The article is being published in collaboration with JLCPCB. It is one of the most experienced PCBmanufacturers with more than a decade in the field of PCB prototype and fabrication, they are committed to meeting the needs of thier customers from different industries in terms of quality, delivery, cost-effectiveness and any other demanding requests.
Hey hello friends welcome to another post, In this article, I am going to introduce my newly design fully SMT components used 4 channel remotely and manually controlled homeAutomation PCB.
This homeautoamtion PCB is very small in size and compact which can easily fits in your electrical switch boards.
This PCB has inbuilt OTA button, that is, you can update the code wirelessly over the air.
And there is two Onbaord Led’s which you could use according to your need like testing your codeor something else.
In my case I have used as WIFI indicator that is if WIFI connection is available then both the Led’s will glow else only single Led will glow.
By using this PCB, I will make a small homeautomation system that is internet and manual controlled homeautoamtion system using blynk iot plateform.
In this home-automation system we can control our home-appliances by using blynk smartphone application from anywhere in this world
Apart from this we can also control our home-appliances through manual switches that we generally use in our homes and we can also monitor the real-time status in the blynk smartphone application.
This PCB is compatible for all the smart speakers available in the market like Amazons Alexa , google home and Apples SIRI.
Designing the PCB.
Designing the circuit works like in any other circuit software tool, you place some components and you wire them together.
Then, you assign each component to a footprint.
Having the parts assigned, place each component. When you’re happy with the layout, make all the connections and route your PCB.
Save your project and export the Gerber files.

Let's Make it...!
Now grab all the components whose list is mention below, and soldered on the PCB.
After soldiering rest of components PCB look like this neat, clean and well arranged.
Blynk mobile application is available for both IOS as well as Android users.
Scan the above QR Code with your phone and you will get a full copy of this project.
To flash the code into ESP32 chip, I will use ESP32 development board.
