STM32F407Z system board

Overview

The smallest system board made using the STM32F407ZET6 chip is compatible with the STM32F407ZGT6 chip, and the board size is 60*80mm.
There are 32.768KHz crystal oscillator and 8MHz crystal oscillator circuit, AMS1117-3.3 5V to 3.3V circuit, reset circuit, Micro-B interface, reserved CH340N serial port chip, pin header leads to ST-LINK, serial port download interface and 110 IO ports.
Both BOOT0 and BOOT1 of the system board are connected to ground with a 10k resistor. Before using the serial port to download, short BOOT0 to 3.3V, and then disconnect it after downloading. After soldering the pin header, the system board can be inserted into the holes with a spacing of 2.54mm. on the board.
The base corresponding to the system board has been designed in Board2.
The video uses the serial port experimental program of Punctual Atom's F407.
The layout of the CH340N chip has been optimized and updated.
