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。
