Wi-Fi Module ESP8266-WROOM-02

The ESP-WROOM-02 module is a highly integrated WiFi 802.11 b/g/n module that consumes extremely low power while providing a wireless internet connection for embedded devices. With a very small form factor (18mm by 20mm), this wireless module easily assimilates into resource limited devices. These features make it a great choice for OEMs to connect their IoT (Internet of Things) applications.

Embedded with the ESP8266EX chip, the ESP-WROOM-02 module is a 32-bit low power micro-controller (MCU) that integrates with TCP/IP network stacks; the included 10-bit ACD interfaces with HSPI, SDIO, UART, PWM, I2C and I2S. Programs and firmware can be stored in the integrated SPI flash with 4MB capacity.
