Waveshare ESP32-S3 1.47inch LCD Display Development Board vs Waveshare ESP32-S3 ETH Development Board

Price Comparison

The price difference between the Waveshare ESP32-S3 1.47inch LCD Display Development Board and the Waveshare ESP32-S3 ETH Development Board is significant. The LCD Display Development Board is priced at C$31.99, while the ETH Development Board costs C$42.99. This means that the ETH Development Board is C$11.00 more expensive than its counterpart. The price disparity reflects the additional features and capabilities offered by the ETH Development Board, making it crucial to consider whether those features justify the higher cost.

Performance and Processing Power

Both development boards feature the high-performance Xtensa 32-bit LX7 dual-core processor, capable of running at 240MHz. This ensures that both boards deliver robust processing capabilities suitable for various applications. However, the Waveshare ESP32-S3 ETH Development Board includes more memory options, such as 512KB SRAM, 384KB ROM, 8MB PSRAM, and 16MB Flash memory. This extra memory can enhance performance, especially for applications that require more extensive data handling or programming, making the ETH Development Board potentially more effective for complex projects.

Connectivity Features

Connectivity options differ significantly between the two boards. The Waveshare ESP32-S3 1.47inch LCD Display Development Board supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) with an onboard antenna for reliable wireless connectivity. In contrast, the Waveshare ESP32-S3 ETH Development Board also supports 2.4GHz Wi-Fi and Bluetooth 5 but adds an onboard W5500 Ethernet chip that allows for 10/100Mbps network connections through a SPI interface. This additional Ethernet capability can be crucial for projects requiring stable and fast wired network connections, making the ETH Development Board a better choice for certain applications.

Display and User Interaction

When it comes to user interaction, the Waveshare ESP32-S3 1.47inch LCD Display Development Board stands out with its 1.47-inch LCD display featuring a resolution of 172×320 and 262K colours. This display is ideal for advanced Human-Machine Interface (HMI) applications, allowing developers to create visually engaging interfaces for their projects. The ETH Development Board, however, does not include a display, focusing instead on networking capabilities and peripheral connectivity. For projects where visual output is essential, the LCD Display Development Board is undoubtedly the more suitable option.

Peripheral Compatibility

Peripheral compatibility is another area where the two boards differ. The Waveshare ESP32-S3 1.47inch LCD Display Development Board comes equipped with multiple I/O interfaces, a TF card slot for external storage, and a battery charging module. It also includes a 6-axis IMU for motion sensing and gesture detection, making it versatile for various applications. On the other hand, the Waveshare ESP32-S3 ETH Development Board features an onboard camera interface that is compatible with OV2640, OV5640, and other mainstream cameras, as well as a USB Type-C port for power supply, program downloading, and debugging. Depending on the project’s needs, one board may be more advantageous than the other.

Storage Options

Storage capabilities also vary between the two development boards. The Waveshare ESP32-S3 1.47inch LCD Display Development Board is equipped with 16MB Flash and 8MB PSRAM, which provides ample storage for efficient operation and program execution. Conversely, the Waveshare ESP32-S3 ETH Development Board features the same 16MB Flash memory but only 8MB PSRAM. This makes the LCD Display Development Board potentially better suited for applications that require extensive data storage or larger programs, giving it an edge in storage capacity.

Power Options

Power management is a critical consideration in development boards, especially for projects requiring portability. The Waveshare ESP32-S3 1.47inch LCD Display Development Board comes with a battery charging module, allowing it to be powered by batteries, which is ideal for mobile applications. The Waveshare ESP32-S3 ETH Development Board, while offering a Power over Ethernet (PoE) option for powering the device via network cabling, does not have a built-in battery solution. This difference may affect usage scenarios, with the LCD Display Development Board being more suitable for portable or battery-operated projects.

Which should you buy?

Choosing between the Waveshare ESP32-S3 1.47inch LCD Display Development Board and the Waveshare ESP32-S3 ETH Development Board ultimately depends on your specific project needs. If your application requires a display for user interaction, enhanced storage capabilities, and a battery charging solution, the LCD Display Development Board at C$31.99 is the better option. However, if you need robust networking features with Ethernet connectivity and compatibility with external peripherals like cameras, the ETH Development Board at C$42.99 might be worth the additional investment. Assessing the features against your project requirements will guide you to the right choice.
