I am looking for a gadget that can switch between the PWM inputs of an RC controller or that of a micro-controller. Ideally, one would activate the switching through one of the RC controller switches.
Other folks have suggested that this multiplexer could do it:

...combined with an RC controlled "switch" to activate the "S" pin for control.
Is there another way? Does Adafruit sell anything like this combination, or another solution to do the same thing?
Thanks,
Val

Re: Switching PWM Input Between Sources
There are lots of options for that, and choosing one depends on the details of what you want to switch.
If you have multiple PWM channels that come from two possible sources, and you want to switch the all the channels from one source to the other with a single control signal, the 74x157 is probably the most convenient option.

Thanks!
Seems like this kind of thing might be useful in an Adafruit breakout board product! It is a not-uncommon need for all kinds of projects, not just RC control. (my 2 cents!)
