STM32 Hardware Design

I designed this STM32 breakout board in Altium Designer with the following features:

• For STM32s with LQFP-64 package

• Access to all functional pins through headers

• USB power supply with 5V to 3V3 regulator

• 16 MHz High Speed External (HSE) crystal

• STDC14 (STLinkV3) debug connector

• Power indicator LED and an LED connected to PB13

• Reset button

I designed the schematics hierarchically for more organisation and readability: 

After finishing the design, I had the board manufactured with all the components. 

I tested my boards by trying them with an I2C temperature sensor in this project. They proved to be working perfectly! 

Here is an interactive 3D PDF showing the 3D model of the PCB with components. (software that supports 3D content in PDF, such as Adobe Reader is needed)
