    Elektrický reacted to djurny in Orange Pi Zero NTP Stratum 1 PPS GPS Server with Armbian OS, Hardware and Software Tutorial   
    Hi @Elektrický,
    Nice tutorial, worked great for me. Bought a cheap GPS module:

     
    And a pinheader to solder onto the OrangePi Zero board itself.

     
    The only thing I had to change was to swap the RX/TX wires, as a straight connection did not work for my GPS board.


     
    I did not have any success getting PPS to work through the USB connection (works as ttyACM). I had to use the GPIO dtb overlay and electrical connection as per your tut.

    Thanks a lot!
    Groetjes,
     
    p.s. I still have to figure out why I needed this

    This tutorial uses a 3.3V capable GPS module with PPS output - TOPGNSS GN-701 (u-blox 7) but other similar modules should work.

     
    This tutorial is for the Orange Pi Zero, but will probably work for other boards.

     

    I couldn't easily do a comprehensive hardware and software tutorial on this forum, so I've published it on my web server and linked from here and attached a PDF.

    Thanks @Guidol,  I had the same issue with Orange Pi Zero Plus. 

    One showed Cpu Temp And Cpu Frequency.  Two did not show the options.
    ~/.config/htop/htoprc was blank on the two that did not work.
    Changing settings on htop did not populate the file and settings were lost between sessions.
    File permissions were the same for all three.
    I copied the working htoprc to the other two and this solved the problem.
