Just a few ongoing notes on building a reset switch for some of the Oranges. Currently unplugging the unit, or turn the surge protector on and off, is the only way to restart the board after safe shutdown. A surge protector with individual switches is a cheap and easy solution if you have multiple boards, but I was still curious about the possibility. I originally thought it was not possible, but now I’m unsure.

Orange Pi PC 2 Reset Option Schematic/PCB

Going to the PC2 schematic, there is a RESET-Option indicated under CPU. Q9 is located between the IR and AV ports. There was a discussion about this.

Also look at AR100 and related Armbian forum discussions.
