SkyTraq Venus838FLPx GPS Breakout Board

Overview

SkyTraq has introduced the fastest consumer grade GPS receiver available. The Venus838FLPx GPS receiver module has industry leading 50Hz update rate, very fast and accurate position/speed response, suitable for UAV, RC plane flight logging, and high-performance race car or speed boat data logging applications. When running at lower 1Hz, 5Hz, or 10Hz update rate, the Venus838FLPx receiver can be used as a typical GPS receiver module currently available on the market.

The break-out board includes mounting pads for a small lithium battery allowing for quick re-acquisition (1 second) on power up. Typical data retention times are several days depending on the lithium battery. Lithium battery not included.
