Hi. I'm looking at a tank-track chassis that
comes with motors included. Are they suitable
for being controlled by a Blue or should I use
an external motor controller? For what it's
worth, I'm looking at powering the Blue with a
1600mAh LiPo battery.
Here are the details of the motors:
Operating Voltage Range: 3~7.5V
Rated Voltage: 6V
Max. No-load Current(3V): 140 mA
Max. No-load Current(6V): 170 mA
Max. Stall Current: 2.8 A
Thank you. My apologies if this query is
miscategorised.

You should be in good shape. The Beaglebone Blue
has a Toshiba TB6612FNG chip for the motor driver.
You should be below the average current spec
unless you are planning on have a huge load. The
stall current does exceed the spec, but it is
protected from thermal overload and will simply
shutdown. You software should also check for a
stall and turn off the drivers anyway.
