Arduino UNO board with an ATmega2560 controller

hello everyone,

i have several homemade printed circuits accepts arduino uno controller running out of both static ram , progmem memory (my programs highly optimized already).

all problems solved using arduino mega atmega2560 chip. bigger board  size problem , have redesign printed circuits.

do know if manufacturing arduino mega on board has size , pin of arduino uno ? not need i/o pin of arduino mega, need additional memory sketches ...

many thanks, potential suggestions...

regarda, albpace.

how extra? atmega1284 has 16k sram (twice of mega) , 128k sram (4x of uno).
i offer little bigger (longer) uno sized board:
