Still trying to find my blueprints for it (I think its on my Ubuntu box, but my monitor is fried on it, grrr, and I'm sure its not accessable on FTP, I'm on my Windows 10 workstation now), but here is an interesting example of MOSFET motor speed control via GPIO or PWM.

However I would do it via UART or software instead. However the rest of the circuit is a great example of real motor speed control using an inexpensive MOSFET driven by MCU or BBB PWM.
