key word： Simple experimental circuit board
Imitate some popular MicroPython card , Most of them are single-chip computers 、 The debugging interface and necessary circuits are compactly packaged on a circuit board , External passing distance 100mil The pin of can be conveniently connected with other circuit boards 、 Bread board connection , Complete the basic test experiment . Compared with PLUS-F3270 Experiment board , This kind of experimental circuit board can build various test circuits more flexibly .
Here is with SD The design schematic diagram and PCB Territory . What's interesting is that , In order to adapt to rapid plate making based on heat transfer ,PCB The layout is specially laid on one side , Only used less 0 Ohmic resistance acts as a jumper , The proposed experimental circuit board can be made on single-sided copper clad laminate .
▲ chart 1.1.1 CPU circuit 
▲ chart 1.1.2 CPU Peripheral circuits Here is PCB Territory , It is suitable for rapid plate making on one side . If you use double-sided board , The circuit can be made more exquisite .
▲ chart 1.2.1 PCB Territory The following is the printed circuit board after welding . It can be inserted into the panel board to build the experimental circuit .
▲ chart 1.2.2 After welding, insert it on the bread board for experiment
