Details
Hits: 57793

This GNSS/GPS receiver module kit is mostly SMD (pre-assembled), and includes a high sensitivity active antenna with 2m coax and SMA connectors. It has three onboard LEDs for visual status indication, 3.3V regulator and power supply filtering, and 5V logic level conversion. It's easy to build and directly compatible with all QRP Labs kits.

Update April 2022: The QLG2-SE was a temporary replacement for QLG2 during the global semiconductor shortage. However we managed to get new supplies of the microcontroller, so the QLG2 is now back!

The highly popular QLG1 GPS module had to be retired in February 2021 due to supply problems, and was replaced by the QLG2, backwardly compatible with QLqlg1G1 but including multi-satellite constellation support, active patch antenna on 2m coax, and many additional functions. As of June 2021, due to the global semiconductor shortage it is no longer possible to source the required components to produce QLG2. Therefore until the semiconductor situation improves, will will produce QLG2-SE. It retains the same E108 GPS module (multi satellite system support) and active patch and 2m coax. However the additional functions provided by the microcontroller are absent, since the microcontroller itself, is absent. 

QLG2-SE stands for: QRP Labs GNSS module Mk2, Special Edition

Features:

  • Supply voltage range 3.3 to 6V.
  • Board 80 x 37mm (Same as Ultimate3S, VFO and Clock kits).
  • Optionally may be snapped into smaller size 2.1 x 1.46" (53.3 x 37mm)
  • Multi GNSS satellite constellation receiver supports the following systems GPS (US), Galileo (Europe), GLONASS (Russia) and Beidou (Chinese) - giving a faster more accurate position fix. GPS and Beidou are enabled by default (others need configuration). 
  • Supplied with included active antenna, approx 2m coax and SMA connectors.
  • 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.
  • SMD assembly already undertaken by factory facility - only SMA connector, and optional pin headers to solder.
  • Space provided for optional ultra-capacitor for faster hot-start
  • All modules will be fully tested before shipment.
