Thanks for the info. I connected a standard ardupilot-type voltage and current sensor to the PWR Sensor port , and it works after configuring the appropriate settings in the system tab of Libre pilot GCS.
One thing that bothers me during bench testing in the past week is , after I flash the Revo board with an Ardupilot fw, can I do ALL the configuration in Mission Planner, instead of going back to LibrePilot GCS ?
An example is the Battery monitoring. Can I configure the voltage and current sensor in the Optional Hardware tab of MP ?
My Revo board is running on the original Revo FW now. During flashing back and forth between Revo FW and Ardupilot FW of my other Revo board, I damaged one solder point of the 2 SBL solder spots before I started to solder an ON/OFF switch across the SBL solder spot to avoid soldering and desoldering on the 2 spots. That is why I want to make sure before I flash the Revo board with Ardupilot FW, I want to do all the necessary configuration which can only be done with LibrePilot GCS.
Appreciate your opinion and Happy New Year.
