在espressif的英文官网上，esp8266被称为esp8266ex，那么esp8266ex是什么意思呢？
https://www.espressif.com/en/products/hardware/esp8266ex/resources
原来，我们平常所说的esp8266，用英文的准确说法是esp8266系列的其中一个型号esp8266ex，只不过习惯了不叫ex而已。另外esp8266还有一个型号叫esp8285，不过esp8285很少时候需要用到，只是flash的大小增加了

先不说物联网的服务端，如果只研究硬件ESP8266和ESP32，
可以参考的资料其实很少，比较友好的只有安信可和零知实验室。
所以剩下能参考的只有那些闭源服务平台，例如blynk和blinker。
我发现机智云（gokit）也提供不错的代码资料，支持arduino uno和stm32。
实际上可以整理简化一下，只剩下点灯外设，甚至可能那些ESP8266的API
调用固件是不开源的。只是目前似乎还没有较好的物联网相关的收集，
真的要深入研究的话还是比较吃力，我打算以后学前端技术时会顺便做这方面的整理
