SIRF III 3模块GPS开发板/TTL/RS232接口电平/单片机

SIRF 3带TTL和232两种电平输出的GPS板再次升级，全新的GPS开发板带备份电池，使GPS开发板可以具备热启动、暖启动的功能，并且应买家建议，采用通用的2.54mm间距的排针引出，并且增加了秒脉冲输出及显示，可以通过板载LED来判断定位状态（绿色LED闪烁即定位成功） 另外，购买本板可免费获得本店的51单片机程序、串口软件、GPS电脑测试程序，及测试教程 本店另有制作USB转TTL小板，该板可用于STC的单片机烧录以及用来将GPS上的串行信号（TTL电平）转接到电脑USB口，测试及调试、学习都非常方便，GPS板详情请看实物照片：脚定义从左至右为VCC（5V）、TTL-TX、TTL-RX、232-TX、232-RX、PPS（秒脉冲）、GND $GPGGA,145856.000,2244.1009,N,11428.2919,E,1,06,1.2,52.0,M,0.0,M,,0000*50
