can i use adapter for receiving end without using it on transmitting end?

i m using the xbee s2c modules. i m building a quadcopter but it cannot take the weight of the adapter of the xbee connected on it. i m using an arduino nano and sensors and will be using a power distribution board. so do i need an adpater for this transmitting xbee?

unless the nano is running at 3V, you will need some sort of level shifter.

You will some source to power up this Digi XBee. If this distribution board can provide voltage between 2.1-3.6v (2.7-3.6v for Digi XBee Pro S2C) then it can be used.
