first You can flash the firmware for the first time like this, press and hold the DuPont male connector (the prerequisite is that you have soldered it and inserted the downloader and DIY stlink into the computer). If that doesn't work, just solder the wire.
The firmware download tool, firmware, and firmware upgrade tools are all in the attachment.
 
 
 
Finally, I would like to say that the
          cables on the board are pulled randomly, but they can be used. All devices are packaged in relatively large 0805 packages, which is more convenient for manual soldering (just apply solder paste, place the device, and blow with an air gun). Currently, there is no problem in normal use of the test, and the firmware upgrade can also support the latest version. When choosing the main control chip, the flash needs to be at least 128K. STM32F03CBT6 is definitely no problem. This test used Hezhou’s Air32F103CBT6 and all functions are normal. If Air32F103CCT6 is tested and it doesn’t work, don’t use it. Other chips have not been tested. Family members are welcome to comment. Leave a message in the area which chips can be used and which ones cannot be used.
