I've use CP2102 based, CH340 based, and a PL2303HX based USB to TTL adapters on my Pine64 and other SBCs. All of them I have purchased from Aliexpress for less than $2 shipped. All work.
One thing to consider when using USB-TLL adapters is to make sure you are using the correct voltage adapter. Some are 5v some are 3.3v and some are jumper selectable. One of the UARTs on the Pine64 has protection on the RX if you happen to use a 5v USB to TTL adapter, I don't remember which one, I think it is the on on the EXP connector. Many other SBCs do not have this protection so just make sure you use the right TTL voltage otherwise you might damage your SBC.

Currently playing around with Arduinos, CHIPs, Orange Pis, PineA64s, Raspberry Pis, etc.
