If I remember correctly these motors need 3-6V and less then 0.5A (but mini= mum=20 for the chip is 4.5V) so you must dissipate the heat because the absolute m= ax=20 power dissipation is only 2W, i think that a ground plane is not enough. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
