基于MTK方案AG3335芯片设计的款超小型超低功耗定位器

价格：50000元

客户：追影定位器

鸽子定位器 MTK 低功耗 AG3335

案例背景：

当时设计了一款鸽子定位器，用于记录鸽子比赛的飞行轨迹，由于是安装到鸽子腿上，要求定位器体积小质量轻功耗低。我们采用mtk最新芯片完成了产品的开发，完全符合预期。

通过研究对比选定MTK的AG3335芯片，该芯片系统开放openMCU，可在GPS芯片上自由编程实现系统需要功能。在功耗表现上也是同领域佼佼者。

功耗对比图：

GPS定位技术MTK全球领先的企业，其中MT3333芯片已发布8年时间，在市场上得到广泛应用，也是性能相当出色的经典产品。MTK的卫星定位技术积累是相当雄厚的。

产品采用MTK最新的基于Cortex-M4架构12nm技术的定位芯片AG3335MN，该芯片是在MT3333的基础上发展而来，主频530MHz、配备4MB flash、664KB SYSRAM、80KB UserSRAM、除了GPS双频接收解析功能外还包含一些基础外设：2.0USB、4路10bitADC、串口、I2C、SPI、3路PWM，这些资源完全满足系统所有功能，可以实现单芯片解决方案。

芯片定位性能如下图所示：

定位系统框架图：

系统的电源单元，输入直流5V，充电芯片转换至电池电压给电池充电，电池电压直接作为系统主电源供电，辅助电源将电压通过DCDC进一步降低，以供给CPU核心处理单元，这样有利于提高电池电量利用率，降低功耗，最终整机在定位期间12mA、待机时21uA。GPS天线信号采用一级放大和一级滤波送入芯片。定位器和充电器之间通过串口通信，进行数据交互设置和数据上报。充电器采用4G的Cat1模块通信，传输速度快，覆盖面大，技术不易被淘汰。
