Hello, I am building a hub to check the voltage and current of sensors, pixhawk and computer hardware (jetson nano or rassberypi) and of course my engine, and send the values to the ground station using a telecommunication pack I designed. but my challenge:
I want these values to be sent to the pixhawk in addition to being sent by my board
But I did not find a safe way
I can’t use the voltage current sensor module, my current choke will reach 140 amps in an instant, so those sensors won’t be able to handle that current.
I have seen that my pixhawk 2.4.8 power port has a voltage data check wire and a current data check wire, but should
1 Is it enough to just give the output of the current sensor to that wire?
and for voltage
I don’t know what combination of resistors to use so that I can give the desired voltage to the pixhawk, because if I increase my maximum voltage of 14.3 to 3.3 with the combination of resistors, the pixhawk may recognize it as a 16V battery.
Or should I use mavlink or mavros?
I am using STM32F030F4P6 core
And I use ACS758ECB-200B for current sensor
