There are two versions of arduino nano???

Hi guys...Can someone tell me if the second version should work with my sensors?

Version 1

Version 2
http://www.ebay.es/itm/201722913123?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

i have 2 sensors with the first version and works very well, but now i by the second version and my gw dont detect my sensors.
Is there any difference

@conde
When you use the second version, do you have a fixed Node ID in your code?
When you start second version, do you see anything in your Log of controller?
If you don't have a fix Node ID, GW/Controller will give the second version a new Node ID which is not the same as first version, maybe that's why you don't see any data.

@conde From what I can see both of them are Nano 'clones' with with different serial-usb converters. Some clones get the 3.3v supply (what you use for the radio) from the converter chip. This is a weak (low-amperage) supply possibly causing the radio to malfunction. Also when a separate 3.3v ldo is used it can be very weak. As you notice there are many assumptions here. Possilbe solutions: add an extra capacitor to the radio power supply > 47uF -or- power the radio from a different power supply (ldo).
