RV Circuit Studio IDE with plotter and data analysis
Visual debugger with breakpoints and watch expressions
Debugger

Visual debugging, not print() debugging

Set watch expressions, add conditional breakpoints, and step through your code line by line. The executing line highlights in the editor while watch values update live in the debug panel. Run, Step, Restart, Stop. See exactly what your variables hold at every point.

Dual-channel plotter with recorded data analysis
Plotter & Datalogger

Visualize, record, and analyze

Plot sensor data in real time from any print format. Hit Record to capture a session, automatically saved as CSV. Open recorded data in the Analysis View to zoom, pan, compare channels, and view per-channel statistics. Import previous recordings to overlay and compare runs side by side.

Code snippets with GPIO Quick Setup examples
Snippets

Complete examples, one click away

Double-click any snippet to open it as a complete working sample in a new tab. Categories include GPIO, debounce, state machines, ADC/DAC, PWM, DSP filters, serial protocols, and more. Learn by running real code, not by reading docs.

Auto-install missing libraries from imports
Library Manager

Auto-install from your imports

Click Auto Install and the IDE scans your imports, finds the matching libraries in the Adafruit Bundle, and installs them directly onto your board with one click. Or browse and search the full Adafruit and Community bundles manually. No downloading zip files, no dragging folders.

Everything you need. Nothing you don't.

Built for CircuitPython developers who want a real IDE without the bloat.
