I have a pretty similar issue,
Pi3 + Unicorn HAT
curl -sS https://get.pimoroni.com/unicornhat | bash
sudo python ./simple.py
and nothing coming out the LEDs.
I’ve sent my details to customer support, but in the meantime (given it’s Saturday and my excitement of the visual delights is still high) was there anything that might bring this HAT to life? Is there anyway to check whether the HAT is plugged in OK, to run any diagnostics on it, or check whether the HAT has been picked up by the board? When I do these commands above without the HAT installed I don’t get any errors either so doesn’t look there is a check going on to verify whether it’s installed before proceeding with the example.
@pinkkis - Did you get a new board and did that work OK for you?
