I decided to put another one together, but I'm asking for help before I brick it. I thought I could just load the optiboot bootloader for the 328 that comes with the Arduino IDE. Is that the correct option?
I have a 16MHz crystal attached. So that would be fine. I guess at this point it might be easier to just ditch Atmel Studio and load the bootloader from my Uno set up an ISP and breadboard my clock.
I'm so confused as to what to use for low, high and extended.
