FEZ Mini provides pins with RS232 level.
What is it the voltage ? (The voltage of the rs232 is it +/- 12v ?)
How is it possible if fezmini is powered by 5v (usb)
Another question, on fezmini/robot there is a rs232 connector,
if I want to connect an xbee module, can I connect to it ?
xbee I think that requires 3.3v of power supply and signal.
If I connet it on the fezmini rs232 pin what happens ?
What the level on fezmini rs232 pin ? I need a converter ?
If instead use the pin: com2(UEXT3/UEXT4) , com3(di7/di8)
should work fine because they are normal uart ?
