    Dr John

    I am considering running the crumble motor driver chip (Texas Instruments DRV8835) with a higher voltage (9v) on pin 1 (motor voltage input VM ) than is provided from the crumble power.

    This is an attempt to get faster motors for the drag race.

    We have done this successfully on other robots using the L293D chip which is similar.

    Can you pass on any hints or tips or suggestions? The data sheet suggests a 0.1 microfarad capacitor minimum. Thanks.
