DroneNet for Ardupilot with Matek F405-Wing

Hi,

I’m planning to use DroneNet for Ardupilot with a Matek F405-Wing V2 flight controller (STM32F4, ArduPlane 4.6.3).

I’ve read through the ArduPilot documentation for DroneNet, and I noticed it’s described as intended for H7-based autopilots without native ethernet support. Since the Matek F405-Wing is an F4-based board (also without native ethernet), I wanted to confirm:

  1. Is DroneNet officially confirmed to work with F4-based autopilots like the Matek F405-Wing, or is H7 a hard requirement?
  2. If it does work, is there anything different about the setup (UART port choice, PPP configuration, etc.) compared to the documented H7 examples?
  3. Given that “many features are currently unimplemented” per the product page, can I confirm that basic Serial-to-Ethernet conversion (for Mavlink telemetry over a companion link) is stable and production-ready on F4 boards specifically?

Context: I’m building a fixed-wing ISR UAV and want to use DroneNet to bridge Mavlink telemetry from the flight controller to a Teltonika TRB140 LTE modem over ethernet, replacing a Raspberry Pi + USB-ethernet setup due to current RPi Zero 2W stock shortages.

Thanks in advance for any guidance.
