Official Raspberry Pi Pico Board vs Waveshare ESP32-S3 ETH Development Board

Introduction to the Boards

When comparing the Official Raspberry Pi Pico Board and the Waveshare ESP32-S3 ETH Development Board, it's essential to consider their unique features and applications. The Raspberry Pi Pico is priced at C$12.16, while the Waveshare board is more expensive at C$42.99. This price difference signifies varying capabilities and target audiences for each product.

Form Factor and Design

The Raspberry Pi Pico is compact, measuring 21 mm × 51 mm, making it ideal for projects where space is a premium. In contrast, the Waveshare board does not specify its dimensions, but it includes a PoE module option, which may increase its footprint. The Pico's small size allows it to fit seamlessly into various devices, while the Waveshare's design focuses on versatility and expandability.

Processing Power

The processing capabilities differ significantly between the two boards. The Raspberry Pi Pico features a dual-core Arm Cortex-M0+ processor that operates at 133 MHz, suitable for simple tasks and hobbyist applications. On the other hand, the Waveshare ESP32-S3 boasts a more powerful Xtensa 32-bit LX7 dual-core processor, running at 240 MHz. This higher clock speed provides the Waveshare board with better performance for demanding applications, including those requiring real-time processing.

Memory and Storage

Memory is another area where the two products diverge. The Raspberry Pi Pico comes with 264 KB on-chip SRAM and 2 MB on-board QSPI Flash, sufficient for basic projects. Meanwhile, the Waveshare ESP32-S3 is equipped with a more substantial memory configuration, featuring 512 KB SRAM, 384 KB ROM, 8 MB PSRAM, and 16 MB Flash memory. This allows for greater data handling and storage capabilities, making the Waveshare board better suited for larger projects that require more resources.

Connectivity Options

When it comes to connectivity, the Waveshare ESP32-S3 excels with its integrated 2.4 GHz Wi-Fi and Bluetooth 5 capabilities, allowing for wireless communication in IoT applications. The onboard W5500 Ethernet chip also provides a 10/100 Mbps network port, enhancing its connectivity options. The Raspberry Pi Pico, however, only features GPIO pins for interfacing, lacking built-in wireless capabilities. This makes the Waveshare board a more versatile choice for projects needing robust connectivity.

Peripheral Support

Peripheral support varies between the two boards, significantly impacting their usability. The Raspberry Pi Pico includes 26 GPIO pins, with three analogue inputs and various communication protocols like SPI and I2C. It offers a rich set of peripherals for hobbyists. In contrast, the Waveshare ESP32-S3 provides more extensive peripheral support, including an onboard camera interface compatible with mainstream cameras. This makes it more suitable for projects requiring image capture and processing.

Power Requirements

Power requirements for these boards differ as well. The Raspberry Pi Pico operates on a voltage range of 1.8–5.5V DC, making it adaptable to various power sources. Meanwhile, the Waveshare ESP32-S3 supports Power over Ethernet (PoE), following the IEEE 802.3af standard when using the optional PoE module, adding convenience for installations requiring minimal cabling. This feature can make the Waveshare board more advantageous for certain applications where power management is crucial.

Programming and Development Ease

For developers, the choice of programming languages can affect usability. The Raspberry Pi Pico supports programming in C and MicroPython, catering to a broad range of skill levels. Its drag-and-drop programming method simplifies the initial setup process. Conversely, the Waveshare ESP32-S3 does not specify programming languages in the provided data, but its advanced features likely cater to more experienced developers seeking to exploit its full potential. This could make the Raspberry Pi Pico more appealing for beginners.

Which should you buy?

Choosing between the Official Raspberry Pi Pico Board and the Waveshare ESP32-S3 ETH Development Board largely depends on your specific needs. If you're looking for an affordable, compact option for basic projects, the Raspberry Pi Pico at C$12.16 is a solid choice. However, if you need advanced processing power, extensive memory, and superior connectivity options for complex applications, the Waveshare board, despite its higher price of C$42.99, may be worth the investment. Consider your project requirements carefully to make an informed decision.
