Greetings; I have now spent several hours doing google searches, looking for a chip that would be the reverse of a max232, so I can power this ttl based sparkfun thing from what is available from the serial port. There appear to be hundreds of variations on how to get from 5 or 3.3 volt powered motherboards to a serial ports voltages, but nothing to reverse that short of find an old ball mouse at a flea market and stealing the chip out of it.
Unforch, I have attempted to look some of those chips up if they were marked, with zero luck. Most of that stuff was never a JEDEC registered chip design it seems. Am I going to need to invent what should be just another wheel? Any chance there is a ttl level serial port on a header someplace on the D525MW boards?
