2. Flash pad has been reserved and USBDisk&&FATFFS routines are provided
3 Jumper caps can be used directly without installation. BOOT0 internal 10K resistance pull-down
4 Factory has burned breath lamp &&USBCDC test procedure.
5 Provide available MicroPython firmware, configuration file see link does not provide technical answers!
6 Adjust the direction of the jump cap if it cannot be installed. Because the jump cap is wide on one side and narrow on the other.
7 version V1.3 board with 3 buttons, reset key, BOOT0 key, user key.
About software download, firmware download, there are a lot of information online, online can not find the time to ask customer service, cultivate their learning ability, data search ability.
V1.3 Serial port download and DFU download: Serial port connect PA9, PA10 (connect usb in dfu mode) hold down the BOOT0 key and reset key, then
Release the reset key, and release the BOOT0 key 0.5 seconds later to download the serial port or DFU. The corresponding software is flymcu or CubeProg.
Jump version download: BOOT0 is high, BOOT1 is high, go to the serial port download or DFU download, the software is the same as above.
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.
