PCBBrew is an AI electronics designer for makers. Tell it what you want to build: it picks the parts, draws the KiCad schematic, places and routes the board, writes and simulates the firmware, and hands you the production files.
Free during the beta · invites sent in batches
No CAD skills needed to start, and real KiCad files when you want to take over.
"An ESP32 thermometer with an OLED and an alarm LED." Add photos of the modules you already own: the assistant reads them, asks what's missing and proposes the architecture.
Schematic, PCB, 3D, parts list with datasheets. Electrical rule checks, design rule checks and SPICE simulation run automatically, and the firmware runs in a simulator in your browser.
Download Gerber files, BOM and an interactive assembly guide for any PCB fab, and flash the firmware to your board over USB, straight from the browser.
Every project is a KiCad 10 project built from the official libraries, checked against KiCad's own netlist. Open it in KiCad whenever you like.
Compact two-layer boards with ground planes, mounting holes and connectors on the edge, routed automatically and verified with KiCad's design rule check.
Press Simulate and the firmware runs on the 3D board: LEDs light up, displays show their content, and you turn trimmers and press buttons with your mouse.
The assistant writes Arduino code for ESP32 (C3, S3, C6, classic) and AVR boards, compiles it and runs it in a simulator in your browser: LEDs, buttons, potentiometers, displays and serial monitor.
Real projects designed by chatting with the assistant, shown here in the 3D view with the firmware running.
ESP32-C3 board with its built-in 0.42" OLED, a DHT22 sensor and an alarm LED. In the simulation the tiny display shows the temperature.
Eight-LED scanner for Arduino Uno with a speed trimmer and a mode button, simulated in 3D before ordering the PCB.
PCBBrew is built for hobby and maker projects. It is not a tool for industrial or certified products.
⚠️ AI can make mistakes. Always review the circuit before building or powering it, take special care with mains voltage, and use proper protection when soldering (fumes, burns, reversed electrolytic capacitors). PCBBrew refuses designs meant to cause harm.
We are working hard on the last details and the beta is coming very soon. Invites go out in small batches so we can listen to every tester.
Yes, during the beta. Every tester gets free monthly credits; a project usually takes 15–50 credits. Paid plans will come later, with a discount for beta testers.
No to start: the assistant explains its choices and checks its own work. Some basic electronics knowledge helps to review the design, and the KiCad files are yours if you want to edit them.
ESP32 family (classic, C3, S3, C6), Arduino/AVR boards, common sensors, displays, relays and power modules, plus the official KiCad libraries for discrete parts. More microcontrollers are planned.
You do. You decide whether to publish a project in the public gallery; published projects are shared under an open-hardware licence (CERN-OHL-S or CC BY-SA) so others can learn from and remix them.
No, and on purpose: it is made for two-layer hobby boards. For very complex products (motherboards, TVs, high-speed digital) it proposes a smaller maker version instead, and it refuses devices meant to cause harm.
