AURT flashing stick got delivered today so i tried it with my little knowledge.
I connected 5V to the only unlabeled pin.
At first I got errors but, rather quickly, I figured out I needed to put it in “formatting” mode.
Didn’t know if IO0 had to be pulled high or low for this but a brief Google search got me the answer.
Using my breadboard to extract GND to multiple points it worked like a charm.
Remote flashed succesfull and the only thing I had to update was the MAC address in WLED settings.
