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

Overview of the Products

In the realm of development boards, the Waveshare ESP32-S3 1.47inch LCD Display Development Board and the Official Raspberry Pi Pico W Board stand out as compelling options. The Waveshare board is priced at C$31.99, while the Raspberry Pi Pico W offers a more budget-friendly option at C$21.63. Both boards cater to different needs and application scenarios, making them suitable for developers at various skill levels.

The Waveshare board features a high-performance Xtensa 32-bit LX7 dual-core processor that operates at up to 240MHz, ideal for advanced human-machine interface (HMI) applications. In contrast, the Raspberry Pi Pico W is equipped with a dual-core Arm Cortex-M0+ processor, clocked at 133MHz, which may appeal to those looking for a simpler and more straightforward platform for IoT projects.

Performance Comparison

The Waveshare ESP32-S3 boasts a superior processing speed of 240MHz compared to the Raspberry Pi Pico W's 133MHz. This difference in clock speed can significantly impact performance, especially for applications that demand more processing power. The ESP32-S3's dual-core architecture is designed to handle complex tasks, making it suitable for applications like real-time data processing and advanced HMI interactions.

On the other hand, the Raspberry Pi Pico W's dual-core Arm Cortex-M0+ processor still offers commendable performance for everyday tasks and IoT applications. With 264KB of SRAM and 2MB of on-chip QSPI Flash, it provides enough resources for typical use cases, although it may fall short in scenarios requiring high computational intensity.

Connectivity Options

When it comes to connectivity, the Waveshare ESP32-S3 is equipped with 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), ensuring reliable wireless connections for various applications. The inclusion of an onboard antenna further enhances its connectivity capabilities, making it a strong candidate for modern IoT solutions.

The Raspberry Pi Pico W also features 2.4GHz 802.11n wireless LAN, allowing it to connect effortlessly to Wi-Fi networks. While both boards support wireless communication, the additional Bluetooth capabilities of the Waveshare board may provide an edge in applications requiring multiple wireless protocols.

Memory and Storage

The Waveshare ESP32-S3 offers 512KB of SRAM, 384KB of ROM, 16MB of Flash, and 8MB of PSRAM, providing ample storage for efficient program execution and data handling. This extensive memory configuration is particularly beneficial for complex applications that require significant memory resources.

In contrast, the Raspberry Pi Pico W comes with 264KB of on-chip SRAM and 2MB of on-board QSPI Flash. While this is adequate for basic tasks, it may pose limitations for more demanding projects. For developers who require substantial memory for their applications, the Waveshare board clearly has the advantage.

Display Features

One of the standout features of the Waveshare ESP32-S3 is its integrated 1.47-inch LCD display, which boasts a resolution of 172×320 pixels and supports 262K colours. This display makes it particularly suitable for projects that require visual feedback or user interaction through a graphical interface.

The Raspberry Pi Pico W, however, does not come with a built-in display. While it can interface with external displays, the lack of an integrated screen may require additional components, potentially increasing project complexity and cost. For developers prioritising display integration, the Waveshare board offers a convenient solution.

Input/Output Interfaces

The Waveshare ESP32-S3 features multiple I/O interfaces, including a TF card slot for external storage, making it versatile for various applications that demand connectivity with additional peripherals. The presence of a battery charging module and low-power modes also enhances its usability in portable projects.

Conversely, the Raspberry Pi Pico W offers 26 GPIO pins, including three analogue inputs, along with various communication protocols such as UART, SPI, and I2C. This extensive set of interfaces makes it adaptable for a wide range of projects, but users may need to invest in additional components for external storage solutions, which are conveniently included in the Waveshare board.

Power and Operating Conditions

The Waveshare ESP32-S3 operates efficiently with a wide input voltage range and includes low-power modes, making it ideal for battery-powered projects. Its capabilities in this area are essential for applications where power consumption is a critical concern.

The Raspberry Pi Pico W also supports a power input range of 1.8–5.5V DC and features low-power sleep modes, making it suitable for IoT applications where power efficiency is vital. While both boards are designed with power efficiency in mind, the Waveshare’s extended functionalities in this aspect, such as battery charging, may provide a more comprehensive solution for mobile applications.

Which should you buy?

Choosing between the Waveshare ESP32-S3 1.47inch LCD Display Development Board and the Official Raspberry Pi Pico W Board ultimately depends on your specific project needs. If you require higher processing power, integrated display, and extensive memory, the Waveshare board at C$31.99 is undoubtedly the better option. However, for those on a budget or focusing on simpler IoT tasks, the Raspberry Pi Pico W at C$21.63 offers solid performance and flexibility. Assessing your project's requirements will guide you to the right choice for your development needs.
