ESP-WROOM-02 Wifi Module

ESP-WROOM-02 is a WiFi Module that integrates TCP/IP network stacks, 32-bit low power micro-controller (MCU), and 10-bit ADC with HSPI, SDIO, UART, PWM, I2C, and I2S interfaces. The module features high integration level and low power consumption, and can provides wireless internet connection for a wide range of embedded devices. It can be easily integrated into resource-limited devices due to its small footprint of only 18mm x 20mm.

Apart from using the ESP8266EX chipset, this module also integrates an SPI flash with 16Mbyte capacity, and SOP8-150mil package. The flash can be used to store user programs and firmware.

• IEEE 802.11b/g/n at 2.4 GHz
• Integrated low power 32-bit MCU
• Integrated 10-bit ADC
• Integrated TCP/IP protocol stack
• Integrated TR switch, balun, LNA, power amplifier and matching network
• Integrated PLL, regulators, and power management units
• Various interfaces available, including SDIO, HSPI, UART, I2C, I2S, IR, PWM, GPIO, etc.
• Supports antenna diversity
• Deep sleep power <10uA, Power down leakage current < 5uA
• Wake up and transmit packets in < 2ms
• Standby power consumption of < 1.0mW (DTIM3)
• +20dBm output power in 802.11b mode
• Operating temperature range -40C ~ 125C

• 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.
