BSROBOTIC WT32-ETH01 Development Board Ethernet - ESP32 Development Board Module vs Official Raspberry Pi Pico Board

Price Comparison

When it comes to price, the Official Raspberry Pi Pico Board offers a more budget-friendly option at C$19.96, while the BSROBOTIC WT32-ETH01 Development Board is priced at C$29.18. This represents a difference of C$9.22. If you're looking for a cost-effective solution for basic projects, the Raspberry Pi Pico is the clear winner. However, the additional investment in the BSROBOTIC board may be justified for users who require its advanced networking capabilities.

Performance Overview

The BSROBOTIC WT32-ETH01 Development Board features a dual-core Xtensa 32-bit LX6 MCU, designed for high performance and efficiency, while the Official Raspberry Pi Pico Board is equipped with a dual-core Arm Cortex-M0+ processor running at 133 MHz. The Pico operates at a lower clock speed compared to the WT32-ETH01 but offers a flexible architecture with a 264KB on-chip SRAM. Users needing robust processing power and versatility may find the WT32-ETH01 more appealing, particularly for applications involving Wi-Fi and Bluetooth connectivity.

Connectivity Options

Connectivity is a key differentiator between these two boards. The BSROBOTIC WT32-ETH01 excels in this area, supporting Wi-Fi, Ethernet, and Bluetooth, along with various serial protocols. It provides the ability to establish TCP/UDP connections and supports firmware upgrades via network connections. In contrast, the Official Raspberry Pi Pico Board offers a more limited range of connectivity options, with 26 GPIO pins and standard interfaces like UART, SPI, and I2C. For projects that demand extensive networking capabilities, the WT32-ETH01 stands out as the superior choice.

Development Flexibility

The BSROBOTIC WT32-ETH01 is designed with developer flexibility in mind. It allows for secondary development, enabling users to tailor the board to their specific needs. This is further enhanced by its support for multiple data transmission modes, including TCP Client and Server configurations. While the Raspberry Pi Pico also supports drag-and-drop programming, its primary focus is on ease of use for beginners rather than extensive customisation. Thus, the WT32-ETH01 is likely better suited for experienced developers seeking more control over their projects.

Temperature Range and Industrial Use

The BSROBOTIC WT32-ETH01 boasts an industrial-grade operating temperature range of -40 to +85 degrees Celsius, making it suitable for applications in harsh environments. This is a significant advantage for users needing reliability in extreme conditions. The Official Raspberry Pi Pico, on the other hand, operates within a more standard range of -20 to +85 degrees Celsius. For projects that require resilience under tough conditions, the WT32-ETH01 clearly has the upper hand.

Programming and Software Support

Both boards offer unique programming capabilities. The BSROBOTIC WT32-ETH01 supports various protocols and can be programmed via AT commands, which may appeal to advanced users familiar with networking protocols. The Raspberry Pi Pico simplifies the programming process with its drag-and-drop functionality over USB, targeting beginners and educational environments. Depending on your skill level and project requirements, one may find the programming experience on either board more advantageous.

Power Supply and Efficiency

The Official Raspberry Pi Pico operates at a flexible input power range of 1.8 to 5.5 volts DC, which is beneficial for battery-powered applications. It also features low-power sleep and dormant modes, enhancing its efficiency for long-term projects. Conversely, the BSROBOTIC WT32-ETH01 does not specify its power requirements as clearly, but its design focuses on high performance and versatility. For projects prioritising power efficiency and battery life, the Raspberry Pi Pico may be the better option.

Which should you buy?

When deciding between the BSROBOTIC WT32-ETH01 Development Board and the Official Raspberry Pi Pico Board, consider your project requirements carefully. The WT32-ETH01 is ideal for advanced users who need high performance, extensive connectivity options, and the ability to operate in extreme temperatures, albeit at a higher price of C$29.18. Conversely, the Raspberry Pi Pico is a more budget-friendly option at C$19.96, great for beginners and those focused on standard applications with moderate connectivity needs. Ultimately, your choice should reflect your specific needs in terms of performance, price, and project complexity.
