Introduction; Getting To Know Your Qlg2-Se - QRP Labs QLG2-SE Manual

1. Introduction

The QLG2-SE GNSS (Global Navigation Satellite System) receiver module is an upgrade
over the former QLG1 with higher performance and highly flexible features:
QLG2-SE is a reduced functionality version of the QLG2. Compared to QLG2, it lacks the
USB to Serial converter interface and the capability to use an optional LCD module.
Multi GNSS satellite constellation receiver supports GPS (US), Galileo (Europe),
•
GLONASS (Russia) and Beidou (Chinese) - (default GPS + Beidou) - giving a faster
more accurate position fix – Module is E108-GN01 (GK9501 GNSS chip set)
Supplied with included magnetic-mount active antenna, approx 2m coax and SMA
•
connectors
Supply voltage range 3.3 to 6V.
•
Board 80 x 37mm (Same as, and compatible with, Ultimate3S, VFO and Clock kits).
•
Onboard LEDs for status indication: Red (Power), Yellow (Serial data) and Green
•
(PPS).
2.8 to 5V logic level conversion to provide 5V serial data for full compatibility with all
•
QRP Labs kits.
Supports 2.8/3.3V logic OR 5V logic (jumper wire selected)
•
SMD assembly already undertaken by factory facility - only SMA connector to solder.
•
Space provided for optional ultra-capacitor for faster hot-start
•
All QLG2-SE GPS modules are comprehensively tested before shipment including:
Active antenna with 2m coax and SMA connector functions correctly
•
Satellite reception and Time To First Fix is under 1 minute
•
Serial data and 1pps outputs are correctly present
•
PLEASE READ THE BASIC ASSEMBLY AND USE
