The ESP8266 ESP-01 is a Wi-Fi module that allows microcontrollers access to a Wi-Fi network. This module is a self-contained SOC (System On a Chip) that doesn’t necessarily need a microcontroller to manipulate inputs and outputs as you would normally do with an Arduino, for example, because the ESP-01 acts as a small computer. Depending on the version of the ESP8266, it is possible to have up to 9 GPIOs (General Purpose Input Output). Thus, we can give a microcontroller internet access like the Wi-Fi shield does to the Arduino, or we can simply program the ESP8266 to not only have access to a Wi-Fi network, but to act as a microcontroller as well. This makes the ESP8266 very versatile, and it can save you some money and space in your projects.

ESP8266 Pin Configuration

Pin Number Pin Name Alternate Name Normally used for Alternate purpose
1 Ground Connected to the ground of the circuit
2 TX GPIO – 1 Connected to Rx pin of programmer/uC  to upload program Can act as a General purpose Input/output pin when not used as TX
3 GPIO-2 General purpose Input/output pin
4 CH_EN Chip Enable – Active high
5 GPIO – 0 Flash General purpose Input/output pin Takes module into serial programming when held low during start up
6 Reset Resets the module
7 RX GPIO – 3 General purpose Input/output pin Can act as a General purpose Input/output pin when not used as RX
8 Vcc Connect to +3.3V only
