Description:
1. In the F401 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.
2. 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.
3. The GND is changed to 5V B9 5V GND, which can directly connect a small steering gear without additional wiring and reduce development time.
Features:
1. 84Mhz Freq，64KB RAM, 256KB ROM, 36 I/0 MAX
2. 25MHZ high-speed crystal & 32.768Khz 6PF low-speed crystal
3. Flash pads have been reserved to provide USB DiSk && FATFFS routines
4. The internal 10K resistor of BOOT is pulled down. Press the BOOT key to enter the ISP mode.
5. Factory-programmed breathing light & USBCDC test procedure
Package Include:
1 x STM32 System Minimum Board
