Where can I get an atmega328 microcontroller?

Question

Electronics

Hello everyone
, I asked myself such a question where to get the atmega328? Tobish, I know that it is already installed in every arduino board (by the way, I have it). However, I only need a microcontroller, that is, the chip itself. On alik I found only a batch of 20 pieces - this is too much. If you are wondering why, then I will say that I am doing a homemade product for which the size of the arduino nano or mini is too large.
PS Yes, I know that it needs to be programmed with a separate usb programmer
PPS, if you know what it can be replaced with, then say, I do not refuse specific advice.

Answer 1

here they sell by the piece ,
but here
I don’t consider the option in the DIP package much cheaper . it is commensurate with Arduino Nano or Micro.
You also need to understand that it is almost impossible to solder a microcircuit in a QFP package with a conventional soldering iron.

Answer 3

If there is a radio parts store in your city, then go there. Those who send by mail either have a minimum order quantity or a minimum amount, and it just costs money to deliver. The result may be more expensive than China. At our flea market, for example, a man sells parts on weekends. The same China with an extra charge, but by the piece and without a monthly wait.
I don't know about replacement. The microcontroller is selected based on its characteristics for a specific task from those series that you know how to use. So only you know what suits you. However, you will also look for any other MK in the shops. Why change something then?
You have already been written about the programmer. Since you already have an arduin, then consider that you already have a simple programmer too.

Answer 4

For example, in Amperk .

Without a file selection dialog, no way - this is the user's security policy on the part of the browser. The minimum file upload procedure is:

1. Click on the button, for example, "Upload file"
2. Selecting a file in the selection dialog
