The ESP32-WROOM-DA, which 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.
The module is pin compatible with the ESP32-WROOM-32E.
Features:
- 2.4 GHz WiFi + Bluetooth ® + Bluetooth LE module

Jargon buster
Plain-language definitions for the technical terms used above.
- API
- An API is a software interface that lets a program control hardware or features provided by the operating system. In this product, API support matters if you want your software to adjust display settings such as brightness or contrast automatically.
- ESP32
- ESP32 is a family of microcontroller modules with built-in wireless features such as Bluetooth and WiFi. Knowing this product uses an ESP32-based module helps explain how it provides wireless serial communication and firmware update features.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- SRAM
- Fast temporary memory used by a processor while a program is running. More SRAM helps with projects that handle larger data buffers, networking, displays, or more complex code.
