    cbm801 got a reaction from bozden in Orange Pi One - adding USB, analog audio out, TV out, mic and IR receiver   
    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.

    cbm801 got a reaction from emorysmith in Simple hardware terminal emulator/display for debugging booting issues   
    Maybe this is not strictly related to Orange Pi PC but a few weeks ago I had problems with booting my device - mainly OpenELEC and I had to debug it somehow using serial port and the terminal. Unfortunately my PC is rather far from the place where I keep OPiPC. So I was forced to prepare separate device - cheap STM32 MCU based terminal display with 2.2" LCD screen directly supplied from Orange Pi PC 3.3V. It can be used also with other devices which allow serial console debugging.
    Watch below videos for more details and the code:


    Maybe someone finds it useful.

    In my humble opinion it is not worth to save $5 and it's better to buy full OPiPC for $18.69. However for some simple applications like armbian server/NAS/home automation/etc OPiOne could be good enough. But for multimedia there are serious limitations. Most significant is memory - only 512MB. You can consider using only OpenELEC but still with some limitations. For example forget about 4k in h265 because OpenELEC uses too much memory and doesn't want to open such videos. Some plugins have memory leak issues (like YT addon). Forget about Androids - those for OrangePi need 1GB for comfortable use. Of course for analog audio you need to solder 2 very tiny wires which is rather difficult because it is very close to SoC and points are very tiny. Same for USB. It's not worth to save $5. Also I don't like CPU power management in OPiOne which makes it hotter than PC. I personally purchased One just for fun. And I love gadgets Maybe I will use it for multimedia, as OpenELEC dongle for one of my TVs. But only when jerney solves problem with HDMI-CEC support - I just want to use same remote for TV and multimedia. I don't need 4K, but YouTube can be problematic because it crashes frequently on One due to lack of memory.
    I also don't want to wait for Lite which will have same limitations and additionally no ethernet port. WiFi is not huge benefit because I can buy WiFi dongle for $1.7 which is less than $2 price difference between One and Lite.
    OPiPC is for sure most profitable buy currenly. I will rather wait for 2GB version of PC.

    Currently I want to share how to disassemble this dongle without damaging anything.
    Watch my short tutorial video:

    Using this module without the case significantly improves WiFi signal quality and range. Finally it would be possible to solder external antenna socket.

    Wow, thanks for bringing that to my attention. They recommend a heatsink for what they call "heavy processing (and H.265 is probably the heaviest use case there is, with use of multi-core NEON, plus vector GPU and QPU code running)". Ok, this is H.265 with Armbian 5.05 running on a cheap Orange Pi PC:
