So I have a few boards that I can salvage a few parts off of them, the one I would like to work with is the esp8266 chip. I would like to remove the WiFi chip and use it to make my Arduino project WiFi. I have found several places on the web that shows how to use a WiFi chip on an Arduino but am unable to understand trhe pinouts that are being used.Example CH_PD enable ,there is no such pin on the wemos d1. All I want to attempt is to remove the WiFi chip and intergrate it to a UNO or a Nano, any help would be appriciated.Thanks

You have answered your own question, A mounted esp WiFi chip will have few OR Many I/O pins and functions bought out to terminals. So The Wemos D1 brings to the “Surface” 16 pins where in fact the Bare esp8266 has 22 physical connections / 34 function pins. There are plenty of UNO ESP8266 shield projects which explain interconnections. Rui Santos of RNT is an excellent source of information and goes into great detail with his project work and follow-ups, I would strongly recommend a hop to his website as a starter on your journey.

So thank you Steve for responding to my question, either I didn’t ask the question properly or you didn’t understand what I was asking. I have some of the chips that I have salvaged from the Wemos D1 mini ,I would like to know if anyone can tell me how I could possibly incorporate them into a Nano development board.
My goal will be to get some use out of them rather than throw them out once removed ,I know that I could just as easily purchase them as they are pretty inexpensive .I am currently subscribed to RNT and I do enjoy their course , The picture you posted in your message is what I have seen all over the internet ,that given does not help me with physical connections or answering my question. I have to assume if this chip is on a board ,once removed it should still be viable and useful to some degree, also I am currently moving my circuit from breadboard to a circuit board , again thanks for your response.

Hi Larry.
To connect the chip to an Arduino UNO, you can use the chip serial pins and then communicate with the chip via Serial communication.
I think the connections are similar as if you were using an ESP-01. So, please search for the corresponding pins on the chip and wire it as shown in this tutorial: http://www.teomaragakis.com/hardware/electronics/how-to-connect-an-esp8266-to-an-arduino-uno/.
I hope this helps.
Regards,
Sara
