Waveshare ESP32-S3 1.47inch LCD Display Development Board vs STM32F103C8T6 ARM STM32 Minimum System Development Board 2PCS

Overview of the Waveshare ESP32-S3 and STM32F103C8T6

The Waveshare ESP32-S3 1.47inch LCD Display Development Board is a high-performance option designed for advanced HMI applications, while the STM32F103C8T6 ARM STM32 Minimum System Development Board is a more basic solution aimed at beginners. With significant differences in features and pricing, each product serves different user needs.

The Waveshare board is priced at C$31.99, offering extensive functionalities including a high-resolution LCD display and wireless connectivity. In contrast, the STM32 board is budget-friendly at C$12.99, catering to those seeking an entry-level microcontroller experience without the bells and whistles of more advanced features.

Processing Power

When it comes to processing capabilities, the Waveshare board outshines the STM32F103C8T6. The ESP32-S3 features a high-performance Xtensa 32-bit LX7 dual-core processor that can run at speeds of up to 240MHz, making it suitable for complex applications. This dual-core setup allows for efficient multitasking and enhanced performance in demanding scenarios.

On the other hand, the STM32F103C8T6 is equipped with a single-core ARM Cortex-M3 CPU, operating at a frequency of 72MHz. While this is sufficient for simpler tasks, users requiring more processing power will find the Waveshare board to be the better choice for resource-intensive applications.

Memory and Storage

Memory capacity is another critical differentiator between these two development boards. The Waveshare ESP32-S3 boasts an impressive configuration with 512KB SRAM, 384KB ROM, and 16MB Flash, along with an additional 8MB PSRAM. This abundant memory makes it ideal for projects that require running multiple tasks or storing larger datasets.

Conversely, the STM32F103C8T6 offers a more limited memory arrangement with 64K of Flash memory and 20K of SRAM. While this is adequate for basic development tasks, those looking to work on more sophisticated projects will find the memory limitations of the STM32 board a significant drawback compared to the Waveshare option.

Connectivity Options

The Waveshare ESP32-S3 is designed with modern connectivity in mind, supporting 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5.0 (LE), all facilitated by an onboard antenna. This feature allows for seamless wireless communication, making it an excellent choice for IoT applications and devices that require remote interaction.

In contrast, the STM32F103C8T6 does not offer built-in wireless capabilities, which may limit its applicability in certain projects. Users of the STM32 board will need to incorporate additional modules for connectivity, potentially increasing the overall cost and complexity of their projects.

Display Capabilities

One of the standout features of the Waveshare ESP32-S3 is its integrated 1.47-inch LCD display with a resolution of 172×320 pixels and the ability to display 262,000 colours. This capability allows for rich user interfaces and interactive projects, making it a strong candidate for developers focusing on visual applications.

The STM32F103C8T6, however, lacks any built-in display, which means that users wanting visual output will need to connect external displays. This requirement could complicate setups for those who prefer an all-in-one solution, making the Waveshare board more appealing for visually-driven projects.

Additional Features

The Waveshare ESP32-S3 offers additional features that enhance its functionality, including a 6-axis IMU for motion sensing and gesture detection, a TF card slot for external storage, and a battery charging module. These features make it versatile and suitable for various applications, from robotics to gaming.

In contrast, the STM32F103C8T6 focuses on providing essential microcontroller functionalities. It includes a USB interface for power and communication but lacks the additional features that can significantly simplify development and expand project possibilities, limiting its appeal for advanced users.

Price Comparison

Price is a significant factor when choosing between the Waveshare ESP32-S3 and the STM32F103C8T6. The Waveshare board is priced at C$31.99, reflecting its advanced features and capabilities. This price point may be justified for developers who require a robust platform for complex applications.

On the other hand, the STM32F103C8T6 is available at a much lower price of C$12.99. This makes it an attractive option for hobbyists and students who are new to embedded systems and programming. However, the lower price comes with limitations that may hinder more ambitious projects.

Which should you buy?

Deciding between the Waveshare ESP32-S3 and the STM32F103C8T6 ultimately depends on your specific needs and budget. If you require advanced processing power, extensive memory, built-in connectivity, and a display, the Waveshare board is worth the investment at C$31.99. However, if you are a beginner or working on simpler projects where cost is a crucial factor, the STM32F103C8T6 at C$12.99 may be the right choice. Each board serves different purposes, so consider your project requirements carefully before making a decision.
