Diddyborg and batborg
Forums:
Hi
I have finally assembled my diddy borg and he works fine. However, I am a little confused as to how the bat borg and piborgrev work together and how power is being supplied to the pi. is there a wiring diagram somewhere that explains how the set up works. The reason I ask, is i want to add extra sensors (ultrasonic and IR ) to the bot but don't seem to have access to the 5v pin. Any help would be appreciated.
cheers

Power from BattBorg to DiddyBorg
It should be fairly easy to get at the 5V from the cabling between the PicoBorg Reverse and the Raspberry Pi.
Image #1 below shows the two pins on BattBorg which supply the 5V rail, and the single pin which supplies the GND rail.
This is connected the other way up onto the PicoBorg Reverse, it is easiest to remember as the 5V pins are closest to the edge of the board.
Image #2 below shows what signals are on the 3-pin cables between the PicoBorg Reverse and the Raspberry Pi.
Both 5V and the GND are on the same cable, the one closest to the edge of both boards.
You should be able to get at the 5V from one of the two cables fairly easily.
It may be worth making a Y cable to keep things neat and tidy.

Thanks for the answer but i
Thanks for the answer but i would still like to know how the units work together and how the batborg powers the pi. Is there a wiring diagram anywhere. i have searched the site but can't find one.

Powering other devices at the same time
Hi, we don't have schematics of the BattBorg if that's what you are after. The only wiring diagrams we have are in the above picture.
Hopefully this helps:
Power comes in to the black connector on the BattBorg. The BattBorg then powers the PicoBorg Reverse (using the 5V and GND lines), and the comms cables which go to the Raspberry Pi carry the 5V and GND as well back to power the Pi. (The Pi just needs 5V & GND to power itself)
If you have more devices, such as another PicoBorg Reverse, or say an UltraBorg, when you daisy chain them, they split the 5V and GND out to their circuitry.
If you wanted to take off 5V for your IR sensors etc., you could either split the 5V and GND out to those devices, or you could use a second BattBorg. Using a second BattBorg is preferred especially if you are powering devices which require significant current.
