Atmega644 without a protected bootloader? Just program last uencrypted firmware using a programmer.

Hi Dimitry,

thanks you for your reply.

Yes i think so, but i am not sure. Look at the pictures of the inside of the MD please.

I dont know how to program is it possible to use this type of programming? https://docs.arduino.cc/built-in-exampl ... Breadboard

I have an arduino and breadboard here.

Otherwise, can i buy one programmed from yours?

Sorry Dimitry.

Thanks a lot

This is even older - Atmega32.
My last Atmega programmer broke so I'm not going to make any more Atmega644 with a protected bootloader.
You can buy Atmega644 and program it with the last unencrypted firmware - Atmega644 and Atmega32 are pin compatible.
You can use pretty much any Atmega programmer you can get to program Atmega644.
