Introduction

This Grove - GPS module is a cost-efficient and field-programmable gadget armed with a U-blox 6 compatible GPS module E-1612-UB and serial communication configuration. It features a 50-channel U-blox 5 positioning engine which boasts a Time-To-First-Fix(TTFF) under 1 second. The sensitivity of tracking and acquisition both reach up to -160dBm, making it a great choice for personal navigation projects and location services, as well as an outstanding one among products of the same price class.

Model:SEN10752P

Features

Grove compatible interface
Supports NMEA and U-Blox 6 protocols.
Low power consumption
Baud rates can configurable
