30 March 2014 Question by: Keith | Product code: 73-4283
Q. What is the difference (apart from price) between the Atmega 328-PU and the Atmega 328P-PU?
A. Hi Keith. Thank you for your question. The main difference between the "P" version and the non "P" version is that the "P" version has lower power consumption.

Q. The technical specifications mention an atmega 328P-PU, the device used in an Arduino UNO. Do you sell them? (I can't seem to find it in the list of products in this range). I want to buy the raw microcontroler (Not on an Arduino and without the bootloader)
A. Thanks for your enquiry Daniel. I believe the product you are looking for is order code: 73-4283 .
