Introduction

AI Translation

ESP-WROOM-02D and ESP-WROOM-02U are SMT modules integrating ESP8266EX, with optimized RF performance over ESP-WROOM-02. ESP-WROOM-02U integrates a U.FL connector and requires an IPEX antenna.

ESP8266EX features an ultra-low-power Tensilica L106 32-bit RISC processor with CPU clock speed up to 160MHz, supporting RTOS and Wi-Fi protocol stack, leaving up to 80% of processing capacity available for application programming and development.

ESP8266EX integrates an on-chip memory controller and memory units including ROM and SRAM. The MCU can access memory units via iBus, dBus, and AHB interfaces. ESP8266EX supports external Flash via SPI interface, with a theoretical maximum of 16MB SPI Flash. ESP-WROOM-02D and ESP-WROOM-02U are configured with 2MB SPI Flash, supporting the following SPI modes: Standard SPI, DIO (Dual I/O), DOUT (Dual Output), QIO (Quad I/O), and QOUT (Quad Output).

ESP-WROOM-02D and ESP-WROOM-02U use a 26MHz crystal oscillator with required crystal accuracy of ±10PPM.
