Support Raspberry Pi model A, B, A+, B+, Zero, 2, 3 with its' L80-39 GPS chip inside.
Communicates satellite with UART or USB.
CP2102 as USB to UART Bridge chip, stable and faster.
The L80-39 with 66 search channels and 22 simultaneous tracking channels,it acquires and tracks satellites in the shortest time at Outdoor.
Attention This module is fit for outdoor operation. please put the Antana in the open air.
Features
-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
Built-in LNA for better sensitivity
RTC battery-compatible
1x8 male headers, USB micro Interface
includes CP2102 Module Serial Converter USB 2.0 To TTL UART
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 |
VCC | Red wire |
GND | Black wire |
TXD | Green wire |
RXD | White wire |
Part List:
1 x USB-Port-GPS(L80-39) module
1 x USB data wire
Documents:
USB-Port-GPS Module SKU:EZ-0048
Dimensions | 120mm x 80mm x 23mm |
Weight | G.W 26g |
Battery | Exclude |
支持樹莓派模型A,B,A +,B +,零,2,3,其“L80-39 GPS芯片內部。
通信與UART或USB衛星。
CP2102如USB轉UART橋接芯片,穩定,速度更快。
66搜索頻道和22個同步跟踪頻道的L80-39,它獲取並跟踪在室外最短的時間內衛星。
警告 該模塊是適合戶外作業。請把Antana在露天。
特徵
-165 dBm的靈敏度,1Hz的(默認值),最高5Hz的,66通道
至少,100mA的電流抽獎啟動。
PPS輸出可用於帶衛星協調時間。
內置貼片天線在室外SMA連接器,外置天線用於室內使用時,當它工作得很好
修復狀態指示燈閃爍,讓你知道當GPS確定的當前坐標
EASY™,先進的AGPS技術,無需外部存儲器
這可以通過PPS同步NMEA功能可以實現支持時間服務應用程序
內置LNA為更好的靈敏度
RTC電池兼容
1×8男頭,USB接口微型
包括CP2102模塊串口轉換器USB 2.0 TTL UART
如何連接起來
UART風格:
由於樹莓派3,B型的串行口的問題,它可能會導致意想不到的問題,我們建議您不要與樹莓派直接與GPIO引腳連接GPS模塊。
1.You需要一個USB轉TTL線連接GPS模塊和樹莓派,你可以線它像這張圖:
GPS模塊 | 導線顏色 |
VCC | 紅線 |
GND | 黑線 |
TXD | 綠線 |
RXD | 白線 |
