ESP32-WROOM-DA (the DA is for Dual Antenna) is a powerful Wi-Fi + Bluetooth Classic + Bluetooth LE MCU module, with two complementary PCB antennas in different directions. Packed with 8 MB of internal QSPI Flash, it has lots of memory and great WiFi connectivity no matter where or how it is installed.
ESP32-WROOM-DA is pin-to-pin compatible with ESP32-WROOM-32E, thus facilitating quick and easy migration between these two modules. 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.
Program it just like any other ESP32 module, it will automagically use the best antenna for signal strength.
At the core of the module is the ESP32-D0WD-V3 chip. The chip embedded is designed to be scalable and adaptive. There are two CPU cores that can be individually controlled, and the CPU clock frequency is adjustable from 80 MHz to 240 MHz. The chip also has a low-power coprocessor that can be used instead of the CPU to save power while performing tasks that do not require much computing power, such as monitoring of peripherals.ESP32-D0WD-V3 integrates a rich set of peripherals, ranging from capacitive touch sensors, Hall sensor, SD card interface, Ethernet, high-speed SPI, UART, I2S, and I2C.
For advanced users only! This product is just the module — which can be difficult to use. You’ll need to solder it onto a board with supporting circuitry. This module is for developers at this time.
