===Summary=== | |||
This article is about finding the best ''TTL to Serial Adapter'' available on the market today. It is written in regards to the Linksys AC Series of routers. But the information can applied to [[wikipedia:Arduino|Arduino]], [[wikipedia:Raspberry_Pi|Raspberry Pi]], and other similar single board computers or routers. | |||

TTL is an acronym for [[wikipedia:Transistor–transistor_logic|Transistor-Transistor Logic]] (not [[wikipedia:Time_to_live|Time To Live]] which is related to [[wikipedia:Domain_Name_System|DNS]]). The definition of TTL by Wikipedia doesn't do a great job of explaining how TTL relates to [[wikipedia:Serial_communication|serial communication]] method that takes place over copper wires. And technically, when referring to a ''Serial Adapter'', the more accurate terms are [[wikipedia:RS-232|RS-232 or V.24]]. | TTL is an acronym for [[wikipedia:Transistor–transistor_logic|Transistor-Transistor Logic]] (not [[wikipedia:Time_to_live|Time To Live]] which is related to [[wikipedia:Domain_Name_System|DNS]]).

Try searching for something like ''best, ttl, serial, adapter''. All of the top results list a lot of ''TTL to Serial Adapters''. But none of them state why. And it's obvious a lot of them are written in an automated fashion, for the purposes of scoring high on a search engine's results. Not many of them care. For instance, this example: https://www.findthisbest.com/best-serial-adapters/converter. It's just a long list of products. No testing results, no comparisons, no methodology, just a bunch of aggregated information. Now compliments do need to be given to the author, Mike Davis, in term of SEO refinement and being listed as a top search result. But for substantive content, that article is like a candy bar. It might taste good, but in terms of nutrition (IE, equating nutrition to knowledge), it's useless. | |||
