PCB Design for ESP32 Stand alone module
kowshik1729 last edited by salmanfaris
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.
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.
@kowshik1729 so you need the SoC minimum config, not the Module right?
Page No. 18
Yes, Exactly. I need PCB layout for something as shown below. The rip opened part.

If you need the module schematic? the use this.
Very much informative!!!!
If you are using raspberry pi as one of your main computers and have separate monitor, keyboard and mouse, then you might be tired of copy and pasting terminal commands and codes while doing projects with raspberry pi, because running chromium-browser and reading tutorial will pi slower and using a sperate keyboard and mouse use our workbench space too.
recently I read a blog Share your keyboard and mouse between computers with Barrier by Gordon Hollingworth which is cool.
In that blog, he mentioned a software called barrier, it's a software that will allow you to use a single keyboard and mouse to control multiple computers by physically turning a dial on the box to switch the machine you're controlling at any given moment. The barrier does this in software, allowing you to tell it which machine to control by moving your mouse to the edge of the screen, or by using a keypress to switch focus to a different system.
Follow these to share your computer keyboard and mouse with the raspberry pi
First, we need setup raspberry pi
Step 1: Download and Install Raspberry Pi OS on SD Card
Step 2: Connect raspberry pi to the wi-fi network
Step 3: Install barrier, for that open your terminal (Ctrl + T) and paste or enter the followingsudo apt install barrier
Then click enter.
Step 4: Setup barrier, Open barrier by typing barrier on the terminal, if you successfully installed the barrier you can see like this.
Select option Client (Use another computer's mouse and keyboard) and Select Auto config option too, also note the Screen name, which we need for the server.
That's all next we need to set up the desktop/laptop computer.
Step 5: Download and Install barrier on desktop or laptop computer (The Server), download link
Step 6: Set up the barrier by selecting Server and position your monitor on barrier software.
To Position, the screen clicks the configure server.
Here, to drag and drop the monitor icon to the desired position you need on the grid.
double click the screen and set the screen name, you can obtain the screen name from the raspberry pi barrier client. (See Step 4)
after setup, it should be like this. Then click OK
in the following screen, click Apply and Just wait few seconds then try to move the mouse to the corner. Yes, It should work.
@rafitc99 Looks cool, Thanks for sharing.
