I bought a GoPiGo for my son for Christmas. We have never been able to get it to power up. Even when we just connect the battery and turn the switch on, we have never been able to get the LED to come on. As far as we have ever been able to tell, the unit has never worked.
We have noticed two things with it: the power cable looks like it is wired backwards (positive is where the negative should be). Also, when I check voltage across the LED, it shows 0V, indicating a possible short. Reversing the power wiring doesn’t make any difference.
