Scheme of hc-05

Hello,
I wish you well, I do not know if I am on the right topic,
i am working in a project with atmega328 au and hc-05 (master and slave) i am creating board, but i need the hc-05 scheme, if anyone can provide me.
thanks

Is the 328 powered by 3.3V or 5V? What, exact, HC05 module?

Read the forum guidelines for some advice on how to ask a question.

Hello, I apologize if I broke any rules

i have implemented a 3.3v voltage regulator, and i am thinking of implementing hc-05 only chip

Look at the schematics of the commonly available HC05 modules.

Why not just provide a header for the HC-05 to plug into on your PCB?
Why not just provide a pair of headers to plug a Nano into on your PCB?
Why reinvent the wheel when if you use the existing modules it is easy to replace (cheap) each module if you have problems.

Also using the HC-05 and Nano you get already tried and tested hardware.
Just a though, done it many times like this.
