I'm not having a 3 yet, but at least on average the power consumption is
not much higher, looking at the various published measurements. The
reported problems likely are related to higher or faster transients and

Yeah, it is the Pi3 that is causing people problems.

Now how can I avoid that? The Pi has no off switch!

I've been running my 2B unit on a 1A charger and never had any problems.

I put a couple of heatsinks on some of my Pi’s, (the one outside, etc.), but
they’ve never been needed based on it’s internal temperature sensor. This

Another quick note regarding power & the Raspberry Pi B+, 2 & 3 - the red Power
LED will turn off to indicate if voltage drops below 4.63V. The Pi MIGHT
continue to function Ok, but this is a clear indication of a power issue.

Something that is likely to be accurate. It will cost more than $5.
I have a Fluke 112. I got it because we had one at work and I liked it.
It's old enough that they don't make them any more. I'm not sure what I
would get today.

Thanks. That could be the problem. Meter says 4.8V. I didn't get out a
scope to look for dips below that.

I have had no issues with a GR-601W on my Gentoo/Pi3

Good point. This does sound like the kind of problem they get from dirty
or weak power.

I haven't tested with a USB GPS yet. I might get to today, but I have machines
to set up first.

That didn't take long. The 601 just hung on the Pi-3.

I've seen it a few times.
The symptom is no output. cat /dev/ttyUSB0 never prints anything. Neither

I haven't seen similar troubles with 601Ws on Pi-B or Pi-2.
