What you’ve suggested will work. Personally I’d be using a serial port on the Pixhawk, not USB. Also, powering a Pi over the GPIO bypasses the polyfuse. There are pads on the bottom of the Pi near the micro USB that you can solder 5V to.
So: I’d do it differently to be more robust, but your way is easier and will probably be fine.

Anyone knows about this~Thanks in advance
I have been wondered if I could find a way to output a constant 5V and adjust it to lower electric lever like 1v from main out pin or Aux pin in Pixhawk(using rover), already check the docs and find out I can use main out to output PWM or Aux to output an instant high/low level, they will act as a signal for controling other equipments,
The DJI rover stuff. Not actually new, just hasn’t been marketed to consumers before
Hopefuly with some "openess" of the underlying protocols ;-)
I noticed in the docs that dodge does not work with the 360 degree lidars and I was hoping to be able to use it for obstacle avoidance on a survey type mission.
PX4 flow sensor is not working in Pixhawk 4's I2C A port. Any idea?

Hi, I'm confusing about how to power a servo with pixhawk 4.
I connected the signal to OUT7 and +/- to a BEC and didn't work.
Then I connected the negative of the servo to the negative bus of pixhawk and smoke appears on the servo :(
Here is a wiring diagram:

Hello, I am switching my hardware to the cube black. I've read on the forum that bulletin about some trouble with some versions of hardware. I wanted to hook it to mission planner and see if it says the warning. So far it hasn't throw it but I am not sure if it is because I've uploaded a firmware built from source. I used BlackCube target on waf, is that correct? I noticed also CubeBlack+. With arduplane built from source mission planner doesn't give any warning. I've tried to upload the firmware directly from mission planner but somehow it doesn't detect the board. Should I be sure that my hardware is not affected by that bulletin? Thank you very much.
i have a pixhawk1 with a broken off usb connector....I am unable to update ardupilot releases. I have tried hooking up via the USB port pin output (vin, d-, d+, g) and none of my linux or windows PC detect it....i try flashing via serial port using an USB-TTL converter and no luck either....i was wondering if I can flash the latest ardupilot hex via ST-LINK device? but I need to locate the proper pins (SWDIO, SWCLK)...is this possible?
Hello, I'm trying to port Ardupilot code to STM32F779.In list of supported hardware board i could not find this exact board. The nearest board i could find was STM32F777x.
Can anyone mention the list of steps that i need to follow to port my code to STM32F779?
Also please mention how to verify whether or not my code has been ported successfully to the said board. Thanks in advance..

My question is how Pixhawk4 could read it despite they have the same address (0x28H) and connected to the same i2c port(bus)

@syedhammadhussain - the core file you need to get right to do a 'port' is called hwdef.dat, and there is basically one of those for every port/board... as tridge suggested find something that is as clase as you can to your cpu type, and them adjust it . https://github.com/ArduPilot/ardupilot/tree/master/libraries/AP_HAL_ChibiOS/hwdef
... and my guess is that this file based on the 777 is the most relevant point to start from..

@peterbarker thanks that was the brand I saw many people had in ardupilot devs and I did not know that they do discount for students. Has the Logic 8 enough sample rate ? I never used this kind of device but I think it would be very usefull to debug all my protocol programming
