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

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