Greetings! He began to actively study microcontrollers of the AVR family. It's time to get ready to practice. In this regard, the question arose, what to choose for practice? With a soldering iron, I’m still on “you”, and therefore I would like to get a ready-made board with an installed microcontroller and peripherals (LEDs, seven-segment indicators, LCD display, etc.) for a start. How smart is it to buy a ready-made plan? And, of course, which and on the basis of which controller (ATMega16, ATMega128) should I choose and where is it better to buy (order)? On eBay, the choice is not very large, but there are interesting-looking specimens:

Start by searching for Arduino and Freeduino keywords. They can be ordered ready-made (i.e. you will get a ready-made piece of hardware, it remains to code the firmware and flash it into the MK, there are a lot of projects and examples)

Make your own debug board. It is not difficult, but immediately many things will become clear and you will feel that you did it.
There is a very good blog easyelectronics.ru/ - there you will find how to make the first flasher, a flasher for it, you will find the control of seven-segment indicators.
As for the controller, the classic mega8, you can even make usb gadgets on it.

If this is a hobby for you, look towards Arduino and its analogues. For starters, that's it.
If you decide to professionally develop electronics, choose debug boards with the peripherals you need ...
Well, where to buy - decide for yourself. There are many factors - both cost and availability.
For example, for Muscovites and St. Petersburg - arduins and analogues can be found in stock stores (Chip and Dip, Linux Center). But it will be more expensive than online.
It will be cheaper via the Internet, but delivery time plays here. You can buy the original Arduino through Ebay or other Western sites. It is important to remember about delivery here, unfortunately, this is not the fastest option.
Another option is Russian analogues, there are not very many of them, but there is a choice. Here is the best offer for cost and delivery. Manufacturers freeduino.ru robocraft.ru jt5.ru
There are also stores - ampere and others, use the search.

inside the avr already has everything you need. any peripherals, interfaces, etc. Avr will work without any strapping at all. outputs are strong enough. just to try, there is absolutely no point in taking a ready-made board, everything can be done on the edge of the table, knowing which side to take the soldering iron from and no more.

Did you both just want to advertise the site? “With a soldering iron, I’m still on “You”, and therefore I would like to get a ready-made board with a microcontroller installed for a start.”
Soldering a debug board and declaring “there is absolutely no point in taking a ready-made board, everything can be done on the edge of the table” otherwise it makes no sense.
PS and AVR won't work just without anything, first you need power on the right legs, and it's also a good idea to make sure that the internal clock generator is turned on.
Just to try programming arduino-based boards and they will do just fine
