Our most successful ultra small gps module with integrated patch antenna just got even better. For starters, parts of circuitry are tweaked and tightened for performance and characteristic enhancement. Then, a new patch antenna is finely-tuned and utilized, chosen solely for its ability to take the overall gps signal reception to the next level. This deadly combination provides a stunning sensitivity improvement across the board. Pa6b is completely pin-to-pin compatible with its predecessor pa6, offering not only the same ease of integration and small footprints, but also utilizing the latest gps chipset mt3329 from mediatek. You can instantly upgrade your pa6 based gps device by replacing them with pa6b.
