STM32F750N8H6 polaris development board

The board provides over ten standard interfaces, allowing convenient experimentation and development with various peripherals. We adopt a core board + baseboard form factor, where one baseboard can be used to learn multiple MCUs, reducing redundant investments. Many resources on the board can be flexibly configured to meet usage requirements under different conditions. We have brought out 112 I/O ports, greatly facilitating expansion and usage. The onboard one-click download feature eliminates the hassle of frequently setting B0 and B1, enabling STM32 development with just a single USB cable. The board features a high-performance audio codec chip, a six-axis sensor, a Gigabit Ethernet port, an ambient light sensor, and various interface chips to meet diverse application needs.
