    Hello, and Welcome, please tell us what program/s opens uf2 files, or specifically, the program you plan to use.

    I have found references to a specific microcontroller firmware type: github.com/Microsoft/uf2 and learn.adafruit.com/… Is this what you mean?

The .UF2 file format appears to be a fairly compact, binary format for reliably transferring data to "microcontrollers" (i.e. small embedded systems such as the EV3 controller), and is the format used by the Microsoft MakeCode application, recommended as part of the First LEGO League.

The .ev3 file is actually a zip file containing a number of additional files, of which the .ev3p is an XML file representing the program itself.

At this time there isn't an official way to convert .ev3 programs to the .uf2 format, not least because things like custom blocks will need to be re-written in JavaScript, and certain other features may not be currently supported (i.e. data logging beyond console logging, 3rd party sensors, etc.).

    The new Scratch-based software compiles to .rbf like the old desktop software, not .uf2.
