Hi,

It looks like you are powering the unit from the UNO.

That unit is capable of consuming 1.3A when operating, you need a separate supply for it, do not use the UNO 5V pin.

Read the sheets you have posted.

nope, i am powering the unit from the same source of arduino, an external power supply 7,5v 2,1A
