ESP-WROOM-02D

[IC]:ESP8266

[Frequency]:2.4GHz

[Distance]:300m

[Interface]:UART/HSPI/I2C/I2S/IR Remote Control

[Introduction]:ESP-WROOM-02D and ESP-WROOM-02U are ESP8266EX-based modules developed by Espressif. Compared to ESP-WROOM-02, the RF performance of ESP-WROOM-02D and ESP-WROOM-02U are optimized. Besides, ESP-WROOM-02U integrates a U.FL connector. Please see Chapter 8 for details of U.FL connector.
