You don't have to add extra filtering room for auto stuff - it could be external. Just wanted to make the point that the wide power supply input would come in handy. Could be something run off a solar panel and battery for example. -----Original Message----- From: Olin Lathrop Sent: May 19, 2005 2:40 PM To: "Microcontroller discussion list - Public."

Hmm. It costs money and board space to protect against the nasty spikes. I'll look into leaving pads for an alternate 12V automotive power input. This would have a series diode with either a series inductor or resistor followed by an active clamp that clips to a bit under 30V since the rest of the circuit can already handle that. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
