Hi there,
I've been watching the schematics and specification/datasheet from the Teensy 3.1, and I have two questions about the voltage output and ADC Input
Q1
The USB input gives a 5V Out, I figured out that there is a 5V output line.. actually two, but one out(VIN) can be used for external voltages.
For my project i need 5V Out, but is this line (VUSB) protected when the circuit accidentally shorts? Because I don't want to destroy my USB interface on my laptop.
Q2
My measured signal (sensor output) has negative voltage output(± 5V and/or ± 2.5V). Can a negative voltage be measured in the single/differential mode? Or do i need to lift the voltage to a positive range?
Friendly regards,
Klaas
