So I am making my own board using the atmega 328 but i have some problems
1. What is the difference between the atmega 328p and atmega328p-pu
2.I wanted to use the atmega 328 with dueminilove bootloader but I can only find atmega 328p-pu ones with uno. So would the circuit be the same and how would i program it would i use a ftdi cable or an atmega 8u2.
3.If i used a ftdi basic what do i do with the dtr(I know dtr is to auto reset the atmega but do i just connect that to reset on arduino)
and cts pins.
