I wonder if it is reasonable to replace atmega1280-16PU
of a bricked arduino mega board?
If yes, does soldering in there a bigger uC make sense? i.e. atmega2560
?
What microcontroller would fit there best?
I will not have problems with soldering. But a new mega1280 is half the cost of a new arduino.
I need this board for RepRap Mendel Prusa, so I think the 2560 version would be better...
Any suggestions?
Thanks, Martin.
EDIT:
We now know that the pinouts are the same. But the old version of arduino MEGA which i have has an FTDI chip for communication and the newer ones have an atmega8 or atmega16. The schematics also differ.
So there is a possibility that the new bootloader will not work in the old board. So I would have to use the old 1280
bootloader which is pointless.
It is not worth the time to investigate it further. I will simply stick to the ATmega1280
chip.
Thank you all for participation.
