On the back side of OPiOne PCB you can find also TVOut signal and MUTE which is used to disable audio amplifier but of course OPiOne has no such on board and even OPiPC had this unit removed.

Same way like above it is easy to expand OPiOne adding missing analog audio, mic and IR receiver.
1 - IR receiver RX line
2,3,4 - MIC1P/MIC1N/MIC-MBIAS
5,6 - LINEOUTR/LINEOUTR
Look at Orange Pi PC schematics to find out what extra components should be used to obtain full OPiPC functionality.

Orange Pi One PCB is designed to easy add almost all removed features from Orange Pi PC. Currently only RAM expansion is unprofitable.
To add 2 removed USB ports just solder wires to solder points as shown below on the photo:
Data lines for USB #3: points 1,2
Data lines for USB #2: points 3,4
Power can be taken directly from GPIO header or DC socket. OPiOne has no separate voltage regulators for USB ports like previous boards used to have.
This way I want to solder mini WiFi dongle (after removing the case and USB port) directly to the PCB.
