The Big Idea

• Copy the Pixhawk’s functionality except:

  • a device with more compute for autonomy to do airside processing (an RPi 5)

  • support more CAN transceivers for our push to CAN infrastructure and remove all extra unneeded connectors

• Single Stack for the drone’s LV processing system to minimize assembly effort

  • flight controller would be a RPi hat

  • stack would be: RPI5 + LTE hat + anything we want + zp4

• Leave the HV stuff separate from this stack

  • this allows for us to do weight balance and wire length optimizations still and keeps our system somewhat flexible.

• This project is far out (as of May 2024)

  • We should wait for this to become more necessary as time keeps slipping into the future.

  • If EE has available to start now (or as soon as possible) we should because this is a large endeavor

  • As time goes forward we will get more new features and ideas so no point in the huge rush.

  • very similar idea, this is meant for ROVs so we’d optimize ours for our platform of course

Development

Implementation Details

• We need to be extremely cautious on the mounting of the IMU and barometer ICs as they are in the pixhawk

• We should pick the most powerful ardupilot supported microcontroller from the list (STM32H755 or something).
