Arduino uno板子

需先下载程序后接线，否则会下载失败

GPS模块VCC Arduino的5v

GPS模块GND Arduino的GND

GPS模块TXD Arduino的RX（数字IO 0）

GPS模块RXD不接

GPS模块PPS不接



若使用Arduino leonardo板子

需要将代码中所有的Serial修改为Serial1-Arduino uno board

Need to download the program after the wiring, otherwise it will download failure

GPS module VCC　　　　Arduino 5v

GPS module GND　　　　Arduino s GND

GPS module TXD　　　　Arduino RX (digital IO 0)

GPS module RXD not connected

GPS module PPS does not connect



If you use Arduino leonardo board

You need to change all the code in Serial to Serial1
