Do someone recognizes this PCB and know the name, model, brand, etc?
Where did you take the photo ?
It looks like an ESP board is the controller under your black marker pen.
What are you hiding under those dark green strokes?
Where did you find the board and why does its exact nature matter?
It has network/phone cable connectors.
Is it an ADSL board?
Where did you get it?
If you've got an Android phone taka a picture of it and search with 'lens'.
Hi, @lolibeta
What have you redacted with the black marker?
(Are you serious or is this a thread that should be in "Bar Sport"?)
Controller IC, probably 3V3 powered by the looks of U1 possibly being a 1117 or some sort.
The controller IC of the ESP32 variety with WiFi.
Program and printer ports and a reset button.
A controller board of some sort.

A friend sent it to me and I'm trying to help him since he doesn't understand English. thank you for mentioning ESP board. Just google it. would you happen to know if it is composed of two separate part, one being the ESP board, and the other one is unknown. Or this is just one board that come as it is? appreciate any help, info, tip you can give us.

@TomGeorge hello

If you have more info, or more name of parts, anything that can help us, please let us know. thank you in advance.
Ask the friend what they are hiding.
Better: ask the friend where the board came from.
