diymore 3PCS ESP32-S3 WiFi Bluetooth Mini Development Board Module Dual-Core Pro vs Waveshare ESP32-S3 ETH Development Board

Overview of the diymore 3PCS ESP32-S3 WiFi Bluetooth Mini Development Board

The diymore 3PCS ESP32-S3 WiFi Bluetooth Mini Development Board is a compact and versatile development module powered by a dual-core processor. With a current price of £14.99 for three units, it offers an economical option for developers seeking to create Wi-Fi and Bluetooth applications. The board features a robust Xtensa 32-bit LX7 dual-core processor, clocked at 240 MHz, which provides sufficient processing power for various tasks. Additionally, it supports 2.4GHz Wi-Fi and Bluetooth 5, making it suitable for a range of IoT projects.

Equipped with 512KB SRAM, 384KB ROM, 4MB Flash, and 2MB PSRAM, the diymore board has ample memory for most applications. Its unique punch hole design and integrated ceramic antenna simplify integration into custom projects. Moreover, the board boasts 34 GPIOs for flexible peripheral configuration, enhancing its usability in diverse scenarios.

Overview of the Waveshare ESP32-S3 ETH Development Board

The Waveshare ESP32-S3 ETH Development Board is a more feature-rich option, priced at £27.99. This board also utilises the Xtensa 32-bit LX7 dual-core processor, delivering the same clock speed of 240 MHz. However, it distinguishes itself with additional memory, including 8MB PSRAM and 16MB Flash, providing significantly more storage capacity than the diymore board.

One of the standout features of the Waveshare board is its onboard W5500 Ethernet chip, which enables a 10/100Mbps network connection via SPI interface. This makes it particularly advantageous for applications requiring stable internet connectivity. Furthermore, it includes a camera interface compatible with popular modules, enhancing its utility for projects involving image processing.

Design and Build Quality

In terms of design, the diymore board is notable for its compact size and efficient layout, optimising space while providing essential features. The punch hole design facilitates seamless integration into custom base plates, making it ideal for DIY enthusiasts.

Conversely, the Waveshare board offers a more expansive design to accommodate its additional features, such as the PoE module and camera interface. This board's build quality is robust, with an onboard antenna and the flexibility to switch to an external antenna if needed. The presence of a USB Type-C port for power supply and programming further adds to its user-friendliness.

Connectivity Options

The connectivity options of both boards are impressive, but they cater to different needs. The diymore board supports 2.4GHz Wi-Fi and Bluetooth 5, making it suitable for a variety of wireless applications. Its extensive GPIO options provide flexibility in peripheral configurations.

On the other hand, the Waveshare board takes connectivity a step further with its onboard W5500 Ethernet chip, allowing for wired internet connections. This feature is particularly beneficial for projects that require reliable connections, such as those involving data transmission or remote monitoring. The inclusion of both wired and wireless connectivity options makes the Waveshare board a versatile choice for developers.

Memory and Storage

When it comes to memory and storage, the two boards exhibit distinct differences. The diymore board includes 512KB SRAM, 384KB ROM, 4MB Flash, and 2MB PSRAM. While this is sufficient for many applications, developers working on more intensive projects may find it limiting.

In contrast, the Waveshare board offers a more generous configuration with 512KB SRAM, 384KB ROM, 8MB PSRAM, and 16MB Flash. This substantial increase in memory and storage capacity enables more complex applications, including those requiring significant data processing or storage. The additional memory also allows for better multitasking capabilities, making the Waveshare board a more future-proof option.

Power Management Features

Power management is another critical consideration when selecting a development board. The diymore board supports flexible power management options, allowing developers to achieve low power consumption across various scenarios. This feature is particularly advantageous for battery-powered projects or applications requiring long operational periods.

The Waveshare board also includes power management features, notably the option for Power over Ethernet (PoE). This IEEE 802.3af-compliant feature enables the board to receive power through the Ethernet cable, simplifying installations and reducing the need for separate power supplies. This capability makes the Waveshare board particularly appealing for projects in remote or hard-to-reach locations.

Development Flexibility and Compatibility

Both boards offer significant development flexibility, but their compatibility features set them apart. The diymore board's 34 GPIOs allow developers to configure peripheral functions based on their project requirements. Its small form factor is advantageous for custom projects where space is limited.

In contrast, the Waveshare board provides extensive compatibility with various peripherals, including an onboard camera interface for image capture. It also supports the Pico header, enhancing its expandability. The added TF card slot for external storage further increases its versatility, making it suitable for a broader range of applications.

Which should you buy?

Choosing between the diymore 3PCS ESP32-S3 WiFi Bluetooth Mini Development Board and the Waveshare ESP32-S3 ETH Development Board depends largely on your specific project needs. If you're looking for an economical option with essential features for simple wireless applications, the diymore board at £14.99 is an excellent choice. However, if your project requires more advanced capabilities, such as reliable Ethernet connectivity, greater memory, and compatibility with peripherals like cameras, the Waveshare board at £27.99 offers a compelling advantage. Ultimately, your decision should align with the complexity and requirements of your intended applications.
