There's much to like in the new Beaglebone Blue board. Along with the usual Beaglebone processing power and Linux support, it has built-in IMU sensors, good WiFi, proper connectors and (for rovers) motor drivers and wheel encoders. It's also just $79, and supports ArduPilot out of the box!
But before you toss your RasperryPi 3/Navio 2 combo (which is awesome but costs more than twice as much), here are a few things to keep in mind.
That said, for ground rovers I think it's a very interesting choice because of the built-in motor driver and encoders. I'm going to give one a shot.
