Waveshare ESP32-S3 1.47inch LCD Display Development Board vs IoTCrazy ESP32-WROOM-32U Dev Board with 3dBi Antenna

Overview of the Boards

When comparing the Waveshare ESP32-S3 1.47inch LCD Display Development Board and the IoTCrazy ESP32-WROOM-32U Dev Board with 3dBi Antenna, each board presents unique features tailored for different applications. The Waveshare board retails for C$31.99, while the IoTCrazy board is priced at a more budget-friendly C$18.99.

The Waveshare board is designed with advanced HMI applications in mind, featuring a built-in 1.47-inch LCD display, while the IoTCrazy board focuses on enhancing wireless connectivity with its detachable 3dBi antenna. Each board caters to distinct user needs, making them suitable for various development projects.

Performance and Processing Power

The Waveshare board boasts a high-performance dual-core processor running at up to 240MHz, which is optimal for demanding applications. In contrast, the IoTCrazy board utilises the ESP32-WROOM-32U, which has 520KB of SRAM, offering robust performance for multitasking and IoT projects.

While both boards leverage the power of dual-core processors, the Waveshare board’s higher clock speed may provide a slight edge in processing tasks requiring swift data handling. Users aiming for complex operations may find the Waveshare board more appealing, while those focused on simpler IoT applications can benefit from the reliable performance of the IoTCrazy board.

Connectivity and Range

Connectivity is a key feature for both development boards. The Waveshare ESP32-S3 supports 2.4GHz Wi-Fi and Bluetooth 5 (LE), ensuring reliable wireless connectivity for various applications. Meanwhile, the IoTCrazy board enhances its performance with a detachable 3dBi antenna, significantly improving the wireless range compared to standard onboard antennas.

For projects requiring long-range communication, the IoTCrazy board might be the better choice due to its external antenna, which is ideal for IoT and smart home applications. However, the Waveshare board still provides solid connectivity options, making it suitable for general development needs.

Display Features

The Waveshare board incorporates a 1.47-inch LCD display with a resolution of 172×320 pixels and 262K colours. This feature allows for the development of applications that require visual output, making it particularly valuable for projects involving user interfaces.

On the other hand, the IoTCrazy board does not include an onboard display, focusing instead on wireless performance and compatibility with various development environments. If visual feedback is essential for your project, the Waveshare board is undoubtedly the better option. However, if the display is not a priority, the IoTCrazy board remains a strong contender.

Storage and Memory

In terms of memory, the Waveshare board is equipped with 512KB SRAM, 384KB ROM, 16MB Flash, and 8MB PSRAM, providing ample storage for efficient operation and program execution. This extensive memory setup is advantageous for complex applications that require significant storage space.

Conversely, the IoTCrazy board offers 520KB of SRAM, which is sufficient for many IoT applications but may limit more demanding projects. Users needing extensive memory for their applications may find the Waveshare board more suitable, while those engaged in simpler tasks can comfortably use the IoTCrazy board.

Development Environment and Ease of Use

Both boards feature compatibility with popular development environments. The Waveshare board is built for advanced HMI applications, while the IoTCrazy board is fully compatible with the Arduino IDE and ESP-IDF, making it beginner-friendly for those familiar with these platforms.

The IoTCrazy board's compatibility with Arduino IDE allows users to prototype and code quickly, which can be particularly beneficial for newcomers. However, the Waveshare board’s focus on advanced functionalities may appeal more to experienced developers seeking to create sophisticated applications.

Build Quality and Durability

When it comes to build quality, the Waveshare board is designed with multiple I/O interfaces, a TF card slot, and a battery charging module, enhancing its versatility. The IoTCrazy board is packaged in an anti-static bag with foam protection, ensuring durability during transport, which is essential for maintaining the board’s integrity.

While both boards are built to last, the Waveshare board's additional features may provide an edge in terms of versatility and application range. However, the IoTCrazy board’s quality soldering and careful packaging ensure it is also a reliable option for developers.

Which should you buy?

Choosing between the Waveshare ESP32-S3 1.47inch LCD Display Development Board and the IoTCrazy ESP32-WROOM-32U Dev Board with 3dBi Antenna ultimately depends on your project needs. If your project requires a built-in display, advanced processing capabilities, and extensive memory for complex applications, the Waveshare board at C$31.99 is the better choice.

Conversely, if you’re looking for a budget-friendly option focused on enhanced wireless connectivity and ease of use, the IoTCrazy board priced at C$18.99 is an excellent fit. Consider your specific requirements and budget to determine which board aligns best with your development goals.
