Sorry if this question exists in another thread...
I want to be able to use Brain 2 with external power and perhaps use USB simultaneuously. What happens if I connect USB while it is powered by an external supply?
I also want access to Vin "unregulated power" on the Brain 2 when using external power. I see where it's availble on Brain 1 but I don't see anything about it in Brain 2 wiki.
Lastly, what is the largest voltage power supply I could safely use with Brain 2 external power input?
I am considering combining FSR's as Brain inputs that are switchable for voltage control sources for Euro.
Thanks for any help!
