- ESP8266 is a 32-bit low power micro-controller (MCU) Wi-Fi Module that integrates TCP/IP network stacks, and includes 10-bit ADC with HSPI, SDIO, UART, PWM, I2C, and I2S interfaces.
- The module is highly integrated. It consumes extremely low power while providing wireless internet connection for embedded devices.
- It can be easily integrated into resource-limited devices due to its small form factor of only 18mm x 20mm.
- In addition to the ESP8266EX chipset, the module also integrates an SPI flash with 32Mbits capacity, along with a SOP8-150mil package. The SPI flash is incredibly useful for storing user programs and firmware.
