Espressif ESP32-WROOM-DA with Dual Antennas for Improved Wireless Connectivity

Espressif Systems is launching a new wireless module ESP32-WROOM-DA, with two antennas oriented in different directions. It achieves high-quality, wireless connectivity across large areas.

Better wireless connectivity directly means operating at lower power consumption will be possible, improving the battery backup time.

In many industrial environments, external antennas are preferred for the same reason but they make the solution size bigger and adds some challenge to the enclosure design. It will be a good advantage to have two antennas on the module itself.

The ESP32-WROOM-DA module will be based on an ESP32-D0WD-V3 chip, having an Xtensa® 32-bit LX6 dual-core processor with a maximum frequency of 240 MHz, along with 520 KB of SRAM and 448 KB of ROM.

The module works according to signal strength, selecting the strongest signal to ensure continuous communication.

When a weak signal is detected, the module will work with an API call that helps it switch to the other antenna with a stronger signal.

ESP32-WROOM-DA is pin-to-pin compatible with ESP32-WROOM-32E, thus facilitating quick and easy migration between these two modules. The only change is, now you need to have a little more space inside the enclosure to accommodate a bigger module size.

As per Espressif “The unique antenna design of ESP32-WROOM-DA has resulted in the module’s excellent wireless communication, even under difficult circumstances. Thus, makers using ESP32-WROOM-DA can now develop IoT applications that need stable connectivity over a broad spectrum, or deploy Wi-Fi in challenging and hazardous environments or overcome communication problems in Wi-Fi-dead spots.”

This module will be available soon on leading distributors portals. For now, If you want to learn more about the ESP32-WROOM-DA module, please contact Espressif’s customer support team.
