ESP32-WROOM-DA Module Specification

At the core of the ESP32-WROOM-DA module lies the ESP32-D0WD-V3 chip.  

A technological marvel boasting the chip comes with the following specification:

  • Xtensa® 32-bit LX6 dual-core processor.
  • The maximum frequency of 240 MHz
  • SRAM of 520 KB 
  • ROM of 448 KB
  • 16 KB SRAM in RTC

The ESP32-D0WD-V3 chip represents an evolution from the ESP32-D0WD chip, now referred to as ECO V3. Espressif’s recent implementation of a wafer-level change enhances performance and functionality across the ESP32 Series, particularly evident in the ECO V3 chip.

You can find all significant design changes in the ECO V3 chip.

Espressif has stated that this new module works according to signal strength, selecting the strongest signal to ensure continuous communication. In scenarios where a weak signal is detected, the module seamlessly switches to the alternative antenna with superior signal strength, facilitated by a specialized API call.

ESP32-WROOM-32E DA Pinout

The ESP32-WROOM-DA stands as a pin-compatible successor to the ESP32-WROOM-32E module. This compatibility streamlines the transition for users familiar with the previous iteration, including those utilizing the widely adopted ESP32-WROOM-32D.

The ESP32-WROOM-DA module uses GPIO 2 and GPIO 25 to select which antenna is active. These are referenced from the datasheet for the module in table 3 (just after the pin assignment list). Make sure you are selecting “ESP32-WROOM-DA Module” in the boards menu which has additional defines added to enable dual antenna mode support.
