The chip used in arduino 2560. Arduino mega tutorial pinout and schematics. Each pin can provide or receive a maximum of 40 ma and has an internal pull up resistor disconnected by default of 20 50 kohms.
Arduino mega 2560 pin diagram.
Do not finalize a design with this information. Digital pins 0 to 13 and the adjacent aref and gnd pins analog inputs 0 to 5 the power header and icsp header are all in equivalent locations. Arduino is a registered trademark. Arduino mega r3 has a voltage regulator for 5v and 3 3v supply for arduino controller and sensor supply.
