- Relatively fast shipping - An OK build quality
CONS
- CC2541 does not have a USB interface - CC2541 cannot be used for a PC USB dongle build and TI RF Sniffer software. - CC2541 lesser output power when compared to CC2540 by +4dB
Ordered from FASTTECH on September 10, 2013 and received CC2540 as advertised. I liked the module and designed a USB dongle PCB around it. Reordered February 21, 2014 and received CC2541 instead. Contacted FASTTECH, after 4 days received a message that there's no difference between CC2540 and CC2541 and that I should be happy, though they will be changing the product description to reflect the fact that there could be CC2541 in the batch. I respectfully disagree, YES there's a difference between CC2540 and CC2541 and this is definitely should be noted as for instance in my case CC2541 is not very useful.

Cheap Fairly detailed documentation Got it working in a couple hours Manufacture's website has example android apps for serial and ibeacon
CONS
Documentation is written in broken english (still understandable though)
Works great. Highly recommend also buying the following breakout board. I soldered the just the relevant connections to the breakout board (vcc, gnd, rx, tx, led) which has an led to make it much easier to see if you are connected, etc.

Small Cheap good for soldering on board or wires directly
CONS
first order with cc2540 second order with cc2541
Have ordered 6 pieces of the module.
3 in November 2013 that had the cc2540.
3 in February 2014 that now have the cc2541.
The cc2541 needs less power, but does not have a USB-Interface.
