I have an Adeept Robot HAT, but the Blue Robotics BlueOS works natively with the Navigation hat (it’s probably pedantic, but neither of these two hats meets the requirements of Pi Hats). I was looking to see what the functionality of them both was, and ended up making a back-to-back comparison. The Adeept Robot Hat has fewer built-in peripherals, but the BlueRobotics Navigator Drone Flight Controller Pi Hats are a bit more expensive.
This is a quick back-to-back analysis so that I can now work out how to make a configuration file for BlueRobotics’s Blue OS to use the Adeept Robot Hat.

Further details should follow over the next few weeks of how I got on mapping the Adeept Robot Hat to the Navigation Raspberry Pi Hats configuration
