I have received my Atomic Pi, but upon connecting
- Display via HDMI cable
- a Keyboard via USB port
- 5V regulated power supply via pins 3,5 (GND via pins 2,4) nothing happens. Nothing comes up on the screen. I've double checked that the monitor is working and that the HDMI cable is good. Should there be an LED on the Atomic Pi that lights up if it is receiving power correctly?
