Re: [beagleboard] Are these motors suitable?

[Przemek Klosowski]

Sorry, I didn't read your email carefully---you were talking about Blue,
which as Mark points out has power drivers that can drive motors, so forget
what I said below.

Thanks, Mark. That's what I was hoping to hear.

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.

Re: [beagleboard] Are these motors suitable?

[Przemek Klosowski]

Beaglebone can source few dozen mA at 3.3V so you do need to put some
controller to drive those motors.

[beagleboard] Are these motors suitable?

[renglund63]

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.
