Hey guys, is there a way to display the info of two batteries? I’m using the main battery with the current sensor for the pixhawk and the electronics. And I have a second battery for the FPV electronics. I want to see the voltage of the second battery in the osd information.
If I remember correctly, the ADC pin senses analog voltage, so maybe that one could be hooked up to the voltage pin of a power module and transmitted. I’ve never done it though.
Just connect the voltage and current sensors to the 3.3V AD inputs or use a simple voltage divider. Caution: the input voltage must not exceed 3.3 volts. Set BATT2_MONITOR to 3 (voltage only) or 4 (voltage and current) and BATT2_VOLT/AMP_PIN to 13 and/or 14. Finally, you have to calibrate BATT2_AMP_PERVLT / BATT2_VOLT_MULT.
