1.1 Module Overview
ESP32-WROOM-DA is a powerful Wi-Fi + Bluetooth + Bluetooth LE MCU module, with two complementary PCB
antennas in different directions. This module is embedded with ESP32-D0WD-V3 with a rich set of integrated
components including SPI flash and 40 MHz crystal oscillator. With two unique antennas design on one single
module, ESP32-WROOM-DA can be used to develop IoT applications that need stable connectivity over a broad
spectrum, or to deploy Wi-Fi in challenging and hazardous environments, or to overcome communication problems
in Wi-Fi-dead spots. This module is an ideal choice for indoor and outdoor devices for smart home, industrial
control, consumer electronics, etc.
