ESP32-WROOM-32 Core Dev Board for ESP32 Development vs Waveshare ESP32-S3 1.47inch LCD Display Development Board

Overview of the Products

In this comparison, we will evaluate the ESP32-WROOM-32 Core Dev Board for ESP32 Development and the Waveshare ESP32-S3 1.47inch LCD Display Development Board. The former is priced at C$13.99, while the latter is significantly higher, at C$31.99. This price difference reflects the unique features and capabilities each board offers for IoT development and advanced applications.

Design and Build Quality

The ESP32-WROOM-32 Core Dev Board features a robust design focused on facilitating IoT projects. It is powered by the ESP32 microcontroller, which provides excellent processing capabilities for various applications. In contrast, the Waveshare ESP32-S3 1.47inch LCD Display Development Board includes a high-performance dual-core processor running at up to 240MHz, making it ideal for advanced human-machine interface (HMI) applications. This board also features a built-in 1.47-inch LCD display with a resolution of 172×320, adding a visual component that the ESP32-WROOM-32 lacks. Thus, while both boards are well-built, the inclusion of a display on the Waveshare board enhances its functionality.

Processing Power

When it comes to processing power, the Waveshare ESP32-S3 outshines the ESP32-WROOM-32. The Waveshare board utilises an Xtensa 32-bit LX7 dual-core processor, which operates at up to 240MHz, providing a significant advantage in handling more complex tasks. The ESP32-WROOM-32, while equipped with the capable ESP32 microcontroller unit, does not specify its clock rate but is known to offer robust performance for standard IoT applications. Thus, for projects requiring higher processing power and speed, the Waveshare board is the clear choice.

Connectivity Options

Both the ESP32-WROOM-32 and the Waveshare ESP32-S3 development boards offer impressive connectivity options, but with slight differences. The ESP32-WROOM-32 supports Wi-Fi and Bluetooth, catering well to IoT applications that require wireless communication. On the other hand, the Waveshare board also supports 2.4GHz Wi-Fi and Bluetooth 5 (LE) with an onboard antenna, ensuring reliable wireless connectivity. The additional benefits of Bluetooth 5 on the Waveshare board can enhance device communication range and speed, making it a more future-proof option for developers pursuing advanced connectivity.

Memory and Storage

In terms of memory and storage, the Waveshare ESP32-S3 again takes the lead. It boasts a configuration of 512KB SRAM, 384KB ROM, 16MB Flash, and 8MB PSRAM, which collectively provide ample storage for efficient operation and program execution. In contrast, the ESP32-WROOM-32 does not specify its memory capacity, which may be a limiting factor for more complex applications requiring extensive data handling. Therefore, for developers whose projects demand substantial memory resources, the Waveshare board is more suited to meet those needs.

Features and Usability

The ESP32-WROOM-32 Core Dev Board is designed with simplicity in mind, making it a great option for those new to IoT development. It supports popular development environments like Arduino IDE, streamlining the coding process. Meanwhile, the Waveshare ESP32-S3 incorporates multiple I/O interfaces, a TF card slot for external storage, and a battery charging module, enhancing its versatility for various applications. The added 6-axis IMU on the Waveshare board can facilitate motion sensing and gesture detection, making it an excellent choice for projects that require interactive functionalities.

Target Users and Applications

The target users for the ESP32-WROOM-32 are typically hobbyists and beginners in IoT development who seek an affordable entry point. It provides all the necessary features to develop basic IoT applications without overwhelming users with complexity. Conversely, the Waveshare ESP32-S3 is tailored towards advanced developers and professionals who require a more powerful platform for creating sophisticated applications with user interfaces. The additional features and higher processing power make it suitable for projects such as interactive displays or advanced sensor networks.

Price Comparison

The price difference between the two boards is considerable, with the ESP32-WROOM-32 priced at just C$13.99, while the Waveshare ESP32-S3 is priced at C$31.99. This C$18 price gap reflects the additional features and capabilities offered by the Waveshare board, including its display, enhanced processing power, and greater memory capacity. For budget-conscious developers, the ESP32-WROOM-32 presents a compelling option, while those with a higher budget may find that the additional investment in the Waveshare board provides significant long-term benefits.

Which should you buy?

Ultimately, the choice between the ESP32-WROOM-32 Core Dev Board and the Waveshare ESP32-S3 1.47inch LCD Display Development Board hinges on your specific project requirements and budget constraints. If you are a beginner or working on basic IoT projects, the ESP32-WROOM-32 is an affordable and effective option. However, for advanced projects requiring higher processing capabilities, additional memory, and user interface features, the Waveshare ESP32-S3 justifies its higher price with superior functionality. Consider your needs carefully to select the board that best aligns with your development goals.
