Xbee digital Input/Output voltage

Hello, maybe the same sort of question, but do we just need a resistor to connect digital output from arduino to digital input from xbee ?
It's to use a PWM TLC5940 (or PWM Shield) with a xbee without a arduino.

Example :

  • At one side : Arduino digital output pin 9 and 10 to xbee DI input 0 and 1.
  • at the other side : xbee DI output 0 et 1 to TLC5940.

then control the TLC5940 wirelessly and with only one arduino.

So to connect the 5V digital output from arduino, to 3,3V DI input from Xbee ? what issues? Just resistor or regulator 3,3V?

Thanks a lot
