DESCRIPTION

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 SDIO/SPI slave, with the SPI speed being up to 8 Mbps.

FEATURES

Fully Certified
  • Certified by Wi-Fi Alliance, SRRC, FCC, CE ( RED ), TELEC, IC & KCC
  • Compliant with RoHS, Halogen Free, REACH & CFSI
  • HTOL, ESD-HM, MSL, μHAST, HTSL
  • Output Power: +22dBm peak power in the FCC certification

Small-Form Factor
The ESP8266 Module can be easily integrated into space-constrained 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 a low-power connectivity mode. For instance, if it operates in DTIM10, it consumes only 1.2mW while maintaining a Wi-Fi connection. The module also integrates an SPI flash of 2MB used for storing user programs, data and firmware.
