The STM32F411 / 401 microcontroller belongs to the STM32 Dynamic Efficiency series.

These devices are entry-level products of the high-performance F4 series, with a main frequency of up to 100 / 84MHz.

They also have a wealth of peripherals, DSP instructions and floating-point units to expand the range of applications.

(The 401CC dismantled by POS is used somewhere)


characteristic:


The downloader and the core board are independently powered to facilitate separate use

The on-board J-LINK OB based on STM32F103T8 supports downloading and online debugging.

Use USB TYPEC interface, more convenient to use.

Onboard one user LED, two user buttons (with hardware debounce), and two voltage dividers can be quickly embedded into the design prototype.

user's guidance:


Correctly solder the upper half of the JLINK components except the single-chip microcomputer according to the schematic diagram and PCB. Note that R7 is not soldered and left blank.

Power on and measure whether the usb voltage is 5v, and whether the LDO outputs 3.3v

Welding on F103T8 MCU

Power on, if not burned, connect another xxlink writer in the upper right corner of the board, and burn the JLINKOB.bin in the attachment

Plug and unplug usb to see if JLINK has been recognized in the device manager
