Further question on the capability of the motor outputs:
Can I connect a 1.5v single cell battery in series with the output to get a faster motor speed?
I have done this successfully with other robot designs, and therefore use a negative output to actually stop the motor.
To put it another way: Is the output driver a simple transistor bridge (like L293D) or is it a pair of amplifiers, capable of producing a low impedance output at all voltages?
I can just read the letters embossed on the chip, but can find no data on it. Thanks
