| Aug 12, 2021 at 21:31 | comment | added | ElectronSurf | @chrisl I know how optocouplers works, I just don't know how to implant it as serial communicator. | |
| Aug 12, 2021 at 20:39 | comment | added | chrisl | I didn't want to suggest, that you are lazy. I would suggest to read a generic tutorial about optocouplers, not directly involved with UART/Serial. They are pretty simple components, so the general principle is also how they are used for Serial. When you understand how they work and how they are wired you should be able to build them into your Serial path. I guess you searched for tutorials directly with the Serial lines, but there are many tutorials when searching only for optocoupler tutorials. | |

| Aug 12, 2021 at 20:14 | comment | added | chrisl | So you still want communication via a wire, but just with isolated grounds? Then yes, the optocoupler is the correct way, one for each UART/Serial line. You can find tutorials on how to use an optocoupler on the web. Do you have any specific questions about it? | |
