Sparkfun confirmed the shipment of the product the august 4 and I received the order tracking for USPS the august 6.
Untill today (august 20), I have not received the product.
The post service in Brazil is a mess and the customs have too much work.
I hope they don't charge me this because, here, the governement charge 60% for this kind of product plus 8 to 12% over this total (federal and state's taxes).
The tracking number provided by USPS is just to make you happy but it's useless (untill today, at their site, using my tracking number, they show only the status as "Electronic Shipping Info Received").
