Hi Ladies and Gentlemen,
I recently bought two 20X2 and two Xbee modules. I created a 3.125v voltage supply and ran the X2's just fine with it. I also powered up the Xbee modules which showed an LED attached to the power on pin as working. The 20X2 has an internal LDO correct? Is the 20X2 all internally 5 volt logic or is it truly a 3.3v? If its truly 3.3v then I can connect the pins between the Xbee and the 20X2 without voltage dividers correct? I searched around a while and read some manuals, but still not sure and didn't want to damage a device.
Thank you,
Doug
