ESPBoards Online ESP32 Tools

Explore our collection of powerful, browser-based tools tailored for ESP32, Arduino, and other microcontroller boards. Whether you're debugging, uploading code, designing graphics, or composing buzzer melodies, these web-based tools help streamline your development workflow—no installations or extra software required.

🔧 Development Tools

• 🖥️ Online Serial Monitor Tool – Monitor real-time logs, sensor data, and debugging output from your microcontroller via USB directly in your browser. Works just like the Arduino IDE's Serial Monitor, but no software install needed.
• 🚀 Online ESP32 Program Uploader Tool – Upload firmware or Arduino sketches to your ESP32 devices right from the browser. Skip the IDE and deploy code effortlessly with this guided uploader.

🎨 Display & Graphics Tools

• 🖼️ Monochrome Bitmap Tool – Create and preview 8×8, 16×16, or 32×32 pixel graphics for OLEDs like the SSD1306. Export data for use with the Adafruit GFX `drawBitmap()` function.

🎵 Audio Tools

• 🎶 Web Audio Grid Sequencer – Compose and preview buzzer melodies in a grid-based sequencer. Export `melody[]` and `noteDurations[]` arrays ready for ESP32 or Arduino using `ledcWriteTone()`. Also supports importing existing melody code for visual editing.
