Taking a break

 We're taking a break moving shop and hope to be back soon. We hope to start shipping orders in Nov 2018. 

USB Port GPS Module L80-39 For Raspberry Pi model A, B, A+, B+, Zero, 2, 3. Communicates with satellite module via UART or USB. It uses the CP2102 as USB to UART Bridge chip, stable and faster. The L80-39 uses 66 search channels and 22 simultaneous tracking channels acquiring and tracking satellites in the shortest time when Outdoors.

Attention: This module is fit for outdoor operation. please put the Antenna in the open air.


  • -165 dBm sensitivity, 1Hz (Default), up to 5Hz, 66 channels
  • At least 100mA current draw to startup.
  • PPS output can be used to coordinate time with satellite.
  • Internal patch antenna which works quite well when used outdoors SMA connector for external active antenna for when used indoors
  • Fix status LED blinks to let you know when the GPS has determined the current coordinates
  • EASY, advanced AGPS technology without external memory
  • Support time service application which can be achieved by PPS sync NMEA feature

How to wire it up

Uart Style:

Because of the Serial port issue of Raspberry Pi 3, Model B, it may cause unexpected problem, we suggest that you do not connect GPS module with Raspberry Pi directly with GPIO Pins.

1.You need a USB-to-TTL cable to connect GPS module and Raspberry Pi ,and you can wire it up like this chart:

GPS module    Wire color    
VCCRed wire
GNDBlack wire
TXDGreen wire
RXDWhite wire
