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

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.
