Hi Fred

I am attemping to run two low voltage DC motors (as motors 0 and 1),
around 3V each(I don't have specs). I have piggybacked two of the motor
driver chips (and maybe adding a third) to handle the higher current but
they are still getting quite warm.

I would like to reduce the voltage supplied to the motors in hopes that
it will limit the current drawn and not heat up the chips.

Can the battery pack in the HB be reconfigured to supply half the
voltage without affecting the HB operation? and if so do you think this
might be a solution?

Thanks

  Re: Reducing Battery Pack Voltage
 
as has been discussed on this list, the Handy Board wasn't really designed for three volt toy motors. Reducing the voltage and doubling the motor chips is a reasonable approach, however. The Handy Board requires 7.2 volts to operate, because of the (...) (28 years ago, 1-Mar-97, to lugnet.robotics.handyboard)

U can use an external battery with the HB. It can be 3V. Check the FAQ in the HB HP.
