Meet The Founder

Hi, I'm Dario Fresu

Like many designers, my first real approach to professional circuit board design started right after finishing my studies in electronics.


This is also when I realized I really had no clue about designing a professional printed circuit board (PCB) from scratch.

And let's be honest, this is where many of us designers start.

It's kind of funny because when I was a kid, I played with electronics, and I even got a degree in Electronics. I knew a lot about electrical circuits, but I still didn't know how to make a professional PCB.

I did study a lot of theory during my studies, that's for sure, but I had no clue how to apply it to design my circuits. 


Just so you understand, I'm not talking about making simple breadboard circuits or basic "Arduino" one-layer boards. Those can be fun, but you wouldn't want one of those circuits to be the 'brain' controlling an airplane or a car, would you?

No, I wanted to build professional circuits, circuits like motherboards with processors, motor controllers, radios, management systems, and all the cool electronics that companies integrate into their awesome products. 

As you can imagine, going from designing a breadboard to designing a motherboard is no easy task. Or at least it wasn't for me.

But after many years of trying and learning, reading lots of books, taking courses, getting certificates, and making many more PCB designs, it finally started to make complete sense.

Now finally, the theory I had studied in the early days was starting to bring results.

Fast-forward to today:

  • I have collaborated with a variety of companies, ranging from emerging startups to established industry leaders, guiding them in launching their products. This includes working as a Technical Expert with esteemed institutions like ETH Zurich (among the top 10 best universities in the world), enriching my expertise in PCB design and development.

  • I have provided consultancy to clients through challenges in Electromagnetic Compatibility, Signal IntegrityPower Integrity, and Printed Circuit Board Design.

  • I have led teams and projects, and mentored interns and students, blending theory with practical experience in circuit design.

  • Additionally, I share knowledge and educate through social media, with 16K subscribers across platforms, and over 2.8K members in the PCB Hackers LinkedIn Community.

Why am I telling you all this?

Because I want you to succeed and avoid the same errors I made. I'm sharing everything I've learned about circuit design on this platform and program.

These methods have worked for me and many others, so I know they can work for you too. These are the same methods that allowed me to increase 10X my salary and provide a hundred times more value to my clients.
