红旭无线开发板

红旭无线开发板主要由Nordic 52840模块组成,涵盖了目前市面上大部分的主流无线通讯协议,可以满足大部分的物联网应用场景。

简介

红旭无线开发板主要由以下两大部分组成

  • NRF52840核心板
  • NRF52840的各个外设配件(例如传各种感器模块、语音识别模块、锂电池充放电模块等等)

红旭无线开发板包括丰富的硬件资源,NRF52840模块的IO口均全部引出。同时,红旭无线开发板支持BLE5.0Zigbee3.0Thread2.4G以及SIG MESH等市面上主流的无线通讯协议,基本上满足用户大部分的功能需求,特别是智能家居的应用场景。

红旭无线开发板可以同时运行BLE5.0+Zigbee/Thread或者SIG MESH两种模式,并且提供丰富的示例以及软件实战教程,希望大家通过红旭无线开发板学习到这些无线技术,从而在工作上如鱼得水,获得更高的薪酬,为共和国的无线事业作出贡献,登上人生巅峰。 NRF52840+ESP32 Mini海报图

以上仅显示Nordic 52840相关的内容,想了解ESP32相关的内容,请在另外一个代码仓查看

注意,由于人员配备不足以及ESP32的资料足够多,目前已经放弃对ESP32的技术支持,纯限群里自主交流(群里有相应的ESP32大佬)

技术交流

  • QQ群

    QQ群主要用于自主的技术以及行业信息交流,无广告纯技术探讨 (仅限技术开发者加入,非技术人员请勿加入免得发现被踢)
