Whilst I was waiting for the USB On-The-Go cable and Micro HDMI adaptor to be delivered, I tried one of my original Pi SD cards – but didn’t see any LEDs when powered up. One key difference on the Pi Zero – it has an activity light but no power LED. It also needs the most recent firmware upgrade to boot a Pi Zero, which is why I didn’t get any indication on power-up. A quick
rpi-update on my original Pi, and it boots nicely.
Now what should I use for my first project? Mono seems to have made big jumps since I last played with it, so I may see if I can use it to run some C# code.
