4/23/2024 0 Comments Arduino mega vs due pinout![]() The Arduino has a large support community and an extensive set of support libraries and hardware add-on “ shields”, making it a great introductory platform for embedded electronics. The board contains everything needed to support the microcontroller simply connect it to a computer with a micro-USB cable or power it with a AC-to-DC adapter or battery to get started. We recommend you use something like our bidirectional logic level shifter to interface this board with 5V systems. Connecting higher voltages, like 5 V, directly to an I/O pin could damage the board. The maximum voltage that the I/O pins can tolerate is 3.3 V. Unlike many other Arduino boards, the Arduino Due board runs at 3.3 V. The Due is compliant with the Arduino 1.0 pinout it has SDA and SCL pins near the AREF pin and an IOREF pin, which can be used by shields to detect the microcontroller board voltage. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), a 84 MHz clock, a USB OTG capable connection, 2 DAC (digital to analog converters), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button. It is the first Arduino board based on a 32-bit ARM core microcontroller. The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. Please see the shield user’s guides for more details. The Arduino Due works with our motor shields, though the motor driver shield current sense outputs can exceed the Due’s 3.3 V I/O pin limit at high currents. ![]() As such, there could be incompatible Arduino shields and libraries. Note: There are differences between the Arduino Due and previous Arduino boards. ![]()
