 There is one additional caveat here: You can only change fuses that are compatible with what the bootloader you plan to use will let you do. Again there isn't a lot of documentation here, so if you've done everything right but things still don't work, this might be the reason. The solution to this is to compile a custom bootloader, which is well beyond the scope of this piece.

 This too is a pretty big topic, but the TL;DR is: hook up a programmer to your board, select the right board and programmer, then do a //Tools > Burn Bootloader//. This [[https://learn.sparkfun.com/tutorials/installing-an-arduino-bootloader/all|Sparkfun tutorial]] is a good reference if you need more hand-holding.

 Confirm that the extended fuse is still ''0xFE''.
-You can now connect the Pro Mini to a variable supply to see whether it works as expected below 2.7V. It may not work all the way down to 1.8V though, but because you're not using a bootloader, you won't run the risk of corrupting your program memory.
