=Changes for Arduino Due=

# Each Arduino Due I/O pin can provide a current of 3mA or 15mA (see [http://arduino.cc/en/Hacking/PinMappingSAM3X 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
