Arduino Uploader for VSCode

Brings the Arduino IDE 1.8 toolbar experience to VSCode — compile, upload, and monitor without leaving your editor.

Features

• Compile — Build your sketch with arduino-cli
• Upload — Compile and flash to your board
• Upload Last Build — Flash the cached binary without recompiling (fast!)
• Serial Monitor — Pseudoterminal-based monitor with auto-reconnect after upload
• Upload from History — Pick from the last 10 builds and flash
• Board Options — Configure Flash Mode, Partition Scheme, and other board-specific settings
• Board Manager URLs — Manage additional board manager URLs

Requirements

• arduino-cli 1.x (auto-downloaded on first launch if not found in PATH)
• VSCode 1.85 or later
• Windows only (win32-x64)

Keyboard Shortcuts

Shortcuts are active when a .ino file is open in the editor.

Usage

1. Open a .ino sketch file
2. Select your board and port from the sidebar
3. Press Ctrl+R to compile, Ctrl+U to upload

Notes

• This extension is a personal project and currently in preview
• Only Windows (win32-x64) is supported
• All compilation and upload logic is delegated to arduino-cli
