I am going to attempt to run my TX2 plus carrier board dev kit from an 8.4V LiPo Battery (1Ahr, 20C). Haven’t tried it yet but I am assuming it will work given the TX2 input voltage range (5.5-19.6V). Trying to get some information beforehand.
My questions are for anyone who has tried this before.
Is the input power for the TX2 constant? What I mean is, does the unit pull less current at higher voltage and more current at lower voltage? Or is the current draw more or less constant regardless of input voltage level?
At what voltage level will the module start to shutdown or go to sleep? From what I can tell, the module is controlled by a “Vin_PWR_BAD#” signal from the carrier. What is the threshold of this signal transition from high to low? And can it be changed?
Appreciate any assistance provided.
Once I get my module up and running, I will amend this post to show my results.
