1 介绍
- NanoHat-Hub是一个专为NanoPi NEO量身设计的接口扩展模块。NanoHat-Hub通过I2C接口和NEO通讯，作为从设备的单片机MEGA328扮演NEO和传感器模块之间翻译官的角色，HUB提供了三个I2C接口、三个模拟接口，两个串口（一个NEO串口，一个单片机串口）和四个数字接口。传感器模块通过4Pin的连接线直接接在NanoHat-hub上。
- 连接NanoPi NEO和传感器的扩展板，NanoHat扩展板直接插在NanoPi NEO上面，通过I2C接口、串口、数字/模拟接口建立传感器与NEO之间的数据传输。所有的模块可以通过4个引脚的连接线直接连接到NanoHat扩展板接口上。
- NanoHat扩展板带有三路I2C接口，三路模拟接口，四路数字接口，两路串口。
