Can you pull the open collector outputs on the 6533 Digital I/O board to 3.3 volts instead of 5.0 volts? It seems from the specs that 3.3 volt inputs will function properly, anybody have experiance with this?
Logically, 3.3V would work since it is still a high TTL speaking. There is no guarranty though since the board was built considering that those pins will use 5V.
