Homemade STM8 Development Board

A simple development board for STM8 was made by thermal transfer, with only the programming and reset functions. The drawing time is long, mainly without the TSSOP20 package. The production time is very short, and it will be done in more than an hour. It seems that before the photosensitive plate, the photosensitive dry film, the photosensitive wet film is going to the evil road. There are many steps in the long time, no heat transfer is quick. And this time the line width of 12mil is no problem, not a break.
