So I’ve always worked with the ATmega328p and I have put it on a breadboard and uploaded sketches and such that way.
I want to know if the ATmega2560 is generally the same deal? Obviously it doesn’t come in a DIP package, but how would I upload sketches to it if I were solder the 2560 onto a breakout or a circuit board? Is it the same with the TX and RX?
BONUS: I need help setting up a usb or serial connection or w/e, so if anybody has any resources on adding that ability to upload sketches from the usb to the microcontroller, that would be great!
