I wanted to do my own. I know PCB design . If circuit is know i can build it. These product are good .takes long time to deliver

Very confusing answer.

You say you like the products but they take too long to deliver. You say you know how to design and built a PCB.

Why not just use the schematics from the Pololu products and repurpose them to your use?

What are we missing?
