The PIC 18F1320 has 5.5 volt max. input, but the pressure sensors have a 5.2 volt max. Think I'll return the 5 volt wall warts to Digikey, and order a 6 volt switching or linear wall wart, and change the on board regulator from 7805 to a LDO LM2930T. The board is going to fabrication (quantity 3 or 4 to include spares to last a long time) with space for the TO3 regulator and a wire hole for direct 5 volt. Comments always appreciated. :) -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
