Hello everyone,
I wanted to ask some advice about the model of Arduino:
The project I'm working is a device with lithium polymer battery, that can "log" data received from GPS on the card (micro SD), temperature sensor and will probably ANT receiver, to receive data from cardio-freq.
What model do you recommend?
P.s
Do you have any advice regarding receiving ANT? What components i can use?
Greetings and thanks
The cynic in me says get an old Duemilanove or clone from Ebay, the official answer is a Uno 
You won't need the extra resources or expense of the Mega and the Uno is better supported than the Nano, Pro etc etc.

Hi, thank for the answer but for this device, the size matter, i want the smallest possible.

Is that in your original post?
Maybe you should produce all the requirements and then ask for help. If you don't know what you need -- considering the cost is less than $100 for most models the simplest solution might be to "buy and try".
In any case buying a UNO model to prototype and then moving it to a smaller unit might be the simplest approach. iow -- prototyping...
I saw all models, maybe the Arduino Fio is the better product for me, it has the lipo charger inside
Teensy boards are even smaller:

You do have to mod it to work with 3.3v by adding the 3.3v regulator for
an extra $1.
