I am thinking of using the power module for a completely different application and so I have a few questions …
- The outputs are 5v @ 2.25A on VCC, I and V sensing. What is the purpose of the other wires?
- I assume that the I & V pins are analogue values corresponding with input V and current draw I. What are the input ranges? Documentation on ardupilot says max 18v and 90A - is this also the calibrated range.
- What is the analogue output range? Is it linear? 0 to 90 = 0 to 3.3V
- What is the resolution that I can expect on the measurements?
- I assume that the current flow is unidirectional - what occurs in a reverse current situation zero I? Is it blocked?
- What is the voltage drop across the input/output?
A lot of questions … maybe there is a spec sheet that I can use?
Many thanks
