Despite my experience with UNO and MEGA, I am only starting to develop projects with these 32U4 based arduinos. one thing I found out was that they brick a lot. Say I do a real time clock project code and the wire.begin() is stuck, maybe bad backup battery, then I couldnt use the board until I reflashed bootloader. Is this normal?
More serious question: if sketch is stuck, will arduino ide be able to reset the mcu at all? After all, there is just one chip. If it is stuck, its usb serial is stuck, too, right?
