There are pin mappings to atmega8 and atmega 168/328 as well. It has 54 digital input/output pins (of which 14 can be used as pwm the mega 2560 also supports twi and spi communication. The spi pins are also broken out on the icsp header, which is physically compatible with the uno, duemilanove and.
Arduino mega 2560 pin diagram.
There are 54 digital i/o pins and 16 analog pins incorporated on the board that make this device unique and stand out from others. The arduino mega 2560 is a microcontroller board based on the atmega2560 (datasheet). The spi pins are also broken out on the icsp header, which is physically compatible with the mega2560 has 16 analog inputs, each of which provide 10 bits of resolution (i.e. Hi, i am trying to use mega with softwate spi sdfatsoftspi.
