-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, the chances of corrupting program memory are very low.+You can now connect the Pro Mini to a variable supply to see whether it works as expected below 2.7V.
