Intended Uses
The GPS Expander V4 (the GPS) is intended for recreational use exclusively in model planes, boats and cars. Other uses are not

Features
The GPS is designed to be used with all present Eagle Tree recording, OSD, PowerPanel LCD, and wireless telemetry products. The GPS updates at
10Hz, consumes very little power, and has battery backup for quick hot and warm starts.
Our Data Recorder software includes support for Google Earth, including live mode display, and Google Earth Track support for logged data.
The GPS includes onboard filtering, as well as a toroid ring filter, to improve signal reception, especially when used in conjunction with First Person
View video transmitters.
The GPS’s built-in LED indicates when a 3D fix has been attained, for convenient usage. The LED flashes UNTIL a 3D fix is attained, then stops
flashing.
The GPS is tiny and lightweight, making it perfect where weight and size are issues. See the Specifications section below for more information.
With our Windows software, and now with Google Earth™ software, your GPS data can be easily and fully visualized.

Connecting the GPS to the eLogger V3/V4
The 4 wire connector attached to the GPS plugs into the eLogger V3/V4 as shown in Figure 2. Make

Note: The GPS draws significant current from the eLogger. When the eLogger is powered by a
higher voltage pack, such as an 8s or larger pack, or a pack above 30 volts, the eLogger’s
regulator may shut off after a short period when used with the GPS. If you find this is happening,
please use our “Battery Backup Harness”, part number CAB-BAT-BACK for the eLogger V3, or use
