📒 Overview

This is a STM32F411RET6 mini development board, which can be used for AI development, UI development, digital power control board, etc. And can even be used for your other projects.

>span class="md-meta-i-c md-link">OV-Watch，many copy people said that the device is very difficult to weld, secondary development is not convenient, In addition, I also plan to deploy some AI-related things on STM32 and do a tutorial, so the FryPi fried chicken pie was born. This development board is not only suitable for beginners, but also for advanced developers, and advanced demos may require a certain knowledge reserve.

Also, the reason for choosing this MCU is also because the STM32F411REU6 can perfectly replace the CEU6 of the original smart watch project, and there are F411 hardware options in simulink.

🚀 Features

• MCU use STM32F411RET6, Cortex-M4 core with DSP and FPU, 512 Kbytes of Flash memory, 100 MHz CPU, ART Accelerator.
• External SPI Flash can be welded in addition.
• Rich Demo: smart watch, >span class="md-plain">, handwritten number recognition, develop with matlab, simulink HIL development and so on.
• Leave the port for external expansion board. (For example, the top demo .gif showed is pluged the Cam expansion board into the Core board)
• >span class="md-plain">The pin map of the FryPi is shown as follows. At present, only few I/O ports are used for LCD and touch screen, etc.

📦 Get Started

After the development board is welded, once the template demo is donloaded, if there is no problem with the hardware, the phenomenon is: then the TypeC corresponding to the serial port is connected to the computer, L2 will blink, press the Key to switch mode, L2 blink frequency will change, and the upper PC will receive the mode information;

If the TypecC connected to the USB of the development board is connected to the computer, the computer will appear formatted U disk, and then after formatting, it will simulate a U disk.
