ESP - 01 is wireless wifi launcher, what is the internal structure of it? ESP8266 is a developed by Shanghai LeXin information technology [1] can be a very low cost and micro controller using a complete TCP/IP protocol stack of wi-fi IoT control chip,

ESP8266

Produced by Ai - Thinker ESP - 01 module

Producers LeXin 32-bit microcontroller CPU information technology type @ 80 MHz (default) or 160 MHz memory 32 KiB instruction set, 80 KiB user data input 16 needle GPIO next generation product ESP32

Produced by Ai - the Thinker of ESP in August 2014-01 chip first attracted the attention of the western "geeks, this small module allows the micro-controller by hayes command set using TCP/IP protocol stack is connected to a wi-fi network, however, in the original chips used almost no English documents and accept orders, [2] because of very little module on external components, led to its price is very cheap, and attracted many a guest to study and use of the module, the development of supporting software used in the chip as well as guidance on the use of the Chinese language in multilingual translation, [3]

ESP8285 ESP8266, 1 mib is built into the flash memory, which allows single chip device can be directly connected to wi-fi, [4]

The subsequent product is ESP32 issued in 2016,
