XBee shield + Arduino WiFi Rev. 2

Wireless & IoT Other Radios
1

Hi,

Since the Arduino WiFi Rev. 2 has a “spare” UART (Serial1) I, today, use this for my XBee shield. It works fine. However, I would like to know if this setup can’t harm any components (XBee radios, XBee shield)?

Thanks.

Hi again Guy,

As far as I can tell, using Serial1 on the Arduino WiFi R2 should not harm any devices that have their own firmware on them. It is not attached to the USB interface so they are not affected by uploading/boot up data that could potentially corrupt an attached device. It looks like just a dedicated serial port so you should be just fine using that with XBees. You may want to double check by reading through Arduino’s [Getting Started Guide for the WiFi R2 but from a brief look, I did not find anything that indicated the possibility of harming devices connected to that UART.](https://www.arduino.cc/en/Guide/ArduinoUnoWiFiRev2)

Thanks for the confirmation.
