Hello
I’m using a pixhawk1 version 2.4.8 with the latest firmware.
I have an issue
Powering up the pixhawk via the power connector using the BEC / current sensor the board voltage is roughly 4.2 to 4.3 volts, a measure with a multimeter on the connectors pins I read 5V
This happens with two different boards that work well.
Clearly I needed to switch of the Arming Safety option for the board voltage.
Check the Pixhawk schematics and the voltage ratings. The +5V (or more) on the servo pins goes through diodes and IC’s to reach the measuring point and the 3.3V converter towards microprocessors, so voltage will drop slightly.
Hello,
I did these checks for voltages using a multimeter on power connector (attached image for pin out)
Pin 1 and 2 : OK, 5 Volts
Pin 3 : 0V its ok , no current is running through the pover converter
Pin 4 : 1.5V , this value is OK ? I don’t know
Pin 4 and 5 are the reference GND
Then I tried to power up the system via power module using a 4S lipo
the valure for Board Voltage is
