@taraberg Since you will need to download various software and hardware files for using Python with CoDrone, you will need a compatible Windows or MacOS device. As for the browser-based Arduino workaround, I am not aware that it is still supported. I believe they changed their model to a paid subscription. You would also need to upload our files for our board as well should you go that route. The easiest way to use CoDrone with Chromebooks would be with Blockly.
