Hello, does anyone has official arduino specification with all electronic schemes of arduino nano or uno. Or how to use atmega328p?
I am having a hard time understanding what you want. The reference designs for the Uno and the Nano are available on the net. The reference design docs include schematics.
Use atmega328p for what? Minimal mega328 board.
Google is a great way of finding stuff like this.
AFAIK for all official Arduino boards the schematics are published by Arduino. No need to second guess, Google and hope for the best, etc. Just go to the product page of the Arduino you want the schematic of and scroll down until you see 'schematic'.
E.g. Nano:
Product page is here: Arduino Nano — Arduino Official Store
Then scroll down until you see "Schematics", which are here: https://content.arduino.cc/assets/NanoV3.3_sch.pdf
For newer boards the schematics, pcb design etc. are also viewable in Altium 365 viewer. For older boards (such as Nano) pdf's are generally published.
Along with the .pdf schematic, the UNO and Nano documentation includes Eagle .brd (board layout) and .sch (schematic capture) files together in a .zip archive. Perhaps your schematic capture and board layout program(s) can import the Eagle files.
