The ESP8266 is a low-cost Wi-Fi microcontroller, with built-in TCP/IP networking software, and microcontroller capability, produced by Espressif Systems [1] in Shanghai, China. The chip was popularized in the English-speaking maker community in August 2014 via the ESP-01 module, made by a third-party manufacturer Ai-Thinker.

ESP8266 NodeMCU Hardware Overview. When it comes to ESP8266 development boards, the NodeMCU is by far the most widely used option. This is what we will use for our experiments. Don’t worry if you have a different board; the information on this page should still be useful. Let’s take a deep dive into the hardware overview of the ESP8266 NodeMCU.

Upgrade from ESP8266 to ESP32-C2 for enhanced performance. ESP8266 is a highly integrated Wi-Fi 4 SoC ideal for IoT projects.

The ESP8266 is an affordable development board that combines control of outputs/inputs and Wi-Fi capabilities. It is one of the cheapest solutions on the market for DIY IOT and Home Automation projects. It supports the following peripherals: I/O, SPI, I2C, I2S, SPI, UART and ADC. Additionally, the ESP8266 NodeMCU can be programmed using the ...

Aug 5, 2024 · Low-power: the ESP8266 consumes very little power when compared with other microcontrollers and can even go into deep sleep mode to consume less power; Wi-Fi: the ESP8266 can generate its own Wi-Fi network (access point) or connect to other Wi-Fi networks (station) to get access to the internet. This means the ESP8266 can access online services ...
