[DIY] Homemade stm32 development version

Said before:

    I know there are many similar products on the market, but I still chose to make one myself. It even took me nearly two days to draw the board, because this board has a feature that no other similar board on the market has: IO port. It is led out sequentially, which is also the reason why wiring is difficult, so the board area is larger than others.

The advantages are as follows:
1. IO sequential lead-out
2. Type-C interface lead-out and direct support for serial port
3. The peripherals only include the serial port (UART2) and a two-color light.
4. The high-cost HT7833 used in LDO has extremely low static power consumption.
5. Provide test routines and simple technical support.

It is very suitable for students with low budget and many peripheral modules to get started,
or for engineers to develop and test.

           The file was designed using AD . There will be some deviations when opening it with Easy EDA. If you need to create a board, it is recommended to directly use the .PcbDoc file without (ASCII) field in the attachment .
