i want to ask what is the standard connection must connect to uno since this shield has a lot of pin
If it is a shield, it simply plugs in. Why are you not simply plugging it in?
because in the datasheet there are lot of interface like gpio,uart,iic &pwm,debug_port..i just cant understand it...do i need to connect all this pin..
Post a link to the device in question.

here sir
It's a shield. It fits exactly one way. When properly installed, all the required connections are made.
