STM32F407 ARM Processor-based Hardware Interface Module Designing

This project involves designing a 4-layer PCB for an STM32F407 ARM-based hardware interface module using Altium Designer 16.

The work covers schematic creation, custom component library development, PCB layout, and manufacturing file generation.

This project was completed in 2021 as a task assigned during my internship at Premium International.

🛠 Design Process

1. Research & Preparation

   • Studied multilayer PCB concepts, THM vs SMT, EMC, and PCB testing methods
   • Reviewed STM32F407 datasheet, identified pin configurations & peripheral requirements

2. Schematic Design

   • Created separate schematic sheets for power, communication, microcontroller configurations, i/o and memory configurations.
   • Added JTAG, USB, voltage regulator, and crystal oscillator circuits
   • Used custom libraries for missing components

3. PCB Layout

   • Defined board shape and set 4-layer stackup
   • Placed components on both sides of PCB
   • Adjusted routing widths for connectors

4. Manufacturing Output

   • Generated assembly drawings, drill files, and 3D views
