It is possible to read from and write to terminal using UART pins. This makes it possible to setup Pi software without connecting display to it and without having it connected to LAN.

Step 5: Switch the Pi On
Connect +5V supply to the Orange Pi.
Step 6: Start PuTTY Session
Open PuTTY and set session (you have to select "serial", before filling in port and speed.
