PCB Design for ESP32 Stand alone module

@Sharmila GPIO0 must not be low all the time. It must be held low only for a moment. Because GPIO0 is a boot strap option for choosing between UART download and normal operation. Please refer to the datasheet and search boot strap. And also can you please post a snap of your newly designed board please?

@kowshik1729 thank you for the hint ! i will check it . schematic picture of my board is given below

@kowshik1729 sorry, gpio 0 is low only till it is programmed. after that this will disconnected.
-
@Sharmila Reviewed your schematics. Have the following doubts
- Is this a USB receptacle?
- Didn't find any option where you can pull the GPIO0 low and bring it back to normal state. Did you have a jumper connection or button between GPIO0 and GND?
-
- no.
- we are using jumper for gpio 0th pin. please refer the below image.

Hi all,
I recently came across this post where they have shown photos printed on PCB in high resolution. I would like to know how to add this kind of photos to the silkscreen layers of the PCB in Eagle/Altium.
Adding such kind of photos will be attractive for beginners and also can be used for educational purposes too.
Please let me know in case anybody knows. -
@kowshik1729 I think that might not get since the platform is not opensource! but they provided everything you need to develop a system with that.

@kowshik1729 Carrier board schematics for SoMs will be always available as they need to be modified as per customer application, however SoM design files are hard to get unless the H/W design is truly open-source.

@salmanfaris Actually the schematics files you've mentioned are the same files which I've got from them. They are carrier board design files.:cry:
