Dear ESP32 Members,
Does anyone know the schematic for this Dev board ?
https://www.aliexpress.com/item/Esp32-e ... 0.0.XFeuL2
And where can I find the original flash code ?
Any examples for it ?
Thanks
A schematic for this dev board ?

Re: A schematic for this dev board ?
This dev board uses the standard Wroom32 module from espressif.
The code that is currently loaded into the Chip is the standdard hello world application in the espressif ESP-IDF on githib.
You should be able to load and program all the standard examples to this board.

Re: A schematic for this dev board ?
You can find the pinout of the Espressif module here:
The schematic of the boards varies with the vendor of the boards.
The best way is to search google images.

Hi !
Try this: https://www.hackster.io/johnnyfrx/esp32 ... ted-07ac5d
Not the schematics but definitely a good starting point.
