I bought a GoPiGo recently and was really disappointed when, having completed the build, the robot wouldn’t power up.
If the pi itself is plugged in to the micro-usb power supply, it boots up and I successfully connected to it as per the instructions.
When the battery pack is connected to the GoPiGo board and the power button is pressed, the LED on the red board does not light up at all. The lights on the pi itself flash as they do when the pi is booting up, but releasing the button stops the process.
I have tried this with brand new batteries as well as a set I confirmed were fully charged with my battery charger.
Following other forum posts, I also reinstalled the OS, with no change. Is there anything else I can try?
