Compatible with WildFire Challenger F429V1 development board

Replica of Wildfire Challenger V1 core board
    . I had nothing to do, so I bought a Wildfire Challenger V1 baseboard on a certain fish website, and also bought a STM32F429IGT6 microcontroller. Now the price of F429 has dropped to less than 100, so I just drew one. The price of Challenger on Taobao is really expensive, 400+. I downloaded the information of Wildfire Challenger from the official website, drew it according to the schematic diagram, and then drew the PCB according to Brother Huo's PCB layout. Although the boards I drew are not exactly the same, at least they are irrelevant and the drawings are ugly. Those who are capable can modify them.
    The wiring is not very standardized. I have only drawn some small boards before. After drawing, I printed the board and tried it. I pasted the MCU first, then burned the port, and connected SWD to see if it could be recognized normally. Then I found that it really could not be recognized. I panicked all of a sudden. I thought there was something wrong with the drawing of the board and the MCU could not recognize it. Later, I observed the schematic diagram and found that there was an inductor connecting VCC and VDDA. If this inductor is not soldered, VDDA will not be powered, and the MCU cannot run. Naturally, the MCU cannot be recognized.
    After a morning of hard work, I used a soldering station, an air gun, and an electric soldering iron to finally paste the board. Sure enough, poor students have a lot of stationery!
 The following is
a picture of the finished product. Try turning on the red light
and then the green light .
The front view
is successfully lit, and then tried the button, which is also normal. There should be no rollover.
