Schematik

Schematik calls itself the Cursor for hardware. Describe a gadget in plain English — a weather station, a tiny game console, a plant monitor — and it gives you the complete starter package: firmware code, a wiring diagram, a parts list and step-by-step assembly instructions, ready to flash to your board.

It works with Arduino Uno, ESP32 and Raspberry Pi Pico, in the browser or a desktop app, and you can flash supported boards directly from the browser. A built-in Preview runs your firmware on a simulated board in 3D, so you can check that a project works before wiring anything up — the step that usually costs beginners the most time.

It is aimed squarely at learning and prototyping: makers, students and software people building their first gadget without starting from datasheets. It is not a tool for professional hardware engineers designing production boards.

Pros

• Turns a plain-English idea into code, a wiring diagram, a parts list and assembly steps.
• Works with Arduino Uno, ESP32 and Raspberry Pi Pico, in the browser or a desktop app.
• Preview simulates your firmware on a virtual board before you wire anything up.

Watch out for

• No published pricing — the site lists no paid plans, so costs for heavier use are unclear.
• Generated wiring still needs a careful check before powering anything up.
• Aimed at learning and prototyping, not production hardware design.

Best for

Makers, students and software people who want to build a gadget without starting from datasheets. Who should skip it: professional hardware engineers designing production boards.

Pricing

Schematik publishes no pricing on its site — there is no pricing page, and the only statement available is that it is free to start building in the browser, with sign-in required to save and deploy projects. If you need to know what heavier use costs, check the official site or contact the team directly before committing to a project.

Example

A student types “build a weather station that shows temperature and humidity on a small display” and Schematik returns the firmware, a wiring diagram for the sensor and display, and a parts list with the exact components. After checking the wiring in Preview, they assemble the parts on a breadboard and flash the board from the browser.

FAQs

What boards does Schematik support? Arduino Uno, ESP32 and Raspberry Pi Pico — with browser Preview for simulated runs on each.

What do I get for a project? Code, a wiring diagram, a parts list and step-by-step assembly instructions, ready to flash to your board.

Do I need to install anything? No — it works in the browser, with a desktop app also available, and supported boards can be flashed directly from the browser.

Is it for production hardware? No. It is aimed at learning and prototyping rather than production board design.
