Do any of you now exactly how to hook up the esp 32 ? For example for the esp8266 you need to put 3.3v to the 3.3 and EN pin and GDN to GDN and IO15. I keep reading that for the esp32 you only need to wire the 3.3v and GDN pin but i haven’t been able to make it work. This is for a new pcb project if you guys were wondering why i don’t just use a dev board.
thanks in advance !
This might help, has a wiring guide …

So i figured it out and will post my findings below for the next person who comes asking this question.
I used this diagram for the wiring and concluded that to power the ESP32 you need to give the 3.3v pin and EN pin 3.3V and connect the GDN pin to GDN. If you want to program a ESP32 chip like i do i recommend the following.https://nl.aliexpress.com/item/ESP32-test-board-small-batch-burn-fixture-for-Le-Xin-ESP-WROOM-32-module/32802723152.html?spm=a2g0s.9042311.0.0.6p3rFb
These babies are GREAT i have been using the esp8266 model for a couple of months and they are a great time saver. But if you want to go the CP2102 route you should follow the diagram above and when you are about to flash your code to the esp32 you need to press and hold the BOOT button. In my experience this is the only way i made it work.

Thank you very much for sharing this intel! Looks like a very good place to start. I’m too lazy to make PCB’s, so I just order dev boards, LOL.
