can i connect esp12f (esp8266 chip) to oled display ?
Maybe. Tell us which display.
I moved your topic to an appropriate forum category @jevonte .
In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
0.96 oled display ssd1306
I have done that.
Hi! Welcome to the Forum.
You don't seem to be in a rush, since you're coming back after 15 days of the original post. Happy 2025 by the way!
That was time enough for you to search for the answer on Google and take a look on How to get the best out of this Forum to see how to provide enough info for us to help you.
Anyway, in case it happens your module to be this one below:
then
GPIO02 = SDA
GPIO14 = SCL
(reference: https://arduino-projekte.info/produkt/esp-12f-esp8266-wifi-modul/)
I don't have the module, just the patience to ask Google. So, maybe @runaway_pancake can add something here after you tell us exactly what you have in your hands and what you're trying to do.
Actually im trying to make a deauther watch using esp 12f , ssd1306 oled display, tp4056 charging port, 3.7v lipo battery, AMS1117 voltage regulator, 10mf capacitor.
I tried connecting the AMS1117, 10mf capacitor to the out of the tp4056 charging port. From the out of AMS1117 i connected the VCC and GND of the oled display and esp12f separately and connected SCL to gpio5 and SDA to gpio 4 of esp12f, after switching the power on, the display didn't turn on.
Can share me the circuit diagram?
I might be wrong, but these are SDA/SCL ports for ESP12E. But you said you have an ESP12F. Have you tried what I said in post #6?
Gpio 4 & 5 are the sda and scl ports of esp 12f
I think im powering my display wrong
Well, if you are sure of it, ok, but not according to the reference I posted in #6...
There's no secret here. Common 0.96 OLED displays can work on 3.3V. So you just need to connect VCC of the OLED to the AMS Vout (or to 3V3 of ESP) and GND to AMS GND (or to ESP GND).
ESP GND should be also connected to the AMS GND.
Maybe it's time to draw your schematic or take pictures on how is everything connected.

I think #6 is correct but the deauther program asks to connect scl & sda to 4 and 5 respectively.
This how i've connected the circuit. I used an esp programmer, from it i connected it to two oleds in which one is completely connected to the programmer board (from 3v3 , gnd, scl(4),sda (5)) & to the other oled i only connected the gpios and powered it from ams1117. The first disply worked fine but the other doesn't
A second display was never mentioned before... 
You can have 2 or more I2C devices on the same line if each one of them has its own adress (which will not happen with 2 OLEDs with the exact same configuration).
As we do not have your actual configuration, nor code, nor schematics, this is my last answer on this topic.
No those two oled were meant for checking purposes . Original design consists only one design
