we are two guys from italy working on a drone for our high school final project.
Right now we are working on the ardupilot telemetry, and we have a question:
In the original project the Adafruit adapter board is used to reduce the signal voltage from 5 volt to 3 volt, and the xbee power in could be connected to the Ardupilot`s 3.3v out, right?
Now, i do read in the Xbee modules datasheet:
Serial Interface Data Rate:
(software selectable) 3.3V CMOS Serial UART (5V tolerant UART)
Does this means that i can connect the xbee directly to the Ardupilot without damaging it? Ardupilot can provide to the xbee 3.3 volt power source, so no problems here, and the xbee module can tolerate the ardupilot`s serial out signal voltage, right?
cheers
