ESP8266 Module

ESP8266 WROOM Wi-Fi Module

ESP-WROOM-02 is a low-power 32-bit MCU Wi-Fi module, based on the ESP8266 chip. TCP/IP network stacks, 10-bit ADC, and HSPI/UART/PWM/I2C/I2S interfaces are all embedded in this module.

ESP-WROOM-S2 uses a 2 MB SPI flash connected to HSPI, working as the SDIO/SPI slave with the SPI speed of up to 8 Mbps.



Fully Certified

Wi-Fi Alliance, SRRC, FCC, CE ( RED ), TELEC, IC & KCC Certified

RoHS, Halogen Free, REACH & CFSI Compliant


Output Power: +22dBm peak power in FCC certification

Small Form Factor

ESP8266 Module can be easily integrated into space-limited devices, due to its small size of only 18mm x 20mm (ESP-WROOM-02) / 16 mm x 23 mm (ESP-WROOM-S2). 

Other Features

ESP8266 Module can operate in low-power connectivity mode; for instance, if it operates in DTIM10, it only consumes 1.2mW while maintaining a Wi-Fi connection. The module also integrates an SPI flash of 16 Mbits used for storing user programs, data and firmware.
