About GND Pins from i.stack.imgur.com It doesn't have the esp12 soldered onto the board. The arduino mega has in total one 3.3v pin and four 5v pins, which are able to provide a current up to 50 ma. On the arduino mega the spi pins are on different pins.
The mega is designed to be compatible with most shields designed for the diecimila or duemilanove.
However in the schemati i2c bus seems to be on pins 43 and 44. Arduino mega 2560 is an arduino board with atmega2560 microcontroller. Note that the distance between digital pins 7 and 8 is 160 mil (0.16), not an even multiple of the 100 mil spacing of the other pins. There are 54 input/output digital pins and 16 analog input/output (i/o) present on the mega board.
