The ESP32 WROOM MCU Module - 8MB (Dual Antenna) is a module that achieves high-quality, wireless connectivity across large areas, using two complementary PCB antennas in different directions. Also, based on its industry-leading technical specifications, the co-existence of WiFi and Bluetooth (Classic & Low-Energy) connectivity, and its low-power consumption modes, the users of ESP32-WROOM-DA will be able to bring to life a wide range of complex IoT application scenarios.

The module features the ESP32-D0WD-V3 chip based on 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. While being used, the module works according to signal strength, selecting the strongest signal to ensure continuous communication. When a weak signal is detected, the module continues to work with an API call that helps it switch to the other antenna with a stronger signal.
