This guide will cover updating the bootloader of the Pro Micro from the stock Caterina bootloader to the DFU bootloader.
Why would you update the bootloader?
Reasons:
Caterina bootloader only stays in bootloader mode for about 8 seconds when reset is triggered, while DFU stays in bootloader mode when reset, allowing for a better flashing experience
Don't have to figure out what COM/tty port the Pro Micro ends up on when trying to flash, which is one of the main problems with flashing on Windows
A Pro Micro you want to flash with DFU bootloader
An ISP flasher - a couple options here
A real one like USBasp
Another Pro Micro!
