If I power the TX module with 12V and send data to it from a PIC at 5V, do I need to worry about isolation from the PIC data/USART pin? The walkthrough seems to sugest that it's fine, and the datasheet doesn't seem to say otherwise. I just wanted to check before plugging it in a possibly burning out a PIC.
