Pros Cons
Easy to Use
They’re specifically designed to get anyone and everyone online.
Templates Can Be Restrictive
It can be difficult to put your own spin on the options available.
They Don’t Require any Coding Knowledge or Tech Skills
Website builders normally use a ‘drag-and-drop’ builder or a What You See Is What You Get (WYSIWYG) editor, so there’s no need for coding knowledge.
Can Get Expensive
Overall, website builders are the cheapest way to get online, but it depends on the plan you need. Some of the advanced ones are pricey. However, this shouldn’t be too much of an issue when you’re first starting out.
Good Customer Support
If you find yourself stuck, website builders come with a team of people ready to help you find a solution.
Less Overall Creative Freedom Than WordPress
It can be tricky to make your website stand out from the crowd when using a website builder. Unless you know code, you’re limited to the boundaries the builder sets.
Apps and Plugins Are Usually Included
You might have to pay for some of them, but generally, apps and plugins come included in the price of your plan.

Pros Cons
Takes the Pressure off of You
You don’t need to worry about anything – your designer will handle it all for you.
Limited Creative Control
You can tell your designer what you want, but they’ll have a different vision than you do, so you’ll have to give up some creative control.
Quality Website Design
The end product will boast a high-quality finish.
Expensive Fees
Hiring a professional is not a cheap way of getting your blog up and running.
Faster Than Doing It Yourself
If your website design is particularly complex, a web designer will be able to have it up and running faster than you could.
Harder to Fix if You Don’t Like It
If you don’t like your new design, it’s a lot harder to resolve the issue, because you might not have the technical knowledge to change it.

and if that wasn't enough you need to modify the " wire " library to be able to create two different objects (this may need to rewrite the whole library) starting here TwoWire Wire = TwoWire (); and becasue as you noticed none of this changes actually tells what pins to use for the busses, you also need to modify the " twi " library at least here. The default interface is located at pins 21 (SDA) and 22 (SCL). It can also be assigned to other pins. The second interface is not predefined regarding the pins, i.e. you have to set them before you can use them. The I2C interfaces of the ESP32 are located on pins 21 and 22 and / or on freely selectable pins.
