Product received. Bur the description and photo’s says it comes with library of examples. IT DOESN’T!!! I contacted the seller and he sends me PDF files with some code examples in Chinese. So you don’t get the example project files. Without the files the product is almost useless.
I have received the board, works ok. But nothing else. The sellers shows schematics, documentation, and a lot of sample code shown in the pictures. What I have received is the board only, no docs, no sample code. I have asked the seller and I have received pdf files with schematics and documentation (in Chinese, but that was expected...) But no sample source code at all, even though there are screenshots with a lot of files in the description of the item so I expected to receive it. I have asked the seller again about it but unfortunately I did not get any additional files. This is really disappointing.
