      Great, also could you please mention esp32 SOC version, there are many different versions, that could be helpful.

        My application needs to use BLE option. So, I would like to get config for WROOM 32. If you feel it is less effecient please do send me ESP32's version suitable for my application.

          take a look at the ESP32 wroom data sheet page number 19, they provided a minimum circuit

            @salmanfaris thanks for the reply but this is not exactly what I am looking for I think this is the system on chip version of ESP 32 Wroom. There is no LNA circuit connection for antenna part. Please let me know if you find the the appropriate connections for the ESP 32 stand alone chip. To be simple, I want the circuit that we find when the metal part of SoC is removed.

              @kowshik1729 so you need the SoC minimum config, not the Module right?

                Yes, Exactly. I need PCB layout for something as shown below. The rip opened part.

                  @salmanfaris said in PCB Design for ESP32 Stand alone module:

                  take a look at the ESP32 wroom datasheet page number 19, they provided a minimum circuit

                  If you need the module schematic? the use this.

                    @salmanfaris Thank you so much. I am exactly looking for SoC minimum config, not the module. Shall ping the forum in case of any hassle.

                        The reason I wanna use online tools only is because, I have been using my company's lappy and I am restricted to install any other Softwares. So, online tools will be an easy way for me. by the way I have found another way too. EasyEDA provides an super easy solution for creating custom PCB shapes. It really came in handy for me.

                      • 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.😢
