Nathan, the datasheet says you should I use ultrafast diodes on the outputs of the L298, otherwise it would be a junker almost immediately, even with the smallest of steppers For DC motors I always include something like an MUR1560 and a Schottky plus at least one filter cap right at the motor terminals Joe --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
