Explorer STM32F4 development board information

The Explorer STM32F4 development board chooses STM32F407ZGT6 as the MCU. This chip is very powerful in the STM32F407. Its resources include: integrated FPU and DSP instructions, and has 192KB SRAM, 1024KB FLASH, 12 16-bit timers, 2 32-bit timers, 2 DMA controllers (a total of 16 channels), 3 SPI, 2 full-duplex 12S, 3 IIC, 6 serial ports, 2 USB (support HOST/SLAVE), 2 CAN, 3 12-bit ADC, 2 12-bit DAC, 1 RTC (with calendar function), 1 SDIO interface, 1 FSMC interface, 1 10/100M Ethernet MAC controller, 1 camera interface, 1 hardware random number generator, and 112 general IO ports. The configuration of this chip is very powerful, and many functions have been significantly improved compared to STM32F1, such as the speed of FSMC. The refresh speed of F4 can reach 3300W pixels/second, while the speed of F1 is only about 500W. Now I have collected some schematics, PCB, source code and document manuals to share with you.
