How to Design a Pedal PCB Like a Pro

Updated: Aug 29, 2023

I am starting a series on designing a PCB! For this project, I am going to use the Marshall Blues Breaker as a platform for these "lessons." My main tool for designing this PCB is www.EasyEDA.com which is free to everyone and has a great auto-router feature :-)


As a general guideline, here is the approach:

  1. Define the requirements. The first step in PCB design is to define the requirements of the circuit board. This includes the number of components, the type of components, the power requirements, the size of the board, and the environmental conditions in which the board will be used.

  2. Create a schematic diagram. Once the requirements have been defined, the next step is to create a schematic diagram of the circuit. This diagram shows the electrical connections between the components of the circuit.

  3. Place the components on the board. Once the schematic diagram has been created, the next step is to place the components on the board. This is done using PCB layout software. The software allows the designer to place the components in the most efficient way possible, taking into account the size of the board, the power requirements, and the environmental conditions.

  4. Route the traces. Once the components have been placed on the board, the next step is to route the traces. The traces are the conductive pathways that connect the components together. The designer must route the traces in a way that minimizes interference and ensures that the circuit will function properly.

  5. Generate the Gerber files. Once the traces have been routed, the final step is to generate the Gerber files. The Gerber files are the files that are used by the PCB manufacturer to create the circuit board.

Here are some additional tips for designing a circuit board PCB:

  • Use high-quality components. The quality of the components used in a circuit board can have a significant impact on the performance and reliability of the board.

  • Follow good design practices. There are many good design practices that can help to ensure the success of a PCB design. These practices include using the correct tools and software, following design guidelines, and testing the design thoroughly.

  • Get help from a professional. If you are not familiar with PCB design, it is a good idea to get help from a professional. A professional can help you to ensure that your design is correct and meets all of your requirements.

I hope this helps! Check back with updated videos.

If you'd like to download my exact project files as seen in this video, you may download them from https://oshwlab.com/prosboarder/open-source-blues-breaker . You may need to create an account with EasyEDA before the "open in editor" button is available. Alternatively, you may build the circuit board all by yourself by following along in real time!
