Bret did you need to ground the EZ-B to battery - ? Or did it work fine without it ? Just curious because I may be using some high torque servos also. thanks J.W.

The battery powers both the board and the servos so they do share a common ground.

Hi Guys,

I just want to check something here as I'm used to using Lipo batteries with BEC's (battery eliminator circuits, or voltage regulators) and have never needed to power any servos separately but Wall-e will need separate power to his drive servos and a couple of others so could someone please check my pic below to see if it is correct, as I need to visualise(yes we spell it with a s not a z lol) stuff when it comes to electrics and electronics.

Thanks heaps

Rich

@RichiesRC you need to have both GND and +VCC attached to your 6V battery and only the signal attached to the board.

@bret.tallent so no ground from the separate 6volt supply to the board?

Like this then?

Thanks Rich

That is how mine is set up and it works great.

Yea rich that's the best route to go with , seperate power supplies , I recommend not using the AA battery holder , either use a 6v lead acid or just another battery of choice your using on the servos, dj said he managed to get a all day run time using ub645 6v 4.5ah battery that usually go in a omnibot

Thanks guys,

I will be using a 11.1volt 3500mAh lipo for the lot with a 8amp UBEC at 6volts for the servos. I can plug the lipo (will have a lipo alarm) straight into the EZ-B though, is that correct?

He will also have a small 6volt Nimh pack to drive his charge level panel that will be able to be solar charged when he opens his solar panels.

Wall-e will be having 17 or 18 servos plus a heap of peripherals this would mean that I will need two EZ-B boards from what I have read and been told.

I will try and get some progress photos done tomorrow.
