diymore LoRa V4 ESP32 Development Board 0.96" Display vs Waveshare 8-Ch Ethernet Relay Module

Overview of the Products

In this comparison, we will examine the diymore LoRa V4 ESP32 Development Board 0.96" Display and the Waveshare 8-Ch Ethernet Relay Module. The diymore board is priced at £45.99, while the Waveshare module is available for £56.99. Both products cater to different applications, with the diymore board focusing on wireless communication and the Waveshare module designed for industrial relay control.

Design and Build Quality

The diymore LoRa V4 board features an integrated 0.96-inch OLED display which allows for real-time data visualisation without the need for additional hardware. This is particularly beneficial for developers looking for an all-in-one solution. In contrast, the Waveshare 8-Ch Ethernet Relay Module is built with an ABS rail-mount case, providing durability and ease of installation, especially in industrial environments. While both devices have robust constructions suited to their functions, the diymore board's integrated display offers a distinct advantage for visual feedback during development.

Functionality and Use Cases

The diymore LoRa V4 board excels in long-range wireless communication with a transmit power of 28±1dBm, making it ideal for applications such as smart home IoT devices and outdoor GPS trackers. It incorporates features like solar charging and a GNSS interface, enhancing its versatility for remote installations. Conversely, the Waveshare module is designed for industrial applications, supporting Modbus RTU/Modbus TCP protocols and providing eight channels of relay control. This makes it particularly suitable for scenarios requiring reliable and stable relay operations in smart agriculture or industrial control systems.

Performance and Connectivity

In terms of performance, the diymore board offers a remarkable sensitivity of -137dBm, which is crucial for establishing reliable connections over long distances. This is especially important for building extensive LoRa networks in urban environments. The Waveshare relay module, on the other hand, supports both passive and active digital input and incorporates a bi-directional optocoupler isolation for enhanced stability. Its capability to operate on a wide range of DC 7~36V power input further adds to its flexibility in various industrial applications.

Power Management

Power management is a strong point for the diymore LoRa V4 board, which features optimized battery management and a low sleep current of just 20μA. This allows it to function effectively in battery-powered remote devices, particularly those relying on solar energy. In comparison, the Waveshare relay module supports Power over Ethernet (PoE), offering a seamless power supply solution for installations without direct access to power outlets. Each product’s approach to power management makes it well-suited for its intended use cases, though they cater to different market needs.

Ease of Use and Installation

The diymore board provides a complete development experience, with compatibility maintained across previous versions, ensuring ease of transition for developers familiar with earlier models. It also offers an integrated antenna for stable Wi-Fi/Bluetooth connectivity, which simplifies setup. In contrast, the Waveshare relay module is designed for straightforward installation in industrial settings, complete with an ABS enclosure and features like flash-on and flash-off functions, which add to its user-friendliness. Both products are designed with ease of use in mind but serve distinctly different audiences.

Community and Support

Support is crucial for developers and users alike. The diymore board offers access to an electronic version of the user guide, along with a responsive support system for those needing assistance. Given its popularity within the IoT community, users can find ample resources and forums for troubleshooting and innovation. Meanwhile, Waveshare provides documentation on the Modbus protocols and has a reputation for reliability in industrial applications. Both brands appear committed to customer support, though the diymore board may have an edge in community-driven content due to its broader appeal in the maker space.

Which should you buy?

Choosing between the diymore LoRa V4 ESP32 Development Board and the Waveshare 8-Ch Ethernet Relay Module ultimately depends on your specific requirements. If you are looking for a powerful development board for IoT projects with long-range communication capabilities, the diymore board at £45.99 presents a compelling option. However, for those who need a robust solution for industrial relay control with features like Modbus support and PoE capabilities, the Waveshare module at £56.99 is the better choice. Each product excels in its domain, making your decision dependent on whether you prioritise wireless communication or industrial automation.
