Which arduino to choose?

Arduino

I have never worked with programmable devices before (and with technology at the physical level in general - I played with electronic kits at most in childhood). But there is some experience in programming.
I want to learn how to assemble different devices based on arduino (for now, just for the sake of interest; in the future, perhaps, I will do something practical (I was especially interested in the ability to emulate HID).
I can’t choose myself, I can’t advise anyone. I would like to buy something average, without frills for a beginner, but still with the ability to do something more or less serious.Cost about $ 20-25. I also saw that there are many copies of other companies, somewhat cheaper than the originals - is it worth considering them at all?

For playing around in terms of compatibility with programs and libraries, as well as the number of ports, UNO is optimal. Leonardo is more modern, a little more ports and seems to be better for HID. Since the platform is open to make copies, no one forbids clones. By the way, they are better and more functional than the original Arduino - additional power connectors, for example, or built-in controllers of something. Absolutely cheap china with crooked soldering, of course, is not worth taking.

I did not notice much difference between the original mega and the Chinese one (except as soldering). In general, it all depends on the tasks that the controller will perform. Personally, I trudge from the beagleboard and write to node through an online ide. But the cost of this piece of iron is several orders of magnitude higher than arduino.
Offtopic: I have a lot of arduino-compatible hardware that I never used, I will gladly get rid of it inexpensively.

If you are interested in the implementation of a USB HID device, then it is probably better to take the Arduino Leonardo, because it has a full-fledged USB port, unlike the others, where HID can only be implemented in software, which will certainly affect the speed.
And just to "play around" I personally took a Chinese Nano clone, with a Chinese CH340, instead of FTDI. It's cool that it fits right into the breadboard, and you don't need to pull long wires to it, like the Uno.
As I debug the current craft, I plan to take another Pro Mini clone, which does not have a built-in USB-Serial converter at all, and costs about $ 2.

I advise you to take a simple scarf on STM32F103. The cost is about 400-500 rubles.
ARM architecture, unlike ...
In general, much better than ardurin on atmel. At least there will be some benefit, and not just play around and throw it away.
PS And there are penny STM32F042 with hardware USB ... Yes, there are a lot of them - for any whim!

Take the Chinese clone of Arduino Leonardo. It differs from UNO in hardware support for USB and is recognized as a USB HID device. It is inexpensive.

As a result, I bought a Chinese clone of Arduino Uno, now I'm playing with it. With a set of breadboard, USB cable, LEDs, resistors, wires of different lengths, all together it cost 550 rubles. So far everything seems to be working. For starters, what you need.

You can also buy the whole set here.

For a beginner, that's it. I bought there everything works!
