I believe it is 5V ~ 17V or so....

Thanks, any way to verify that? I don't want to see the magic smoke.

@Richard R is correct.

Richard R is right. Here is EZ Robot tutorial in which D.J. says up to 18 volts. Mine had better performance at 7.2 volts.

7.2v is recommended voltage 17v is maximum however may cause the regulators to get hot (spec sheet says 17v but DJ has said 18v personally I'd go with the lowest of the two to be safe) 5v is absolute minimum however may cause the EZ-B to become unstable

@Steve3623, those numbers are correct... you won't blow your board....

Thanks everyone I appreciate the help.

Close the thread with whoever helped you the most.(not to pester)
