A short question about the circuit diagram of Ultimaker 2

Recommended Posts

Hi!

I went out and asked my technical colleague who asked our friends from R-D (it wasn't something I knew the answer to) and what I understand is that this jumper allows your Arduino to stay open when you plug in the USB and you can install new firmware.

Without it, the Arduino wouldn't reset and you wouldn't be able to upload new firmware.

Hopefully that is the answer you were looking for.

Have a good day!
