6-Pack ESP-WROOM-32 Development Board vs Waveshare ESP32-S3 ETH Development Board

Price Comparison

The 6-Pack ESP-WROOM-32 Development Board is priced at C$45.99, while the Waveshare ESP32-S3 ETH Development Board is slightly cheaper at C$42.99. This C$3 price difference may seem minimal, but for buyers looking to purchase in bulk, the cost-effectiveness of the 6-Pack could be a significant factor. Given that each board in the 6-Pack offers versatility for various projects, the overall investment might be justified for those needing multiple units. However, for those interested in a single board solution, the lower price of the Waveshare board makes it an attractive option.

Performance Capabilities

In terms of processing capabilities, the Waveshare ESP32-S3 ETH Development Board features an Xtensa 32-bit LX7 dual-core processor that operates at 240 MHz. This represents a marked improvement over the ESP32 ESP-32S NODEMCU dual-core processor found in the 6-Pack ESP-WROOM-32, which operates at a calculation speed of 600 DMIPS. While specific MHz values for the ESP-WROOM-32 aren't provided, the LX7 processor’s architecture is typically more efficient than that of the LX6. Thus, for applications requiring higher performance, the Waveshare board may be the better option.

Memory and Storage

When it comes to memory, the Waveshare ESP32-S3 ETH Development Board boasts a robust configuration with 512KB SRAM, 384KB ROM, 8MB PSRAM, and 16MB Flash memory. In contrast, the 6-Pack ESP-WROOM-32 Development Board specifies having 520 KB of SRAM but lacks detailed information on additional memory types. This significant difference in memory capacity means that the Waveshare board is better suited for more complex applications that require extensive data handling and storage.

Connectivity Options

The Waveshare board offers extensive connectivity options, including an onboard W5500 Ethernet chip for 10/100Mbps network connectivity and the ability to switch to an external antenna for enhanced wireless performance. In comparison, the 6-Pack ESP-WROOM-32 offers various interfaces such as SPI, SDIO, I2C, and UART, but does not have dedicated Ethernet capabilities. For developers prioritising wired connections or needing to manage multiple devices on a network, the Waveshare board provides a clear advantage.

Expansion Capabilities

The Waveshare ESP32-S3 ETH Development Board excels in expansion capabilities, featuring a TF card slot for external storage and compatibility with a variety of peripheral interfaces. It also includes an onboard camera interface, allowing for image and video capture with compatible cameras. Meanwhile, the 6-Pack ESP-WROOM-32, while versatile in its support for various firmware like microPython and FreeRTOS, does not specify similar expansion features. For developers looking to integrate additional hardware or expand their projects, the Waveshare board could be the more practical choice.

Ease of Use

Both development boards are designed with ease of use in mind, but they cater to slightly different audiences. The 6-Pack ESP-WROOM-32 supports a range of firmware, including nodelua and microPython, making it accessible for hobbyists and beginners. Its compact design and small size of 58 * 28 * 12mm make it easy to embed in other products. On the other hand, the Waveshare ESP32-S3 ETH Development Board comes with a USB Type-C port that simplifies power supply, programming, and debugging, which may appeal more to professional developers seeking convenience in their workflow.

Target Audience

The 6-Pack ESP-WROOM-32 Development Board is ideal for hobbyists and educational settings where multiple units are advantageous for learning or prototyping. Its cost-effective pricing at C$45.99 for six boards makes it a budget-friendly option for individuals or teams starting with IoT projects. Conversely, the Waveshare ESP32-S3 ETH Development Board, priced at C$42.99, targets developers looking for high-performance capabilities and expanded functionalities, making it suitable for more advanced applications requiring efficient data processing and connectivity.

Which should you buy?

In conclusion, the choice between the 6-Pack ESP-WROOM-32 Development Board and the Waveshare ESP32-S3 ETH Development Board largely depends on your specific needs. If you're looking for an affordable option for multiple projects, the 6-Pack offers great value and easy integration into various applications. However, if you require enhanced performance, extensive memory, and superior connectivity options, the Waveshare board stands out as the superior choice. Ultimately, understanding your project requirements will guide you to the best decision between these two capable development boards.
