I recently purchased an AstroPi board and several other components (from various resellers) and all of the components work as expected - except the LEDs on the AstroPi. I can control the PiGlow just fine, on the same board with the same instance of Raspbian. I can even access the sensors on the AstroPi, but the LEDs will not light up at all.
I am using a 2A USB power supply and all components are recently updated to the latest versions. I am using a class 10 16GB sd card from Kingston (though I have tried several different ones from several manufacturers, as per suggestions on a few other forums).
I have installed the UnicornHat lib and saw no errors during install. I tried running the example scripts (from the UnicornHat library) with both python2 and python3.
The kicker is that when I turn the Pi on for the first time, all the LEDs _DO_ light up until the boot progresses and then they shut off after a moment.
Any help on this is very appreciated!
