The easiest way to code CircuitPython. No installation required. Perfect for Education and Hobbyists. Supports Chromebooks.

• Instant Setup: This IDE runs entirely in your browser. Just plug in your board and start coding.
• Powerful tools: Comes with a built-in Library Manager and Serial Plotter.
• Education Ready: Works flawlessly on school Chromebooks where installing software is blocked.

The first-ever visual debugger for CircuitPython is here! Step through your code, set breakpoints or conditional breakpoints, track variables, and rewind time to catch bugs before they happen.

Never worry about dependencies again! Just write your code, and the IDE will analyze your imports and install all required libraries with a single click. You can also search and browse the entire Adafruit and Community Bundle to discover available libraries.

Visualizing sensor data? You don't need external tools. Plots numeric data from the serial output in real-time. Perfect for STEM experiments.

Manage files on your microcontroller just like on your computer. Create, edit, and organize without leaving the browser.

Showcase your microcontroller to others during streaming, remote learning or collaboration. Share your camera feed directly through the IDE.

You only need 3 steps:

1. Plug your CircuitPython board into your computer via USB.
2. Open the CircuitPython Online IDE (https://circuitpy.dev) in browser.
3. Connect your microcontroller following the Navigation tab.

• Hardware: Supports all CircuitPython boards.
• OS: All desktop OSes including Chromebooks.
• Browsers: Google Chrome, or Chromium-based browsers such as Microsoft Edge, Opera.
