Hello,
I made the leap after a fair amount of research and bought an ezbv4 last night. My initial application is static so I deferred buying a battery..unless I missed it I did not see a wired power adapter in the store. I have read some of the power tutorial.. I did get the power base also.

I am looking for a recommendation on finding a power supply.

I expect to eventually run 18 micro servos and possibly up to five brushed motors. Three of these are larger and draw 1.8a stalled.. I never expect to have all the servos running at once.. I plan to have the. Brushed motors running through escs so their power can be drawn from another source. If you follow.

I want to make sure I have something soon.. So to start I could use a dc wall wart say 12 volt 2amp with 2.1 mm barrel?

Can someone throw out some links to recommended sources? I am inclined to go to one of the mote prominent online robot shops. Does that make sense?

@Jeremie, I can't argue with anything you wrote. This is a great discussion about the different options and methods one can use to get around different issues that always come up with power distribution and load. Each build is different and people have different resources , needs and methods. If a person has the ability to buy a properly sized switching power supply at the start of a build and has the room to install and properly wire it, then good for them. No money, availability or space for a monster power plant? Then it's great that adding caps will prop up the EZB when needed. There's nothing wrong with using a sledgehammer to kill a mosquito if that blood sucking bug is as big as a cow or is really pissing you off. Kinda feels good when you kill one like that anyway.:)

@Jeremie

Thanks for the info! I purchased 2x 1.5F 5v supercap's which has internal balancing circuity. Put them in series to get 10v rating, I used them on my Inmoov with EZB controller 'INPUT' voltage side ( 7.4v ), works a treat and stops intermittent brownouts.

Also these supercap's wasn't expensive, at £4 ( $6 ) each.

Cheers,
Chris.

@jeremie, do these caps have to be placed on ADC7 or can it be on any of the ADC ports thanks.

Any port will do. 3.3V and GND is shared among all the ADC power pins.
