Connect to Neo Air (or anything really) over serial. On a windows machine.

For Windows:

  • Download and install Putty

  • Connect your USB to UART adapter from your computer to your Nano Pi Neo Air (or any COM device)

  • Make sure you connect TX>RX and RX>TX (Sending/Receiving), otherwise both your devices are talking at the same time and neither one is being heard.

  • On Windows OS, pull up the Device Manager

    • Run Windows (WinKey+R) and type in devmgmt.msc


  • Find COM Port Number

Under, Ports (COM & LPT), there should be only one item which has the COM Port number listed in parentheses at the end.
In my case this is COM5


(COM & LPT drop down menu doesn't appear unless you actually have a COM device connected)

  • Establish Serial Connection:

In putty, choose the "Serial" radio button. Type in 115200 under speed (aka BAUD rate) and type in your COM Port number into "Serial Line" and then hit the "Open" button

At this point you may just see a black window, that's likely because the device has already booted and isn't printing to the serial connection. If this is the case, try simply hitting Enter, or typing something, and it should change the terminal.

Simply plugging in the device again, re-opening the serial connection before it boots up all the way, should result in being able to see the boot sequence whiz by, ending with a login prompt.
