ESP-WROOM-02 module is based on ESP8266EX chip design and development of the IoT wireless module.
It integrates TCP/IP network protocol stack, 32-bit MCU with low consumption, 10 bit ADC with HSPI precision,UART, PWM, 12 c and 12 s interface, etc.
ESP-WROOM-02 can work under low power link mode, such as DTM10 mode, and only 10 mw,
maintain the WiFi connection of the module is configured with 16 MBTS SPI flash memory,
can be used to store the user program and firmware.
