MT3337 Antenna Integrated GPS Module SKM52

The SKM52 GPS module receives the signal through the built-in antenna, and the serial data such as position, speed and time information can be recorded completely through the nmea protocol or the serial interface custom protocol.

Chip MediaTek mt3333
Power Consumption 66mW
Dimension(L×W×H) 20*20*4.9(mm)

The SKM52 is a complete GPS engine module that features super sensitivity, ultra-low power and small form factor. The GPS signal is applied to the antenna input of module, and a complete serial data message with position, velocity and time information is presented at the serial interface with NMEA protocol or custom protocol.

It is based on the high-performance features of the MediaTek single-chip architecture, Its –165dBm tracking sensitivity extends positioning coverage into place like urban canyons and dense foliage environment where the GPS was not possible before. The small form factor and low power consumption make the module easy to integrate into portable device like PNDs, mobile phones,cameras and vehicle navigation systems.
