• Hi, I am Toan Nguyen, I learned how to using Kicad for design PCB from 1 week ago.
• I learn Kicad from some video in Youtube in Phil'sLab, thank channel shared all Knowledge about Kicad for Work.
• This mini project is course in Udemy of Phil'sLab is shared and free. If you have time, you can join the course.

• Total Schematic for STM32F103xxx
• Power supply:

I use ASM117-3.3 as IC main for LDO voltage because:

Current Output of ASM1117 suitable with 1A, Fixed Voltage is 3.3V for VDD of IC STM32F103.

I using micro USB type B, current 10-100mA, Input voltage 5Vdc

Now, we can see example-ASM1117 of manafactory to design for this block:

I using capacitor 0.1-10uF to filter input voltage, capacitor 47-1000uF to filter output voltage. LED is added to display Voltage 3.3V whether or not.

• MCU

All design of MCU was referenced in internet with keyword "stm32f103c8 kit schematic", you can find schematic for this design with above keyword.

• Layout

• 3D

Goodluck!
