RE: L298 Motor Driver from Open-Electronics.org and the BeagleBone Black/Python...
The board can be found here: https://store.open-electronics.org/robotics/electronics/L298DRIVER.
The BBB, BeagleBone Black, can be found here: https://beagleboard.org/. The BBB and other variations can be found online and w/ an easy google search.
I have some basic software, some leads, and the connections are made from the BBB to the L298 motor driver. I am using Adafruit_BBIO library which can be found here: https://github.com/adafruit/adafruit-beaglebone-io-python.
Python 2.7.x is what I am using to type up the software.
