Hello, good evening. I’m writing this message to ask about the Pixhawk PX4 PRO
I am a Brazilian aerospace engineering student and a member of an aerodesign study group. I am part of the electrical team, and we are developing a power limiter for our electric engine. We recently purchased the PX4 PRO High Set kit and found the 3DR current/voltage sensor very interesting.
We would like to replicate the circuit board to incorporate it into our own power limiter (we are using an STM32 microcontroller). Our goal is to design a single PCB that monitors voltage and current, sends the data to the STM32, and then controls the PWM signal from the receiver to the ESC.
If you have the circuit diagram or datasheet for the 3DR Power Module, could you please share it with us? We would be very grateful for your help
