In the F4 series, the chip is the cheapest, even cheaper than some F1, and crushed F1 on the main frequency, and has a floating-point arithmetic module, the IO port contains all the basic functions. Therefore, it is possible to provide a learning platform with a very high cost performance for beginners. In practical applications, it is not because the computing power is insufficient, and the IO port is incomplete and hinders development.

BOOT Settings are changed from jumper to button to reduce the installation trouble by pressing BOOT0 and NRST, releasing NRST to access serial port download, DFU download, providing ST official multi-in-one STM32 Cube Programmer burning software. These do not come with the bootloader already installed. You will need either an STLink dongle or USB to TTL module, we have both in store.
The STM32F411CEU6 cam be used for basic makecode development, if you would like the link on how to do it send us a message.
The USB connection is Type C
