Hi there,
I recently assembled a Jetbot and connected to it, The camera works fine, but the motors don’t do anything. I checked the documentation, and it suggested swapping the cables around for the motors to the board, but that didn’t do anything either. I used a multimeter to check the pins that give the motor power, and it shows up as 1.49 V (which I assume means that power is going to the motor). I am trying the basic_motion.py file to have it move around.
P.S I am a noob at electronics; please forgive my lack of understanding of seemingly obvious topics 
The motor driver needs 3-11v to work correctly; try ensuring your wiring matches our guide https://learn.sparkfun.com/tutorials/as … in-chassis
What pins are you testing that show up @ 1.49v?
I’d recommend just running the 5v pin from the Jetson to the motor driver board, hooking up the motors as pictured
So I tried this, even hooked it up directly to 5v power from an arduino. It just refuses to rotate

5v power from an arduino.
An Arduino cannot power any motors, and can be damaged if you try.
A 4xAA battery pack should be sufficient for those motors.
Ok won’t do that again then lol. What I was attempting to do was to check if the motors work. They are attached to a Jetbot and the cables are set up as per the instructions, but they don’t rotate at all. Any guidance would be appreciated.
Test each motor individually by connecting the leads to a 4xAA battery pack.
If the motor spins, the problem is in the motor driver, motor driver connections, or the programming.
