Need help with my IoT Project ESP8266 NodeMcu to ESP12-E | 27 March, 2021

Good evening, I am doing a project in which I want to measure air quality. I started the project with the ESP8266 NodeMcu board and three sensors, temperature (DHT22), VOC's (CCS811) and PM (PPD42).

I have it all assembled with a breadboard and the NodeMcu and it works fine.

The fact is that I want to pass it to PCB and I am a little lost. From what I've been reading, I have to use the same board but without NodeMcu, so I use ESP12-E.

I have tried to make a design on the web https://easyeda.com/, (I attach images). I copied the connections that I already have working and grouped all the GND connections in a single point.

The 3V3 pins I still have no idea how to do it, if anyone can give me a hand I would appreciate it.

Am I wrong or am I on the right track?

Thanks a lot! :)
