how to interface(pin mapping) arduino and sx1272mb2xas

i need to send sensor datas from one arduino to other arduino using sx1272mb2xas(transceiver).for this serial communication ,how should i connect arduino and sx1272mb2xas....must the sensors be connected to arduino or sx1272mb2xas(radio shield).

Heard of Google ?

Well if you do a Google search on sx1272mb2xas the first link is a page on the Arm website which has a very large picture of the pinouts.
