NOW SPONORED BY PCBWay
It all started in 2023. I was tinkering with some electronics when my little brother asked me about logic gates. I tried to explain it to him, but I realized that while the concept is quite easy, understanding it takes some time. This sparked an idea in me. I wanted to create a learning tool that helps to truly understand logic gates.
I set out to design a hands-on kit to help with learning about logic gates. I envisioned a project where you wouldn’t just read about truth tables, but actually see them in action as doing is the best way to learn.
After a lot of trial and error, Logic Gates was born—board that made learning interactive and intuitive. As the project evolved, I kept listening to feedback from the community. It was amazing to see other beginners and enthusiasts joining in, offering suggestions and tweaks that made the kit even better. The feedback that was gathered helped to design a better revision of the board that allows for almost to buy a fully working product.
The brains for this board is STM32G030K6T6, it was chosen as it has the neccecery amount of IOs and allows for minimization of components therefore reducing the BOM cost. This also allows to easily do quality assurance, as the MCU can turn on the LEDs, this allows the check that everything works as intended. In marketing material, “LED animation” is mentioned when turing on the board but now you know what the idea behind it really is.
Recently, I’ve been working on a major update. Here PCBWAY helped me out with prototyping. I received a new batch of boards featuring an updated MCU and a overall better design that now includes a repositioned battery holder. No more tedious hand soldering—everything is now designed for seamless assembly at the PCB manufacturer. This update has not only optimized the process but also made it more scalable, bringing the cost per board down significantly.
I have submitted the deisgn to be part of the PCBWAY competition. I am happy for all of the views, likes and everything the community has given me. Thank you!
Shout out to PCBWAY for helping this new revision come to life. I am quite happy with the quality of the PCB. The yellow color, feels very smooth to touch which is quite unusual thing to expect from a PCB.
Looking back, what started as a simple conversation with my brother has grown into a passion project. So far, many universities have shown interest in the product, and I hope that this tool can accelerate the learning process for logic gates.
