Romeo power problem
Thad 2011-04-14 08:34:58 7122 Views0 Replies I'm just getting started with the Romeo board and I found that the board will power on with the USB cable, but not with the 5 AA battery pack, i.e., it doesn't seem to be getting any power from the battery pack.
I checked the battery pack with a voltmeter and it is putting out 7.95 Volts, so I would think there is enough power there to activate the board. Does this mean the board is bad, i.e., if the board were fried would I be getting any power at all, even from the USB cable?
I connected the ground (black wire) from the battery pack to the GND termimal on the board and the red wire from the battery pack to the M_VIN terminal on the board.
I can still program the board and control the LEDs via the Arduino software (when the USB is attached).
My main question is, how do I know if the board is bad and I need a new one, or is it just a faulty connection? I have the VIN=MVIN jumper on the board.
