The Arduino Mega 2560 is a very powerful EZB microcontroller. The high number of pins and hardware peripherals makes it a multitasking monster. With the high number of ports, you can use 8 ADC, 13 PWM, 21 Digital ports, and 24 Servos at the same time!

ADC Ports

ARC has the ability to select up to 8 ADC ports per EZB. The MEGA has 8 ADC capable ports mapped to the ARC ADC ports starting from ADC0 to ADC7...

(ARC Left, Arduino Right)
  ADC0 = A0,
  ADC1 = A1,
  ADC2 = A2,
  ADC3 = A3,
  ADC4 = A4,
  ADC5 = A5,
  ADC6 = A6,
  ADC7 = A7

PWM Ports

ARC has the ability to select up to 24 PWM ports per EZB. The MEGA has 13 PWM capable ports mapped to the ARC PWM ports starting from D0 to D12...

(ARC Left, Arduino Right)
  D0 = 2,
  D1 = 3,
  D2 = 4,
  D3 = 5,
  D4 = 6,
  D5 = 7,
  D6 = 8,
  D7 = 9,
  D8 = 10,
  D9 = 13,
  D10 = 44,
  D11 = 45,
  D12 = 46

Digital Ports

ARC has the ability to select up to 24 Digital ports per EZB. Digital ports also operate as bit-bang serial/uart (transmit only). The MEGA has 21 Digital capable ports mapped to the ARC Digital ports starting from D0 to D20...

(ARC Left, Arduino Right)
  D0 = 2,
  D1 = 3,
  D2 = 4,
  D3 = 5,
  D4 = 6,
  D5 = 7,
  D6 = 8,
  D7 = 9,
  D8 = 10,
  D9 = 11,
  D10 = 12,
  D11 = 13,
  D12 = 44,
  D13 = 45,
  D14 = 46,
  D15 = 62,
  D16 = 63,
  D17 = 64,
  D18 = 65,
  D19 = 66,
  D20 = 67

Servo Ports

ARC has the ability to select up to 24 Servo ports per EZB. The MEGA has 24 Servo capable ports mapped to the ARC Servo ports starting from D0 to D23...

(ARC Left, Arduino Right)
  D0 = 22,
  D1 = 23,
  D2 = 24,
  D3 = 25,
  D4 = 26,
  D5 = 27,
  D6 = 28,
  D7 = 29,
  D8 = 30,
  D9 = 31,
  D10 = 32,
  D11 = 33,
  D12 = 34,
  D13 = 35,
  D14 = 36,
  D15 = 37,
  D16 = 38,
  D17 = 39,
  D18 = 40,
  D19 = 41,
  D20 = 42,
  D21 = 43,
  D22 = 68,
  D23 = 69,

I/O Port Expansion Board

Because the Arduino is merely a bunch of pins, it is nice to have a break-out shield board that has I/O expansion. This allows easier connecting of servos and sensors to the Mega. The break-out shield we recommend is the KEYESTUDIO Mega Sensor Shield V1 for Arduino Mega R3 Board 2560.
