GPS module based on MT3329 Mediatek with internal patch antenna 2 meter cable and UEXT connector
We have evaluated about a dozen of different GPS receivers before selecting this one. We found this device the most sensitive and the one with the least power consumption of all the devices we tested (Mstar, Skytraq etc). We found that MT3329 Mediatek chipset allows satellite tracking even within buildings and with the power consumption of only 40mA this device is better than all the other devices we have tested.
