3pcs STM32F401 Development Board STM32F401CCU6 STM32F4 Learning Board Geekcreit for Arduino - produc

Why Choose 401 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. 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. Features: - 25MHZ high speed crystal oscillator 32.768k low speed crystal oscillator - STM32F401CCU6 core board 64KB RAM 256KB ROM - 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. - The GND is changed to 5V B9 5V GND, which can directly connect a small steering gear without additional wiring and reduce development time. Package Included: 3 x STM32F401 Development Board STM32F401CCU6
