Fii - Fun Ideas Atmega328P-PU IC to Replace Burned Arduino Uno Boards (Uno Bootloader) (x3)

The product works as advertised. Plugged it in and was able to upload programs with no modifications whatsoever. Though, the chip says it is an Atmega328P-PU, it is a Atmega328P-U. I have no idea what the difference is, but thought I would mention it.

not one of the chips had the boot loader on it and none of the chips would accept a boot loader onto the chip. a package of duds is my guess

Product has good package and part function as it should.
