SMD board: arduino mega and TB6612FNG driver

Hi, everybody
I am currently working on a project with an arduino mega and a TB6612FNG driver with motors. Compactness is very important for my project. So I wanted to make a board. I can make a regular board using EasyEDA. But it is very difficult for me to make a professional SMD board.
For the SMD board, you need: arduino mega, TB6612FNG driver, the code will be downloaded via the USBasp programmer.

Here is the full outline of the Project:

I need to be able to order soldered components via jlcpcb. Now I want to know the price.

Image unreadable. Please try again.

JLCPCB gives you an immediate quote when you upload the project. Probably that would be the better place to ask.

No, I'm looking for a specialist who will develop an smd circuit board

would be a good option, then.

Do you have a working prototype built? I don't see any capazitors on your schematic. I assume the XL6009 refers to to the chinese boost module, not to the chip itself?

Sorry, I forgot to delete this dc-dc.
Here is a new picture of the circuit:

I have a prototype, but it's a wired connection

Where does the atmega get its power from?
EDIT: might it be that you want a "shield" to be made that's on top of the arduino mega?

From a 12V battery

More about the project:
I have a Barrier project. I am using an arduino mega pro microcontroller. To control the maxon 139885 engine, I use the TB6612FNG driver.

So, the prototype of the project works well for me. But for compactness, I want to make an SMD board.
To do this, I need to assemble the SMD: arduino mega and TB6612FNG. I will upload the code via ICSP.

As a beginner, I was looking for ready-made templates and schemes.
And I came across this scheme in EasyEDA. But I do not know if it is right or not.

After confirming the correctness, I can only integrate this scheme

Why don't you just get an arduino mega protyping shield and solder the 3 motor drivers onto it? There is ample space to do it. If not, what is your budget? I ask this, because only a monority of people posting to this category know what "profesional" translates to in terms of $$$ ... or €€€

With a budget in mind of < 50USD

Here you are: https://www.amazon.com/dp/B07DRG2LN2
... add two 0 to your budget, then you are in a "professional" range :slight_smile:
