ESP32-WROOM-DA Wi-Fi/BLUETOOTH® MCU Modules Espressif Systems ESP32-WROOM-DA Wi-Fi/BLUETOOTH® MCU Modules that come with two complementary PCB antennas in different directions. These modules have the same layout of pins as ESP32-WROOM-32E, except some pins are not led out, facilitating quick and easy migration between these two modules. With two unique antennas designed on one single module, ESP32-WROOM-DA can be used to develop IoT applications that need stable connectivity over a broad spectrum. It can also be used to deploy Wi-Fi in challenging and hazardous environments or overcome communication problems in Wi-Fi-dead spots. This module is ideal for indoor and outdoor devices for smart homes, industrial control, consumer electronics, etc.
