Shoplink: Extension-PCB (PCB)
This is a small additional PCB with:
two MosFets to switch something (i.e. LEDs)
switch power up to max. 55A. (Data sheet)
(! Using a Traco/Recom on the Extention-PCB the power will be reduced to the max. power of the used Traco/Recom => Data sheet - Recom + Data sheet - Traco)
an opto-coupler to connect a camara-activator
a 9V-Voltage regulator (e.g. for a videotransmitter etc.)
(optional) a 12V Traco (if you need stabilized 12V supply)

Please always make sure that the components like LED or Opto-coupler have the right polarity! (See Pics)
INFO
Is a Lipo used up to 4S a bridge can be soldered instead of using a 12V Traco.
Is the input-voltage greater (15-36V) a 12V Traco can be soldered in to provide the 12V at the outputs.
The lighting can be soldered on directly to Schalt1/GND1 or Schalt2/GND2 .
Connection
The connectors Lipo+ and Lipo- can be directly soldered to the connection line of the Lipo or in the right polarity to the power distributor.
The soldered servo-cable should be hooked up to the connector for J6/+5V/J7 of the FlightCtrl .

Examples
The two switch-outputs can be used differently. The outputs S1 and S2 can be switched directly. If you want to use the opto-coupler the output S1 is not in use.
Connecting the cables please make sure you have the right polarity. "S1"("S2") is plus (+) and "-" is minus (-).
An exception is given for connector "C-". Using the solder-bridge on the backside +5V is provided here.
If, i.e., the lighting on the Kopter should be controlled variably it can be hooked up directly to the PCB:
Activating a camera etc.
If you want to use the lighting and an activator for a camera you can do it in that way:
Activating a Canon-Ixus with CHDK-Script
Who is using a Canon Camera with CHDK can activate the camera over an USB connector (if that is supported for your camera by CHDK).
For that reason the solder-bridge on the backside has to be closed. The USB-connector is hooked up in that way:
