Im new in this community, i just started using arduino m0 pro and i want to connect it to internet by using sparqee for my final year project... the problem here is since operating voltage for m0 pro is 3.3v while sparqee is 5v, i want to know if the voltage from sparqee affect my arduino or not, since after i connect sparqee to my arduino, the arduino cannot upload sketches...im afraid if my arduino is brick since the power is different.. i connect the arduino m0 pro and sparqee by using arduino shield... thank you for your knowledge..
The SparqEE CELLv1.0 device.

You're fine. Since the Arduino and CELLv1.0 both use the serial lines, you do have to disconnect it to upload sketches. Since the Uno only has 1 HW serial UART there was really no getting around this.
