Use Altium Designer software to draw a circuit schematic diagram and PCB diagram of a stm32 minimum system

Operating environment

The operating environment is Altium Designer 18.1.7
Altium Designer acquisition and installation tutorial click here

Draw the circuit schematic diagram of the smallest system of stm32

Create project

Open Altium Designer, click file–new–project–integrated library,

change the project name and save it

under the project, create a new sch library and pcb library

, save the project after creation, and rename the created library

Chip PCB packaging

Back to the pcb library interface, select tools and

click next on the next interface. On the next interface, select the following and

fill in the package data according to the figure.

After that, click next until finish. The final effect is:

open the stm32 minimal system.SchLib, do the following, add rectangles, as the chip

to be packaged, add pins to the chip, and

add pins. The effect is as follows.

Then perform the chip according to the following figure After changing the

final effect as follows

, perform the following operations

to return to the sch library, double-click to modify the component name, note that the question mark needs to be input in Chinese

** Back to the project interface, right-click on the project, and select the first check to see if the

component library is generated successfully

Custom component PCB packaging

Right-click to add a blank component in the pcb library edit box,

double-click to change its name,

click to place the trace

, double-click the trace after placement is complete, and modify the current layer to TOP Overlay

Then place it like this

Then put the arc

After that, the current layer is also changed to TOP Overlay

Place the fill

Double-click to fill to change its current layer to TOP Overlay

Finally place the pad

Packaging of custom components SCH

Open SCH library, select add under the window

Start placing lines

Then operate the production library file as above and double-click to rename it

Right-click the project and select the first item to check for errors and generate library files

Draw the minimum system schematic diagram of stm32

Then create a new project, right-click [Schematic] to create a schematic drawing interface to

place components, click Libraries on the right, and then click installed, you can add the library you created,

then you can see the library you created by

double-clicking to place a chip

placement line Extend each pin and

click to place the network label, double-click and write the corresponding network name

after connecting to the VBAT1 port, modify the name to VOUR,

add VCC as follows ,

add GND to 3.3V ,

and search for the ground terminal in the official library to add RES, 10kΩ

The complete chip is as follows,

and the schematic diagram of the final placement of the components is as follows

Identify each circuit part of the schematic, click "A" in the upper menu bar to add a text box, and drag it to the specified part, such as "decoupling circuit", etc. The

final effect is as follows
