I need some help getting this thing to power up. I am on my third Nano with none of them illuminating a single pixel! The first two were RMA 'ed and I am afraid the third one is junk as well.
I am using the the Adafruit 5V4A power supply recommended and have set the jumper J48 to the correct position. I get nothing. The green power LED is illuminated, but that’s it. USB keyboard mouse or not, no difference. I have an ONN 128GB microSD card installed and have formatted it as exFAT and just straight dd dump of the image to card. No difference.
How would I connect a serial port? From the documentation, when J48 is set to take power from the barrel jack, the mini USB port should function as a serial console, but I get no data from the port. The system it is connected to does not see a USB device connect/disconnect. So how are you supposed to get serial data. Please do not send me links for the older style board, with a single camera port; mine has 2 and no serial port header located near the camera port.
