ESP32 WROOM MCU Module - 8MB (Dual Antenna)

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.

  • 2.4 GHz WiFi + Bluetooth ® + Bluetooth LE module
    • 802.11b/g/n WiFi
    • Bluetooth V4.2 BR/EDR and Bluetooth LE specification
  • Xtensa® dualcore 32bit LX6 microprocessor
  • 8MB flash
  • 40 MHz crystal oscillator
  • 24 GPIOs
  • On-Board dual PCB Trace Antennas
  • 3.0 ~ 3.6 VDC Operating Voltage
  • Pin Compatible with the ESP32-WROOM-32E

ESP32 WROOM MCU Module - 8MB (Dual Antenna) Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

3 Soldering

Skill Level: Competent - You will encounter surface mount components and basic SMD soldering techniques are required.
See all skill levels

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.
