Seems like another round of missing/no stock ATMEGA328PB TQFP devices (which are NOT the same feature-wise as ATMEGA328P)
I saw something about these coming in from Thailand.
Why doesn't the 48PB/88PB/168PB have the same feature set as the 328PB (like 5 timers, 10PWMs, 2 uarts, etc)
The regular 48/88/168/328 series are all duplicates, except for their memory sizes.
