Press and hold theKEY button, click thereset button, LED C13flashes, release theKEY buttonto enterHow to enter HID Bootloader after writing to APP Software: STM32CubeProg. Serial port mode: use USB to serial port to connect PA9 and PA10 of the core board DFU mode: just use the data cable to connect to the computer, if there is a problem of unrecognized, you can properly heat the chip (25 ° C), and then re-enter the ISP mode Method 2: Hold down the BOOT0 key when power is off, and release the BOOT0 key 0.5S after power on Method 1: Press and hold the BOOT0 button and the reset button under the power-on state, then release the reset button, and release the BOOT0 button after 0.5 secondsHow to enter ISP mode Boards with version V1.3 and above have 3 buttons, reset button, BOOT0 button, and user buttons.Support Arduino programming, see Github https://github.com/stm32duino/Arduino_Core_STM32 for detailsSupport MicroPython programming, provide available MicroPython firmware, see the link for configuration files, but do not provide technical answers!Flash pads have been reserved and USBDisk && FATFFS routines are providedV3.0 version began to use lead-free process, the pin header is gold-plated pin header, more environmentally friendly25MHZ high speed crystal oscillator & 32.768Khz 6PF low speed crystal oscillatorSTM32F401CCU6 3.0/STM32F411CEU6 3.0 Development BoardSTM32F401CCU6 core board V3.0Freq. 84Mhz ROM:256KB RAM:64KBSTM32F411CEU6 core board V3.0Freq. 100MHZ ROM:512KB RAM:128KB
The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
