Stark Reactor (low)

Based on the modification of the LED infinite dimming open source project of a guy from Kaiyuan Square, thank you!
I forgot who it is, please @ him again when you have time or send him a private message. I'm too busy
to post two pictures right now. Since my chip is a domestic substitute, I forgot that it can only be programmed with st-link, so there is no programming interface reserved.,, it makes me cry even if I talk about it too much, but I finally programmed it.
The boot animation will not be modified and will be adjusted later, and new features will be added later.
 
Update log:
demo1.0 (Mark 1.0) (2022.11.1) is
the first version of the design, with some pins reserved for subsequent function expansion.
Mark 2.0 (2022.11.13)
is based on the first version and leads to all the pins of the microcontroller (basic pins). End)
Added 32.768Mhz crystal oscillator, more complete functions.
All pins will be expanded by wiring.
Additional test holes of BOOT0 and BOOT1 will be added for downloading and programming. (Explanation, this version changes the USB serial port programming and boot to the CH340 programming module, which is led out by the cable, leaving test holes for the convenience of friends who do not want to use the CH340 burning module to build the board) CH340 download core (S Tucker Soul Injector) is as follows:

Mark 2.1 (2022.11.20)
Optimize some packages
 
and use M2. 5+6+5 copper pillars
