Yes, a pretty lame question but ...
I can google TTGO and find multiple vendors offering boards but I'm trying to figure out what TTGO actually stands for? where it came from? is it a pinout standard ... e.g. like the Arduino Feather? is it a trademark of some vendor?
The best I can figure so far is "It's a board with an ESP32 on it and then whatever other peripherals the board maker wanted to put on it". Design criteria seems to be based on 'well the P-N-P machine still has a roll of xxx mounted so why don't we create a TTGO xxx board" ... but I digress.
Lilygo seems to come up a lot boards but going to their site doesn't seem suggest they are trying to create a standard of any kind. But maybe I missed it.
There is no ttgo.com or ttgo.org or ttgo.net or ... that I can find.
So feel free to call me an idiot for not knowing what you think is intuitively obvious and\or easily discovered via Google, but after that some links to "the official definition of the TTGO standard, history, whatever" would be appreciated.
Thanks,
Arvid
