replaced with a bridge, connecting the RF line on the left to the SMA connector pads on the right**</note> (then the 0 Ohm resistor will be sitting on the R314 pads; R314 and R315 share the upper left pad).

Resistor turned 90 degrees

Alternative: Add bridge, remove resistor
{{:rad1o_11.jpg?100|}}

You can also solder a copper cable permanently to the board:
{{:rad1o_9.jpg?100|}}

You can add an SMA connector so that you can connect an external antenna for your specific needs.

=== Micro SD slot

Optional, not fitted in camp version

Modell: 3M 2908-05WB-MG

=== RGB LEDs
Optional, not fitted in camp version

^ LED         ^ Port  ^ Location                                         ^ Color / Type   ^
| RGB801-808  | P8_0  | 6 on Antenna and 2 in the lower area of the PCB  | RGB / WS2812B  |

[[http://www.adafruit.com/datasheets/WS2812B.pdf|Datasheet]] 

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
