Powering option for BBII

The VL+ pin on my BBII is not working, as in that pin can’t screw and hold the wire that has power coming from my 9V battery. Every time half way walking controlling with PS2 controller that wire will come off from the pin.

Is there any other way I can power my BBII without using VL+ pin ?

Cheers.

Will it be a problem if I connect my 9V battery to VS+ and VS-, then enable the jumper for VS = VL on BBII ?
So that the BBII will have a 9V supply from the battery as well.

Is this recommended or no ? I want to confirm before doing anything stupid that might blows up the board and ATOM Pro 28.

If you use the VS terminal block, it looks like it would work when the VS=VL jumper is used. The small green terminals are hard to get a good bite on stiff thick wires. If the clamping screw is not striped out, I would try to form the wire so that it relieves as much tension as possible by bending it in shape the best you can. I know exactly what you mean about the wires popping out during movement. Another thing you can try is using smaller wires. The bot board does not require a lot of current to operate, so using a 26 gauge wire would be fine. Are you using the 9v snap clip? Those wires are small enough and should work with no problems.

It is very easy to miss align the small wires, and get them under the screw terminal opening, instead of inside it. Especially if the terminal is not opened up fully. Take care to look into the end of the terminal while turning the screw CCW. When it opens up all the way, stop, You can damage it by continuing to turn the screw after it is opened up. Insert the wire but make sure only the wire goes into the housing, not the insulation. The key to securing a good connection is to tighten it down enough to compress the wires a bit, but don’t go overboard.

Yes my wire keeps popping out. However I am not using the thick stiff wire from the battery that powers the servos, to power the BBII board, I am using the battery(9V) that powers the SSC-32 as well. So the wire that is connected to the small green terminal is already a very thin copper wire.

When I first got the BBII board the VL+ pin is already not screwing tightly as it should be. I have done the other terminals correctly. I have placed the thin wire INSIDE the opening as well, but it just not gripping and hold the wire tight enough after doing all the turning. Basically what I think is the screw that is used to secure the wire is not working anymore.

So what I am suggesting is that is it possible that I connect the 9V battery power supply(which at the same time supply power to SSC-32) to the VS terminal block on BBII board, and enable VS=VL jumper instead of using the VL terminal anymore, will that work to supply power to the BBII board ? I can easily experiment with it but I am afraid it might damage the BBII board and Atom Pro 28.

You’ve quoted the very answer to your question. :unamused:

Ya I saw, just wanted to double confirm. Thanks :slight_smile:

Wait, I just saw from the BBII manual saying that VS can only accept Vdc from 4.8V to 7.2V.

Does it mean that my 9V battery is not usable ?

Yes it will work.

Yes it will work.

The 4.8 to 7.2vdc is referring to servo voltage. 9vdc will be just fine if you’re not using servos on the Bot Board II.
