In my sojourn through Tom Igoe’s book, Making Things Talk, I came to the Lantronix Xport.
The book says to connect the Xport Vdd to a 5V source, and page 119 shows it connected directly to the output of a 7805 regulator. However, Lantronix’ site and everywhere else says the Xport needs 3.3V. Ref: http://www.lantronix.com/pdf/XPort_DS.pdf page 4, where it says Vcc should be 3.14, 3.3, or 3.46V min, nominal and max, respectively.
Is the Xport capable of running off 5V after all? Any info appreciated.
Thanks in advance,
