Do you have a datasheet?

It looks like it uses the L298n so should be very similar in operation.

I can't see any labels on the connections on the image, are they labelled? If so, what are they labelled as?

Pure guess work based on the L298n, I'd say that; The 2 connections on the left are Motor 1 +/- The 2 connections on the right are Motor 2 +- The 3 connections on the bottom are VCC, Ground & 5V (however the order is unknown without labels, datasheet or tracing the tracks). The pin header are your inputs/enables (in1, in2, in3, in4, ena, enb)

If that's the case then follow the L298n tutorial I wrote and adjust it to suit your board.

The jumpers connect Ena to 5v and Enb to 5v. Remove the jumpers, connect a digital port to ena, connect a different digital port to enb and use PWM on those two ports to control speed. Make sure you don't connect the +5v pin from the ena/enb to the EZ-B though.

To be honest, and I may be biased, but my tutorial covers it all in great detail and may give more of a clue than DJ's video.
