全球极小尺寸，极轻GLONASS+GPS 双模GPS，仅5.3g。
BN-220 GPS一体模块尺寸22mm*20mm*6mm：
购买BN-220 GPS，赠送连接线2根，双面胶1个。
模块的引脚分别是：
1.GND,接地。
2.TX,模块的数据输出。
3.RX,模块的数据输入。
4.VCC，3.0V--5.5V。
指示灯：
1. TX 灯，蓝灯，上电蓝灯闪烁，表示有数据输出。
2.PPS灯，红灯，未定位该灯不亮；3D定位后，开始闪烁。
说明：该模块可以设置成GPS+GLONASS双模，也可以设置成GPS+北斗双模。一般国外用GPS+GLONASS双模，国内用GPS+北斗双模。出货前提前说明，没有说明则按照默认GPS+GLONASS双模出货。
