FAQ
Can the ATMEGA328P-AU microcontroller be replaced by the ATMEGA328PB-AU microcontroller, and vice versa?
Yes, such a swap is possible both ways.
Is such a swap time-consuming (e.g., requiring PCB modifications), or is it mostly software-related?
If swapping an older model (ATMEGA328P-AU) for the newer model (ATMEGA328PB-AU), only a minor change to the software is needed.
Can the decision to swap be based on a specific application, and can there be cases where it’s not possible?
The swap is usually possible in all cases. An exception is when the application and software make use of additional features of processor B. In such cases, replacing the newer product with the older one may not be possible.
