You are fine. Reset is no the issue. Power is. The fact that the power is
removed makes everything safe. Reset is an easy way to make sure
the board is powered up and provides a logic level indication of that fact..

On a related note: If my sensors are buffered and gated to sys_resetn am I
safe if the BBB powers down a few ms before the rest? My circuit watches the
3.3V regulator output and when it falls away the power for the entire circuit
is killed as well but it takes 5-9ms for the power controller to

I sure hope that was years ago when they actually won a game or two. We
have other attractions. We even almost have NASA.

Houston! Us folks in this part of the state try to stay away from Houston!
Actually I have spent a lot of time over the years in Houston. Been to a
few Astros games as well.

The way I read the manual and understand Gerald is that it isn't safe any
more than it is safe to play Russian roulette because you don't always get
shot. As Gerald said, you just might get lucky and not blow anything...
until you do.

Thanks Gerald. That is exactly the response I was expecting and exactly
the feeling I had. Never really like playing Russian roulette myself. Do
you see any issue with powering the sensors via a voltage regulator like
http://www.pololu.com/product/2098 that can be turned on via a pin on the
BBB
If everything is driven form the same power source, even with voltage
dividers or regulators, can we assume that turning on all devices at the
same time, with one power switch, is safe or do we need to somehow put a
delay into powering on everything but the BBB board?

I put that in there for a reason. It may not happen all the time, but
eventually you could blow up the processor.

As part of the Control of Mobile Robotics class offered through Cousera,
the students are building robots based around the BeagleBone Black. The
robot has 5 infrared distance sensors and 2 reflectance sensors used for
odometry. These sensors are connected via voltage dividers to pins 33, 35,
