ATmega328p
This is the microcontroller we’re using, ATmega328p. It’s a popular 8-bit AVR microcontroller which was used e.g. in Arduino Uno.
Make sure to order the ATMEGA328P-PU variant i.e. the one in 28-pin DIP package. The ATmega328p comes in a few different packages, and we need specifically the through-hole DIP 28 package, not a QFN or QFP package.
