work as expected . well made on the board. only too expensive. useful only for development usage.
To get the package I had på pay 5,65 kr. as import VAT, to pay import VAT they charged me 75 kr as "declaration fee". So when i place one order, please put everything in one package, this sending lots of little packages makes everything very, very expensive.
quick delivery, all checked out ok. very clever chip.
nice board
Nice products
Absolutely predicable! Great value, all 5 units turned up in good condition. All work fine. This is the kind of sevice I have come to expect from Banggood. Thanks!
The boards I received were very clean and well marked. Can't find anything to fault here! Very satisfied...
