Recently I published an article explaining how to read and write to your NanoPi M4 or M4V2 digital pins from bash, now I’ll be doing the same from Python with the help of a few libraries.

In this guide you’ll find out how to read and write values to your NanoPi M4 or M4V2 digital pins also known as GPIO. This low level interface allows you to control digital electronic circuits directly from Linux.

NanoPi NEO 2 is a very cheap (15$) and very good single board computer featuring a 64 bit quad-core ARM CPU. The only drawback one might found is the CPU locked between 816 MHz and 1 GHz. Today I’ll teach your how to safely overclock your NEO 2.

So you got an amazing ARM SBC with the RK3399 CPU (NanoPi M4 / RockPro64 / Rock Pi 4B), so much power into such small form factor. Now you are trying Apache or other network intensive tasks and your network seems to crash randomly after a while or whenever it is under load? Learn what the cause of this common and how to fix it.

AppArmor allows you to restrict programs’ capabilities with per-program profiles. Profiles can allow capabilities like network access, raw socket access, and the permission to read, write, or execute files on matching paths. Learn how you can enable it in Armbian for a safer SBC.
