## 描述
-GPS 模块是一款内置了GPS小模组的M5Stack系列可堆叠模块。内置的GPS小模块名字为UBLOX NEO-M8N。堆叠了M5Core之后，你可以用UiFlow、Arduino和MicroPython来编程它。它都可提供全球定位信息，即使你在室外的任何地方。

+## 例程
+
+### 1. Arduino IDE
+
+```c++
+GPSRaw.begin(9600);
+
+if(GPSRaw.available()) {
+ int ch = GPSRaw.read();
+ Serial.write(ch);
+}
+```
+
+烧录[例程](https://github.com/m5stack/M5-ProductExampleCodes/tree/master/Modules/GPS/Arduino)之后，屏幕和串口显示终端会打印如下类似的信息
+
+```
+$GPGSA,A,1,,,,,,,,,,,,,25.5,25.5,25.5*02
+$BDGSA,A,1,,,,,,,,,,,,,25.5,25.5,25.5*13
