Gms-hpr GPS Module

Gms-hpr is compatible with its predecessor PA6B, offering you not only the same ease of integration like before and small footprints, but also utilizing the GPS chipset “MT3339”.

Gms-hpr features low power consumption which is 45% less than PA6B. It is ideal for use in small-form factor device design and can be integrated easily with maximum degree of flexibility.
