As for the SD card, you need to find a high speed one with at least 8GB memory.  The system itself takes about 8GB, and high speed will avoid issues like system failure. That’s why we use EMMC chip on our KP3S Pro V2 and KLP1.

Just choose the img file and the SD card, then flash it. Once the process finished, put the SD card into the Orange pi Zero 2. You are ready for the next step.

Connect the pi to ether net and power supply, then you should be able to find the device in the router’s dashboard. It usually named as “Orangepi Zero 2” or “mainsail”. Then You can use the IP address to enter the SSH.
