Working perfectly, nice to have more memory in smaller then uno form factor
The product is a good replacement for more expensive Arduino Mega with same performance, but much more compact. Delivery was slow (41 days to Moscow, arrived the next day after the order protection ended). But it's not the seller's fault - most of the time it spent at Chinese customs. In Moscow it was delivered in 2 days, straight from the airport to my door - thank you, dear seller ) Tested it - everything works perfectly.
