It works, but...... it isn't coded. You have to ask seller where you can find the code(seller's Github), and upload the code by yourself. Seller's support is terrible. Don't expect any help from seller. If you are not good at Arduino, just don't buy this.
If you are stupid, buy from this seller. This seller is so disrespectful.
Missing cables from package, seller not even responded my message, NOT HAPPY!!!
