BRAIN VOLTAGE TO POWER EXTERNAL DEVICE
As you can see in the photo, I have added a small board with several header pins on it ready to interface devices to the v2. at the moment I have wired the power from the head to it, (3.3 volt) perfect for the addition of headlights :)
The red and black cables labeled SVCC and GND are the two I tapped into so far.
Thanks to knitsu for his help in working out the best pins to try for a power interface, spot on !
