I recently bought the SiRF 3 GPS for my FEZ Mini. I want to get the specifications on the device itself. I am curious to know if it is weather proofed. I see that it has magnets to attach to the exterior of the car, but what temp and humidity can it operate at?
Thanks
Found all these specs on Olimex website.
MOD-GPS GPS SIRF STAR III MODULE WITH INTERNAL PATCH ANTENNA 2 METER CABLE AND UEXT CONNECTOR
INFO:
We have evaluated about dozen of different GPS receivers before selectiong this one and we found this to be the most sensitive and with the least power consumption of all devices we tested (Mstar, Skytraq etc), we found that SIRF STAR III chipset allow satelite tracking even withing buildings and with the only 38mA power consumption this device beats all other we have tested.
