The ESP8266 is a low-cost Wi-Fi microchip with full TCP/IP
stack and microcontroller capability produced by Shanghai-based Chinese
manufacturer, Espressif Systems.
The chip first came to the attention of western makers in
August 2014 with the ESP-01 module, made by a third-party manufacturer,
Ai-Thinker. This small module allows microcontrollers to connect to a Wi-Fi
network and make simple TCP/IP connections using Hayes-style commands. However,
at the time there was almost no English-language documentation on the chip and
the commands it accepted. The very low price and the fact that there were very
few external components on the module which suggested that it could eventually
be very inexpensive in volume, attracted many hackers to explore the module,
chip, and the software on it, as well as to translate the Chinese
documentation.
The ESP8285 is an ESP8266 with 1 MiB of built-in flash,
allowing for single-chip devices capable of connecting to Wi-Fi.
The successor to these microcontroller chips is the ESP32.
