High - Performance STM32F4 Development Board with 84MHz CPU, 64KB RAM & 256KB Flash (STM32F401CCU6)

🔧 Overview: The HZWDONE STM32F401 STM32F411 Development Board is a powerful and versatile platform designed for developers, engineers, and hobbyists who wish to explore the capabilities of the STM32 ARM Cortex-M4 microcontroller series. This board features the STM32F401CCU6/CDU6 and STM32F411CEU6 models, operating at a clock speed of 84MHz, and is equipped with 64KB of RAM and 256KB of flash memory for efficiently handling complex applications.

🛠️ Crystal Oscillators: The development board includes a 25MHz high-speed crystal oscillator for precision timing and performance, as well as a 32.768kHz low-speed crystal oscillator, optimized for power-efficient operations such as real-time clock applications.

💍 Environmentally Friendly Design: Starting from version V3.0, this board adopts a lead-free manufacturing process, further enhanced by gold-plated pin headers for improved connectivity and durability, ensuring a more eco-friendly solution.

⚡ Programming Support: The HZWDONE development board is designed for flexibility with support for both MicroPython and Arduino programming environments. With compatible MicroPython firmware readily available, users can easily configure and deploy applications, while Arduino enthusiasts can refer to the GitHub repository for comprehensive libraries and resources.

🔘 Enhanced User Interaction: Boards from version V1.3 and beyond come equipped with three dedicated buttons: the reset button, the BOOT0 button, and a user-defined button, allowing for streamlined operation and ease of use during development.

ISP Mode Entry: The board offers two methods to enter ISP mode for firmware updates:

• Method 1: Press and hold the BOOT0 button and the reset button while powering on the board. Release the reset button first, then the BOOT0 button after 0.5 seconds.
• Method 2: With the power off, hold down the BOOT0 button and release it 0.5 seconds after powering on.

🔘 DFU Mode: To enter DFU mode, simply connect the board to a computer using a USB cable. If the device is not recognized, it may be necessary to slightly warm the chip (up to 25°C) and then re-attempt entering ISP mode.

⚡ Serial Port Connection: For serial communication, utilize a USB-to-serial connection to interface with PA9 and PA10 on the core board, which facilitates direct communication without the need for additional hardware.

💍 Software Compatibility: The STM32CubeProg software is recommended for firmware downloads, simplifying the process by requiring only a TYPE-C data cable—no additional drivers, debuggers, or USB-to-serial converters are necessary.

🔘 Entering HID Bootloader: After writing to the application (APP), users can easily boot into HID Bootloader mode by holding the KEY button and pressing the reset button. When the LED C13 flashes, release the KEY button to enter this mode.
