Hi so just bought an ez board, quick question, what kind of batteries and voltage can be connected to these and can you charge whilst connected to the board on a stable power supply sort of a home base with charging setup ? thinking of a wall e that can charge himself whilst i am away so i can leave him running 24/7
Thanks

1.5volt x 5 = 7.5 volt battery pack
so isnt 12 volt too much?
I think DJ would have chosen a cheap 6v supply if the amp range would have worked most are not high enough in amp's
I attempted to add a pic of the batteries I want to use. The add image asks for a URL. Do I have to post my pic on an online album somewhere to get an URL? Tried using my file name on my computer. Don"t work.
Thanks,
Lloyd
I can't remember what that plug is called. What i did is if you look at the top of the board between the jack and the voltage regulator you will see a tiny Gnd and below that a Vin + I just soldered some jumper wires there with the same style plug as all my battery's have.
If you change the battery pack plug to that barrel plug... you will most likely need to change the plug on whatever charger your using also.
You will need to upload the picture to a site then link it here.
Anyways If your RC car's battery plug is common a hobby store may have one for your ezb... If its really common i may have some here ill give you for free (i cut the plugs off of everything) all my battery's have whats called deans plugs.

Alternate Power Adapter $3.84
Bret I would think just one of the omnibot batterys would work just fine all by itself.
Next: On the SparkFun motor controller. I got the positive hookup ( I think) which is "VM".
This positive should come from a seperate battery( per one of DJ's posts.) That being true basic electronics says that to complete the circuit it must return to ground on that seperate batt.pack. Right??? so, should I connect the battery neg. to the last (or bottom) ground on the output side of the motor controller? Since I will be using a seperate batt.pack for the servos, can"t I use that same batt for "VM"?
Should I install a seperate bus terminal ( inside my bot) for the seperate batt. pack?
Hope I didn't make that confusing.
The alternate power for servos on v3. You can do it, it's just a bit tricker and there's a reason. The v2.1 had a jumper. We had to remove the jumper becuase it was robbing current. The jumper was a weak link in providing the full capability of the peripheral Voltage Regulator.
So you'll notice that the pins for the jumper are still there. It's located on the bottom right of the board. On the backside, you'll notice there is a trace pad. If you cut that trace pad, then you will seperate the entire right side +5 power plane from the rest of the EZ-B
Then, you can put a pin there, and provide power to it.
If your ez-b is for a specific application, i'd suggest this. If it isn't, then i'd suggest ordering a small breadboard from eBay and making a tiny adapter board.
its 7.2 volt if you use rechargeable or 9volt if you use akaline.

I just got my custom kit and I need some opinions on power sources that I picked out? I really dont know which is best to use with the EZ Controller. Can you guys help me choose? I figure, I should be looking for a wall adapter/chargere and a battery pack.....

Thanks for the help...I really value your opinions
do ebay.
did i see a 7.2 volt battery in your list that put out 7.2 volt at 22 amp?
the ez b only handles up to 5 amp i believe.
if you can wait, get it from ebay from china. if you cant, you will pay more from usa sellers, but alot cheaper than radio shack.
you can buy some 7.2 volt on ebay and cut the wires and put them in parallel for longer lasting mah and stay at 7.2 volt.
there are $10-$15 12 volt power supplies rated at 5amp, you need a 2.1mm plug ones, and find them on ebay, these are the wall adapters for testing at a desk.
one auction said 2.1 and 2.5 is close enough to be the same but i dont think so.
someone correct me if i'm wrong.
you can also use up to 14 volt, so a 12 volt battery will work, but ez-b will get hot.
i was looking at 12 volt steppers, down to 9 volt. they are cheap on ebay!
will these work? the ones i seen were good for 3 amp.

They also have a 12V 5AH battery for 12-15 bucks. And they are re-chargable.
