[GENERAL] Could I know how to identify if module is MBUS4, or 2, or 1, or even RS232?

Unfortunately, it is not possible to see what protocol is implemented by looking at the label. The only way to be sure is to read out the configuration using the UART pins and for instance our RCTools (https://radiocrafts.com/resources/supporting-software-and-software-tools/) . If you still have the original packaging and know which is from what package, it should be stated there.
