      <div>This is where we could benefit from
        the experience of the robotics club guys (TAR - Triangle Area
        Robotics).<br>
        <br>
        You will want to power the teensy on its own, not through the
        power pins on a R-Pi.<br>
        <br>
        Circuit Cellar Magazine last August & September published a
        Raspberry-Pi I/O board that is far superior to the Gert Board
        and its like, but its shares one basic element:<br>
        <br>
        They have their own power connector, and regulate that with a
        switching 5V regulator and a separate 3.3V regulator.  That
        latter they connect to pin-1 of the GPIO connector to power the
        R-Pi - the USB power is never involved.<br>
        <br>
        If you are not using the 5V supply for anything beyond the
        motors, consider this 6V regulator instead (<a href="https://www.commonsenserc.com/product_info.php?products_id=51" target="_blank">https://www.commonsenserc.com/product_info.php?products_id=51</a>) 

        -- that'll get you more torque out of your motors, and constant
        voltage regardless of the battery level.<br>
