XBee Pro and Arduino Nano Current limitation

Other Hardware General Electronics

Hi Guys,
I'm running an Arduino Nano with a XBee Series 1 (which needs up to 50mA) using the circuit in the attachment (without the LEDs) and everything works.
But I want to increase the range, so I ordered a XBee PRO Series 1. Which might need up to 150mA when transmitting.
So I'm not sure if I will burn my Nano, am I?
Who did already use an XBee PRO with Arduino? Using which circuit?

Here it says:

DC Current per I/O Pin 40 mA

But here it says:

The sum of all IOH, for ports C0 - C5, D0- D4, ADC7, RESET should not exceed 150 mA.

RX and TX are Pin D0 and D1 in this schematic. So it should work with 150mA.

As they say:

Absolute Maximum Ratings
DC Current per I/O Pin ............................................... 40.0 mA
DC Current VCC and GND Pins................................ 200.0 mA

The 3.3V output from the Nano should be ok with the 150mA, right?
Let me know if I'm complete wrong with these interpretations!

I don't think so.
3.3volt power from an official Nano comes from the FT232RL chip.
AFAIK it's capable of supplying up to 50mA.
A Nano clone with a CH340 serial chip hasn't got a proper 3.3volt power output.
