Official Raspberry Pi Pico Board vs Waveshare ESP32-S3 1.47inch LCD Display Development Board

Overview of the Products

The Official Raspberry Pi Pico Board is designed for a wide range of applications, while the Waveshare ESP32-S3 1.47inch LCD Display Development Board focuses on advanced HMI applications. The Raspberry Pi Pico is priced at C$12.16, making it an affordable entry into microcontroller development, whereas the Waveshare board is significantly more expensive at C$31.99. This price difference reflects their respective capabilities and target uses.

The Raspberry Pi Pico features a dual-core Arm Cortex-M0+ processor running at 133MHz, suitable for basic to intermediate projects. In contrast, the Waveshare board boasts a more powerful Xtensa 32-bit LX7 dual-core processor that operates at up to 240MHz, making it more suitable for complex applications requiring graphical interfaces and advanced connectivity.

Performance and Processing Power

When it comes to performance, the Waveshare ESP32-S3 has a clear advantage with its dual-core processor running at 240MHz compared to the Raspberry Pi Pico's 133MHz. This higher clock speed allows the Waveshare board to handle more demanding tasks, particularly those involving real-time data processing or graphical output.

The Raspberry Pi Pico, while less powerful, offers sufficient performance for many hobbyist projects. Its dual-core Arm Cortex-M0+ processor is designed for low-power applications, allowing for a longer battery life in projects that don't require high processing power. Users needing to support advanced applications may find the Raspberry Pi Pico's performance limiting compared to the capabilities of the Waveshare board.

Memory and Storage

In terms of memory, the Waveshare ESP32-S3 significantly outperforms the Raspberry Pi Pico. The Waveshare board features 512KB of SRAM, 384KB of ROM, 16MB of Flash, and 8MB of PSRAM, providing ample storage for application code and data. This extensive memory capacity enables the board to efficiently run complex programs and store larger datasets.

Conversely, the Raspberry Pi Pico comes with 264KB of on-chip SRAM and 2MB of on-board QSPI Flash. While this is adequate for simpler applications, developers may find it restrictive when working on larger projects. The storage capabilities of the Waveshare board make it more suitable for applications that require significant data handling or graphical interfaces.

Connectivity Options

The connectivity options are where the Waveshare ESP32-S3 stands out. It supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), ensuring robust wireless communication for IoT projects. This versatility is critical for applications involving remote data transmission or device interconnectivity.

On the other hand, the Raspberry Pi Pico lacks built-in wireless capabilities, focusing instead on wired connections through its 26 GPIO pins. While it does include various interfacing options like UART, SPI, and I2C, users looking to implement wireless communication will need to incorporate additional modules. The Waveshare's connectivity options make it a more appealing choice for modern applications requiring seamless wireless integration.

Display Features

The Waveshare ESP32-S3 includes a 1.47-inch LCD display with a resolution of 172×320 and the capability to display 262K colours. This built-in display is ideal for developing graphical interfaces, making it suitable for applications like HMI systems, where visual feedback is essential.

In contrast, the Raspberry Pi Pico does not feature a display, which limits its immediate application for projects requiring user interaction through visual output. While the Pico can be connected to external displays, this adds complexity and cost to projects that could otherwise benefit from an integrated solution like that offered by the Waveshare board.

Development Environment

Both the Raspberry Pi Pico and the Waveshare ESP32-S3 support popular programming environments, but they cater to different user needs. The Raspberry Pi Pico can be programmed in C and MicroPython, making it accessible for beginners and hobbyists who appreciate its straightforward drag-and-drop programming method.

The Waveshare ESP32-S3, being focused on more advanced applications, may require a steeper learning curve due to its extensive features and capabilities. However, it also provides rich libraries for development, particularly for those working with HMI applications. This makes it a better choice for developers with prior experience looking to build sophisticated projects.

Power Requirements

The power requirements of these two boards reflect their design philosophies. The Raspberry Pi Pico operates at a voltage range of 1.8–5.5V DC, allowing for flexibility in power sources, and features low-power sleep and dormant modes to conserve energy.

In contrast, the Waveshare ESP32-S3 is designed to efficiently manage power with low-power modes, but it generally requires a stable power supply due to its higher performance specification. This difference is crucial for developers working on battery-powered applications, as the Raspberry Pi Pico's lower power consumption may be more beneficial for such scenarios.

Which should you buy?

Choosing between the Official Raspberry Pi Pico Board and the Waveshare ESP32-S3 1.47inch LCD Display Development Board largely depends on your project requirements. If you are a beginner looking for an affordable microcontroller for simple projects, the Raspberry Pi Pico at C$12.16 offers excellent value with its straightforward programming and low power consumption. However, if your project demands advanced features such as high processing power, extensive memory, and built-in wireless capabilities, the Waveshare ESP32-S3 at C$31.99 is the superior choice. Its enhanced performance and display features make it ideal for developing complex applications, particularly those requiring user interaction.
