Hey hello friends welcome to another post, In this article, I am going to introduce my newly design fully SMT components used 2 channel remotely and manually controlled home-Automation PCB.

I have also made 8 channel SMT homeautomation PCB,4 channel smt homeautomation pcb.

and also TMT Components used home-automation PCB.

This home-autoamtion 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 Onboard Led’s which you could use according to your need like testing your code or 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.

To design the circuit and PCB, we used EasyEDA which is a browser based software to design PCBs.

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.

Ordering the PCBs at jlcpcb.

This project is sponsored by jlcpcb. JLCPCB is a full feature Printed Circuit Board manufacturing service.

Turn your DIY breadboard circuits into professional PCBs– get 10 boards for approximately $5 + shipping (which will vary depending on your country).

Once you have your Gerber files, you can order the PCB. Follow the next steps.

1. Download the Gerber files –click here to download the .zip file.

2. Go to jlcpcb website and Click on Quote Now button.

3.Upload the gerber file you downloaded in the last step. Upload file or you can also drag and drop the gerber files.

After uploading the zip file, you’ll see a success message at the bottom if   the file is successfully uploaded. You can review the PCB in the Gerber viewer to make sure everything is good.

jlcpcb can grab all the PCB details and automatically fills them for you.

To place the order, click on “SAVE TO CART” button.

Now select the shipping method , the one you prefer and has cost efficient.

I have received the PCB at my place with in a week, 

PCBs are well wrapped in  bubble wrap. and not just that but also the some foam inside and some more layers of  wraps,

Damaging during shipping is almost impossible.

All the components are well soldered and they are the correct components, and also the solder is well placed as you can see resistor, transistor they put just little bit of solder and the connection is great and also on the esp32 chip  each pin is well soldered and tracks are also perfect and...
