Bad documentation

Testing the found module works fine, but programming and integration took a long time due to bad and missing documentation. No data sheet available. The voltage on the Rx/Tx pins is ambiguous; Do you need a logic level converter or not? Direct document upload is not available; You need to register on the remote sketch site and provide personal information (phone number). I had to scan the technical document after translating it from Chinese. The document was a bit helpful but lacked depth.

Pros

Always liked

Cons

Annoying
