    Hello everyone! :) :)
    I'm new here and i need some help!
    Any help any help would be appreciated!
    Recently someone gave to me a pcb board with ATMEGA48 microcontroler and ask me if it is possible to be programmed from
    Arduino ISP, this board is old i think because dont have USB jack like arduino boards has, it use MXIB 95001 jack for communication (like router cable) and it has external power jack so i troubleshooting
    this is the board i been talking about
    Thanks in advance!

    Have a look at Optiboot (Google it) and see if that supports it.

    You cannot program the atmega the same way as an Arduino. The Arduino has a bootloader programmed into it that allows it to modify the program memory from data sent over the serial interface. In other words, once the bootloader is in the microcontroller, it isn't programmed with ISP anymore.

    I believe there are projects out there that allow you to use the SPI from a preprogrammed Arduino to program a bare AVR.

    Edit: Looks like the Arduino website shows you how.
