Greetings, My buddies and I encountered a similar problem with the motor drivers. The actual specs on a single "Stock" motor driver is .5A . We needed a a driver to handle at least 1A, so we got the TI motor drivers. We found that stacking 2 TI (...) (25 years ago, 9-Sep-99, to lugnet.robotics.handyboard)

the car will almost undoubtedly fry the motor driver on the HB, and having it on the same power will probably generate enough noise to occasionally reset the HB. best bet would be to have the car use its own power and h-bridges, with the control (...)

First of all - get rid of the CAPS LOCK!!! Second of all, if your RC Car draws a Max Current of 3.5 Amps then you'll blow the motor drivers on the handyboard since they're only spec'd to provide 1 A. If the RC car starts asking for more current then (...) (25 years ago, 8-Sep-99, to lugnet.robotics.handyboard)
