Changes for Arduino Due
- Each Arduino Due I/O pin can provide a current of 3mA or 15mA (see pin mapping). Transistors may be needed for LEDs, speaker etc.
- The Arduino Due runs at 3.3V. Therefore, all signal lines also need to run at 3.3V:
Module 5V signal output-----10k---+---20k---GND

Arduino Due 3.3V signal input
Following modules and pins use 5V signal output:
Module Signal output Pre-amplifier LM386 OUT Motor driver MC33926 M1_FB, M2_FB Ultrasonic HC-SR04 Echo
Following modules already use 3.3V signal output (and use 3.3V compatible signal inputs):
Module Signal output WIFI ESP8266 TX Bluetooth HC-05 TX GPS GY-NEO6MV2 TX IMU GY-80 SDA RTC DS1307 SDA Current sensor INA169 OUT
Interrupt pins
The Due can generate an interrupt on any pin, the Mega 2560 only on the following pins:
6 PE4 OC3B INT4 Digital pin 02 PWM 7 PE5 OC3C INT5 Digital pin 03 PWM 19 PB0 SS PCINT0 Digital pin 53 SS (SPI Slave Select input or Pin Change Interrupt 0) 20 PB1 SCK PCINT1 Digital pin 52 SCK (SPI Bus Serial Clock or Pin Change Interrupt 1) 21 PB2 MOSI PCINT2 Digital pin 51 MOSI (SPI Bus Master Output/Slave Input or Pin Change Interrupt 2) 22 PB3 MISO PCINT3 Digital pin 50 MISO (SPI Bus Master Input/Slave Output or Pin Change Interrupt 3) 23 PB4 OC2A PCINT4 Digital pin 10 PWM 24 PB5 OC1A PCINT5 Digital pin 11 PWM 25 PB6 OC1B PCINT6 Digital pin 12 PWM 26 PB7 OC0A PCINT7 OC1C Digital pin 13 PWM 82 PK7 ADC15 PCINT23 Analog pin 15 83 PK6 ADC14 PCINT22 Analog pin 14 84 PK5 ADC13 PCINT21 Analog pin 13 85 PK4 ADC12 PCINT20 Analog pin 12 86 PK3 ADC11 PCINT19 Analog pin 11 87 PK2 ADC10 PCINT18 Analog pin 10 88 PK1 ADC9 PCINT17 Analog pin 09 89 PK0 ADC8 PCINT16 Analog pin 08
