With 512KB of SRAM, 384KB of ROM, 16MB of Flash, and 8MB of PSRAM, this board provides significant memory resources for complex applications. Additionally, it incorporates multiple I/O interfaces, a full-speed USB port, and an onboard TF card slot for expanded storage options. This makes the Waveshare a powerful tool for developing Human-Machine Interfaces (HMIs) and other ESP32-S3 applications.

Overview of the STM32F103C8T6

The STM32F103C8T6 ARM STM32 Minimum System Development Board is a more budget-friendly option, retailing at C$12.99 for a package of two boards. It is built around the ARM Cortex-M3 core, operating at a frequency of 72MHz, which is suitable for basic embedded applications. The board provides access to all I/O resources and includes essential circuits such as a crystal oscillator and USB interface for easy connectivity.

With 64KB of Flash memory and 20KB of SRAM, it offers sufficient resources for simpler projects. The inclusion of a SWD debug interface is beneficial for developers needing to debug their applications efficiently. The STM32F103C8T6 is ideal for those who require a straightforward development environment without the need for advanced graphical capabilities.

Performance Comparison

In terms of performance, the Waveshare ESP32-S3 significantly outshines the STM32F103C8T6. The Waveshare operates with a dual-core 240MHz processor, which allows it to handle more demanding tasks compared to the STM32's single-core 72MHz performance. This difference in processing power enables the Waveshare to run complex applications and GUI programs more effectively.

Moreover, the ESP32-S3's support for Wi-Fi and Bluetooth 5.0 gives it a distinct advantage in connectivity, making it suitable for Internet of Things (IoT) applications. In contrast, the STM32F103C8T6 serves well for simpler projects that do not require extensive networking features.

Memory and Storage

The memory capabilities of both boards are noteworthy, but they cater to different project needs. The Waveshare ESP32-S3 boasts an impressive combination of 16MB Flash and 8MB PSRAM, alongside 512KB SRAM and 384KB ROM. This extensive memory allows developers to create more intricate applications and store larger datasets directly on the board.

On the other hand, the STM32F103C8T6 has a modest 64KB of Flash memory and 20KB of SRAM, which is adequate for basic embedded applications but may limit more ambitious projects. For developers focused on creating applications that require significant memory resources, the Waveshare offers a compelling advantage.

User Interface and Interaction

The Waveshare ESP32-S3 is equipped with a 1.47-inch LCD screen, enabling developers to create interactive user interfaces with ease. This feature is particularly useful for projects that involve user interaction, as it allows for the smooth execution of graphical programs using libraries like LVGL.

In contrast, the STM32F103C8T6 does not come with an onboard display, which may pose limitations for projects requiring visual feedback or interaction. Developers working on applications that need a GUI will find the Waveshare’s display capabilities to be a significant benefit, making it the preferred choice for more visually-oriented projects.

Connectivity Options

Connectivity is another area where the Waveshare ESP32-S3 excels. With integrated 2.4GHz Wi-Fi and Bluetooth 5.0 capabilities, it allows for seamless communication with a wide variety of devices and cloud services. This makes it particularly suitable for IoT applications where wireless connectivity is essential.

Conversely, the STM32F103C8T6 relies on a more traditional USB interface for power and communication, which limits its flexibility in terms of wireless connectivity. For developers looking to create connected devices, the Waveshare provides essential features that are increasingly important in today's tech landscape.

Development and Debugging

The STM32F103C8T6 includes a SWD debug interface that simplifies the debugging process, making it easier for developers to troubleshoot their applications. This feature is particularly beneficial for those working on simpler projects where debugging is essential.

While the Waveshare ESP32-S3 does not explicitly mention a debug interface, its development environment supports robust debugging tools, allowing developers to streamline their workflow. For complex projects requiring advanced debugging capabilities, both boards have their strengths, but the STM32 may be perceived as more accessible for beginners.

Which should you buy?

Deciding between the Waveshare ESP32-S3 and the STM32F103C8T6 ultimately depends on your project requirements. If you need a high-performance board with extensive memory, advanced connectivity options, and a built-in LCD for user interaction, the Waveshare ESP32-S3 is the clear winner at C$28.99. However, if you are looking for a cost-effective solution for simpler embedded projects, the STM32F103C8T6 offers good value at C$12.99 for two boards. Each board has its unique strengths, so consider your specific needs before making a choice.
