I recharged my NiMHs (five 1.2v enercell batteries, 2500maH each) and plugged them into the servo port on the board. Hexy woke up as usual, but this time there was a small column of smoke rising from the board, then nothing.
Now when I plug in the USB the green LED glows dimly then goes out. There is no red LED.
When I plug the batteries into the logic plug, no LED (green or red) and no response from Hexy at all.
But when I plug in the batteries to the servo port, the servos still seem to be getting power (they whiz and move).
My computer doesn’t recognize the board anymore either (Windows 7 64 bit).
I think I bricked it, but I’m not sure how I did it (1.2 volts times five is still under the servo port’s limit). The store’s closed so I can’t order a replacement; but I’m hesitant to use the Servotor board again if it’s going to burn out on me through regular use. But even so, is there another board I can use to tide me over until I can pick up another Servotor one?
EDIT: FIXED THE ISSUE
I isolated the issue by unplugging the PING sensor. For reasons I don’t fully understand yet I plugged it into the four-prong plug near the center of the board. After unplugging the sensor, Hexy came alive again
