STM32

Currently, the professional version of the open source version does not have a preview of the design drawing. You can directly click "Open Editor" in the upper right corner, so that you can see the schematic diagram and PCB, and the release time refers to the creation time of the project.
This board restores 99% of the peripherals of the Atomic Elite Edition, removes some of the more useless functions, and adds some peripherals.
Compared with the elite version of Zhengdian Atom, this board has the following improvements: 1. The virtual U disk interface and USB-to-serial port adopt the currently common type-c interface, which is more convenient to use. 2. The download indicator light of the USB to serial port is added, and the download process can be clearly observed. 3. The USB to serial port uses CH340C as the main chip, which avoids the need to connect an external crystal oscillator when using CH340G as the main chip. 4. Added a gyroscope module interface 5. Added a wireless ESP8266 module interface 6. Added a Zhongjingyuan 1.3-inch 7-pin OLED screen interface 7. Added full-color LED lights to achieve various display effects 8. Removed the capacitive buttons 9. Replaced some frequently switched jumper caps with switches, which is more convenient. 10. The SWD download method is adopted. Compared with JTAG, there are fewer wirings and there is no obvious difference in performance in all aspects. 11. Wait,
the BOM table below provides purchase links for most of the components in the schematic diagram. The unmarked resistors and capacitors are all in 0603 packages. All components were purchased from Uxin Electronics in a certain store. Relatively common.
I made an extra one when I made it myself. You can add QQ3162224107 to purchase it. If you have any questions about this board, you can also contact me (indicate the purpose of your visit).
All functions of the board have been verified and can be used normally. Regarding the wiring of the board, I I’m not very proficient, if there are any unreasonable things, please feel free to communicate!
