You can correct the standalone of atmega64A?

[loctogone_0928]

Hello everyone,
I have created a standalone with an atmega64A (with the Datasheets) and I would like to know if I have not made any errors.

• The purpose of it will be to communicate with a nextion.

Using a "capacitor array" as shown in the schematic is not ideal. The bypass caps should EACH be place "close" to the power pins, which means separate caps on at least two sides of the chip...

I have an ATmega128 "Wiring Revival" project published here: Revive "Wiring" ? | Hackaday.io
It works (with m128. I believe the ATmega64 is pin-compatible.)

Ok, like that then:
