    i bought atmega 8L by mistake instead of atmega8.
    Is there a way out to construct the ubasp mentioned above eith atmega 8L? (since they cannot be clocked to 16MHz)

    Hello Mr binu

    can i use atmega8L instead of atmega8 ? because atmega8 frequency is upto 16mhz but L have max 8mhz? so can i use this circuit with atmega8L with lower crystal value?
