Any luck with Arduino UNO?

[starrpark]

I have an Arduino UNO R3. In the guide it says, that Leonardo boards don't work. What about UNO?

We need a mega32u4 controller (the original project is for it and there are no sources - we are not fantasizing, but repeating it). This MCU is present in the Arduino Leodardo, but there is such a pinout that it is impossible to use it just like that (without soldering) for this project, so much so that it is easier to take a bare controller, than to modify the Leonardo. But there is a ready-made solution - Teensy 2.0: this is what I suggested. Arduino Uno has a different controller and is not suitable for this task. Many other Arduinos and other debug boards are also not suitable - there is no point in listing them. Read the first proposal of my answer.
