Cursor for Hardware

The AI code editor for hardware

AI editors made software faster to write. Codey Online does the same for electronics: describe a device and get the firmware, the wiring diagram and a board you can flash from your browser.

What is a "Cursor for Hardware"?

A Cursor for Hardware is an AI-first IDE for building electronics instead of pure software. You talk to an AI that understands microcontrollers, sensors and wiring, and it produces something you can actually build. Codey Online is exactly that - focused on the two platforms makers use most: Arduino and ESP32.

Code, wiring and flashing in one flow

Where a software AI stops at code, Codey goes further: it draws the connection diagram, checks voltages, compiles server-side and flashes your board over USB. It is the whole loop - idea, code, wiring, working device - without leaving the browser.

One AI for the whole build

From natural-language prompt to a device on your desk.

🛠️

Understands electronics

Pinouts, logic levels, sensors and libraries - the AI reasons about hardware, not just syntax.

🤖

Generates the wiring

Get a clear diagram of every connection so you can build the circuit with confidence.

⚡

Compiles and flashes

Server-side compile plus browser flashing means you go from prompt to running device in minutes.

Cursor for Hardware - FAQ

What hardware does Codey Online support?
Arduino (UNO, Nano, Mega) and ESP32 boards (WROOM, S3, C3). You can flash all of them from the browser over USB.
Is this a PCB design tool?
No. Codey focuses on firmware and breadboard-style wiring for microcontrollers, not PCB layout or manufacturing files.
How is it different from a generic AI chatbot?
Codey is built for hardware: it checks wiring and voltages, installs libraries, compiles the sketch and flashes your board - a chatbot only returns text.
Can I use it in my language?
Yes. The interface is available in 7 languages, including English, Dutch, German, French, Spanish, Italian and Polish.

Build your Arduino or ESP32 project with AI

Describe what you want to build. Codey Online writes the code, draws the wiring diagram, compiles it and flashes your board straight from the browser.
