Power supply

1

First off I can’t thank everyone on here enough for all the help, and the generosity of providing all this for free, blows my mind.

Anyways, I’ve been using Ardusimple rtk2b base and rover for years, I’ve also killed 3 boards now. I’m not sure if they’re bricked but I can’t revive them. Ardusimple thinks my supply voltage is hurting them so I was wondering what guys are using, I run older machines that don’t have the voltage control of newer machines.

Currently I’ve been running a 12v to 120v inverter and then plugging my tablet and a powered usb hub into that. I then plug my rtk2b board into that powered usb hub. Anyways the collection of boards on my bench make me look smart but it’s getting expensive lol. Have a great day.

Well all the AOG modules can handle 12v. So I am powering them off the battery. And then bought a car charger for the tablet. Never need to get to 120v then.

The power of a dynamo is 14V. Thats a little higher.

The usb hub should be quite stable plus the simplertk2b also regulates the USB 5v down to 3.3v.

Don’t mean to reopen old topic but it seems to fit well here. Had a usb hub powered by a 12-30v to 5v convertor, however seems I overloaded the dc-dc convertor and on failure it shorted the 5v output line directly to the 12v-14v input taking out my hub, a teensy board and an f9p as well as leaving a nasty burning smell in the cab. Fortunately it was fused on the 12v side and blew the fuse but the damage was done!
