Hello everyone,
I need a large amount of arduinos micros.
It would be great for it to have 20 pins or at least 15 (all usable as DI/O) and a atmega32u4 chip (Most Important).
I would need an unofficial arduino ( for budget reasons).
On banggood i found this one, but in the description of the product it says that there are 12 DI/O (but on the picture there are 12 + 5 Analog .
Can anyone help me on what choice to make ?
Thank you
Same thing for <1/2 the banggood price:

Or spend $0.13 more if you prefer eBay:

So the banggood one is good ?
Or i should buy the one from aliexpress ?
And on the aliexpress link, they say that there are also 12 DI/O
I really doubt there's any quality difference. Chinese stuff is always a bit of a gamble but you'll get a Chinese Pro Micro clone whether you buy on Banggood or Aliexpress or eBay.
As far as customer service goes, I have never bought from banggood so I can't make a comparison. I can say that, in the rare cases where something goes wrong with my purchase, I have had much better experiences with the sellers on eBay than Aliexpress. I think the eBay sellers are very concerned with their feedback score and the Aliexpress sellers don't give a crap.
An annoying thing about Aliexpress is that if you increase the quantity over 1 they try to charge you a bunch of money on shipping, even though the shipping is free on single quantities. So you need to check out over and over again to get the number that you want. I guess if you want to buy a lot you should contact the seller and ask for a price quote to see if you can get a discount.
I totally agree with Pert.
In addition with Aliexpress you just have about 15 days from the day the item is received to raise an issue. After that the transaction is closed and you cannot raise any disputes. So if you buy something and for some reason you are unable to use it right away, you might be in trouble.
Ebay give you more flexibility in this sense but that also has its own deadlines for complains.
Ok,
Well Thank you very much 
.
Have a great day
There's the Adafruit "ItsyBitsy 32u4" for $10.
