Changes for Arduino Due
- Each Arduino Due I/O pin can provide a current of 3mA or 15mA (see pin mapping). Transistors are 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
