first of all thanks for your great dev support around ATmega328pb.
Is it possible to run the A-star (or any other board with the same MCU) at 8MHz using its internal oscillator via Arduino-IDE? I am asking since the document says that the accuracy improved compared to the Atmega328p https://www.pololu.com/file/0J1464/Atmel-42559-Differences-between-ATmega328P-and-ATmega328PB_ApplicationNote_AT15007.pdf
Which bootloader/fuse settings would need to be taken?
Thank you in advance.
