1 介绍
- Mini Shield for NanoPi Duo是一个专为NanoPi Duo定做的功能扩展底板,扩展了网口、调试串口、音频、USB等常用接口。
- 板上搭载了JM20329 USB转SATA芯片,提供了mSATA接口,方便外接半高mSATA接口的SSD。
- 板上还使用了FE1.1s扩展了4个USB Host接口,可外接常用USB设备。
- 扩展的调试串口和网络接口,能方便的连接串口模块和有限网络。
- 板上的咪头和3.5mm音频输出接口,能方便的录制和播放音频。
- 板子左上角的2x9 Pin排针引出了NanoPi Duo的IO接口,方便连接其他功能模块。
- 板子背面的6Pin SPI接口,能方便外接SPI设备。
- 底板和树莓派的尺寸和螺丝孔位置相同,可装配在树莓派的外壳中。
