HW version of Nano PI for gateway implementation

[queifaro]

Hi All,

i'm in plan to build a mini gateway using Nano PI.

I need the following:
5 serial port (standard serial or usb to serial) + console/debug port
WiFi interface (station and ap)
host usb port for LTE modem
RTC
256 MB DDR RAM
Some Linux distribution (for example Ubuntu core 16...)
Application firmware using C and or Java and or Phyton/miroPhyton

Application is i/o intensive and need to use some ciphering algorithm.

What HW version of Nano PI and WiFi interface can you suggest to use ?

Thanks in advance
B/R

I'm using a nanopi neo air in AP mode for WiFi and there is a RTC. There is an uart configured for Linux console.
