Hi DJ,
Popped my new chip in today. Still nothing.
I went through the diagnostics video and i'm getting all the right readings.
Board upgraded firmware fine and connects fine.
I'm not reading 5V on any of the D0-D19 connections.
I figure i must have popped something else? Possibly a voltage regulator?
What other things can i check to figure this out?
Help please!
I'm looking up the voltage regulator pinouts.
Hopefully I can do a quick swapout.
I have (6) more EZ-B's enroute but would love to resurrect this one if I can.
I just tested them.
The regulator closest to the DC barrel jack is getting 4.98v one side and -0.66 on
the other side. Where the other side is looking like 5v/5v.
Looks like the one is pooched.
For the life of me I cannot find the EZ-B manual that has all the specs. It used
to be online?
Where is it hiding? ;-)
Do you know the make/model of the voltage regulators?
Crap.. I just placed a Sparkfun order. Story of my life!
I'll see if RobotShop has them. I need to get a bunch of battery packs on the go anyways.
Hopefully that'll fix her up.
Thanx for your help!

Something to do with DOT having their panties in a knot.
Thanks for the help!
