This is a small introduction to setup orange pi one
Format and prepare SD Card
Prepare 32GB SD Card, thus Orange Pi One can boot from up to 32GB SD Card. I am using SDCard Formatter,
Install Linux image on SD Card
Download image, e.g Debian Buster based version from https://www.armbian.com/orange-pi-one/.
Use e.g. Etcher to flash linux image to SD Card:
First time boot
Insert an SD Card into Orange Pi One and connect power supply
