GRT Avionics

Greetings.

What is the minimum input voltage that the HXr permits? Curious if a backup battery I have on board would be sufficient.

Thank you.

On a 12V unit, 10 volts, and it will draw more current than at 12. Note that the analog input pull-ups run off a regulator from input power, and that voltage will change if the input power voltage decreases, which could affect sensor inputs that use the pull-ups.
