    I got Buck Converter and working well, but have one problem….

    USB output should be set manually, first to push the “SET” to USB Mode,

    then next to push “ENT”.  I’d like to use USB output as default when

    turn on input voltage .  Is there a solution for this?

    Hello Takajin,

    Please kindly check if it is this item 180080

    Because USB output is not fixed 5v output, in case damaging your device, it is not allowed  to make USB output as default output.

    Best regards.

    Hi…Voltage at barrel jack from Drok buck converter is a steady 5.14 volts, using my Fluke DMM…outside is supposed to be negative inside is positive right?  Plugged in to Arduino the Drok buck converter supplies 3.83 volts at the back of i2c back pack as well as at 5V arduino plug and ground, Display no good.
    Using cell phone battery Voltage on back of i2c back pack is 4.89 volts….output testing at 5V arduino plug and ground is also 4.89 volts display is perfect.

    So disappointed….  I was very excited to find the 180080 and it is doing exactly what I need for my application when I set it to USB.   However, if I can not save the settings to use USB after a power cycle, then it is useless for me.

    Is there any way to save the settings?   Any options?  else I will need to return this…

    Thanks,
    Nick

    Hello Nick Triantos,

    We are sorry there is no way to set USB port as default output.  That is for prevent damaging your USB device , because USB port is not with fixed 5v output.

    Best regards.

    Ehi raga! Scorrendo Instagram a Roma mi è capitata la clip di Gates of Olympus con i tumble a catena. Ho messo 100 spin a puntata bassa, intervallati da micro-pause “espresso e respiro”. A metà ho salvato duospin per usare la stessa griglia domani senza pensarci troppo. All’inizio poco movimento, poi un 100x mi ha riportato dritto sopra lo start. Non ho alzato lo stake dopo il colpo: ho preferito chiudere sereno. In Italia la sera è corta, meglio tenerla leggera e senza tilt.

    J’ai trouvé ce site via une recherche sur les meilleurs casinos en ligne. En testant Spin Granny, j’ai tout de suite accroché aux jeux de poker. J’ai aussi passé du temps sur les slots online avec beaucoup de succès. J’avais perdu un montant important, mais j’ai fini par tout gagner en un seul soir. Je suis pleinement satisfait de cette victoire. C’est un divertissement solide pour les joueurs installés en France.

    <span data-sheets-root=”1″>People love sharing photos that show culture style and happy daily moments. Instagram posts look even better with captions that match the feeling of the picture. Many users enjoy writing simple lines that show pride in their background. That is why many search gujarati captions for instagram to add local flavor and personality. A caption in Gujarati can make a post feel warm friendly and unique. It also helps people connect with others who love the same culture.</span>
