PCB Design for ESP32 Stand alone module
-
Hello all,
I've been trying to make a PCB design for my ESP32 based application. I do not want to use a WROM-32 chip which is SoC instead I want to use my own ESP32 design. My application is to grab the values of accelerometer and gyroscope values from MPU6050 module using ESP32 controller and transmit these values using BLE. So, essentially my design must contain ESP32 chip, Antenna, MPU6050 IC and capacitors, resistors for this design.MPU6050 works on the I2C protocol. I am thinking of using an antenna from Antenova. I am attaching my schematic with this post. Please guide me in making my design.

Hi @kowshik1729,
Do you need an esp32 minimum config design? or ?
-
@salmanfaris Yes, exactly.
-
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.

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

If you need the module schematic? the use this.

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.
