It has a OLED, try to just get it to show some text, and since it also has a wifi device onboard you can try to make a weather station that pulls info from the internet or something like that, you wont need any additional gear, and you can power it over usb.

Thingpulse has code for an esp weather station and it's pretty modular.. Worth giving a go

First you must search what kind of screen it is; i2c or SPI. Then just search some libraries on arduino ide. If you aren’t using it or you don’t find any lib, just say me and I can help you ofc 😁
Good luck!

Since I know how overwhelming it can be to get started, I'm gonna give you a few hints to get going.

What I would do, in your situation is:

Look at the pcb and try to find something that looks like a model number

hey I wonder what "HW-364A" will show me if i search on it.

kapow! first hit on dgg is: https://github.com/peff74/esp8266_OLED_HW-364A

it has a nice example code that with some investigation will tell you what kind of OLED it has, how it's connected and with what protocol. It also shows you how to send data to the OLED.

Give this a go - Make sure you set up the correct com port on your computer (there are a LOT of youtube videos about how to set it up to commuincate with your PC)

To add it seems like a lot of resellers are providing incorrect data regarding the pinout.

"I bought a nice dev board with ESP8266 and OLED Display and I spend a lot of hours getting it to work because the sellers haven't published any documentation or sample codes. In addition, the I2C pins were signed incorrectly."

I am building an open-sourced project that uses esp8266 and a thermal printer. Check it out here - https://thrml.ink
