WROOM-02 WIFI Module, ESP8266, 4MB [D/U]

Description

Features

• 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 SPI flash connected to HSPI, working as the SDIO/SPI slave with the SPI speed of up to 8 Mbps.
• 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).
• Reliable and most certificate:
  • Wi-Fi Alliance, SRRC, FCC, CE, TELEC, IC & KCC Certified
  • RoHS, Halogen Free, REACH & CFSI Compliant
  • HTOL, ESD-HM, MSL, μHAST, HTSL
  • Output Power: +22dBm peak power in FCC certification
• 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.
• Module is directly supplied from Espressif, sufficient stock and constant price.

Current offer SPI Flash Size = 4MB for all variations

Variation:

• WROOM-02D/U further optimized RF performace, pin-to-pin compatible with WROOM-02
• WROOM-02D – on board PCB antenna
• WROOM-02U – on board IPEX antenna connector, can mount external atenna.
