Re: MAP sensor circuit

Post the details! Provided they are linear, accurate and 5V it doesn't matter to me :-) Any can be supported in software. How hard to get are the bosch ones though? If you provide a part number I'll tell you if I can get them here and NZ, if not, the freescale might be the best choice just for avai...

Re: Connector considerations

Some other benefits include scalability. If you don't have a connection, you don't need to put it in. My snow blower isn't going to use 37 pins. However, I'm also sure there are folks that need more then 37 pins. Some other thoughts, the power and inductive loaded devices should have a connector th...
