GitHub wasn’t built for hardware.
So we built Circuit World.
An AI-native EDA + MCAD platform for designing, iterating, collaborating, versioning, and manufacturing hardware in one browser.
You don’t have to start every design from scratch.
Start with one of 8,800+ existing boards, build on it, and iterate with AI from PCB to mechanical assembly. Then send it straight to manufacturing.

Pokémon cards are cool. Pokémon PCBs are cooler.
it's open source btw: heypcb.ai/world/b/3cd3810ac0…

time for the fourth recap of @finagotchi for Colosseum, let it ride!

Image to PCB.
heypcb.ai/art
Put any image on a PCB.
Introducing HeyPCB Art.
1. Upload any image
2. Choose how it looks
3. Download manufacturing-ready Gerber files
Turn anything into PCB silkscreen art.

hardware design shouldn't require years of learning.
we want anyone with an idea to be able to turn it into a real circuit board.
describe what you want, design it with AI, edit it yourself, and export real KiCad files.
here's a little bunny PCB 🐰

Open to new opportunities! 🛠️
I’m currently available for full-time roles, freelance contracts, and project collaborations.
If you have an exciting build, need hands-on technical work, or want to collaborate, my DMs are open. Let’s connect!

We built Figma for hardware.

Open-source hardware is everywhere. Understanding it is still hard.
So we built HeyPCB Comment.
Point at any part of a circuit board, ask a question, and let Inky explain how it works.
1. Ask questions on schematics, PCBs, and 3D models
2. Get answers based on the actual design
3. Turn comments into hardware changes with AI
From understanding hardware to making it your own.
Point at it. Ask.

Just finished an analog-only water quality sensor board.
No microcontroller on it just clean 0–5 V outputs for:
• Temperature (LM35)
• Humidity
• pH (with high-impedance amp)
• TDS / Conductivity
• Turbidity
70 × 55 mm, fully routed, DRC clean.
Yes, we give everyone free AI credits.
Try HeyPCB for free. If you like the results, subscribe. If you don't, no pressure.
Either way, we want you to build something real.
a lot of people still don't realize HeyPCB is free to get started.
1. sign up, claim your username, and get 100% free AI credits
2. explore and download 11,000+ open-source circuit boards
3. fork any design, edit it with AI, and build together in your browser
no credit card required. free design exports. no vendor lock-in.
we believe hardware should be open and accessible to everyone. we're still early, still improving, and always listening to feedback on how we can make HeyPCB better for everyone.
so go build something real!

Hardware discovery is stuck in 2010.
We think it deserves something better.
So we built a completely different way to explore open-source hardware.
11,000+ designs. One swipe at a time.

Just finished designing a fully galvanically isolated bridge PCB for my ESP32 ⚡️
Safe high-voltage inverter monitoring (voltage + current feedback) with split ground domains and optocouplers so the micro doesn't fry.
DRC clean, 0 errors, ready for fab! 🛠️
@heypcbai is completely changing the game 🚀
The GOAL is to make circuit development feel effortless, and honestly, seeing how smoothly everything flows right now, they are already nailing it.
Hardware design has never felt this seamless. Who is Your Baddie
