Arduino due12/29/2023 ![]() These pins are used to read the value coming from the analog sensor connected to the board.PWM output value varies between 0 (0 volts) and 255 (5 volts).Īnalog Input pins: Arduino Due Analog Input pins To generate the PWM output, syntax “ analogwrite(PWM Pin, PWM value)” is used.Each PWM pin provides 8-bit PWM output.The 12 pins from the set of digital pins are PWM (Pulse Width Modulation) pins which are numbered as 2,3,4,5,6,8,9,10,11,12, and 13.PWM pins on board: Arduino Due PWM enabled pins This type of input is usually known as digital type (or binary) and these states are referred to as HIGH which is 1 or LOW which is 0. The Arduino Due digital pins like every other Arduino board can read one of the two states: when the electric signal is present and when it is absent.The Arduino Due board comes with 52 digital I/O pins that can be used as an input or output.GND: Five ground pins are available on the Arduino Due board. The power source of the 5V pin for the Arduino Due board is a USB connector and the Vin. Note: Above 12 volts, the board might overheat whereas voltage below 7 volts might not be sufficient to power the Arduino Due board.ģv3: The 3.3V pin generates an output voltage of 3.3v.ĥv: The 5V pin generates regulated 5v output for the externally connected components. The Arduino Due board can be powered by an adapter that ranges between 5-20 volts but the manufacturer recommends keeping it between 7-12 volts. An adapter is plugged into the power jack. Power jack: A barrel jack or 7-12V DC Power Jack can be used to power the Arduino board. When a certain voltage is given via the USB port to power the board, this voltage is reflected at the Vin pin. Vin: This is the input voltage pin, which can be used to power up the Arduino board. We can connect external keyboards, mouse, and smartphones to this port. Native port: This port is directly connected to the Atmel SAM3X8E microchip and is used to emulate the USB devices.This port is recommended to use for programming purposes. Programming port: This port is connected to a powerful 8-bit microcontroller Atmel 16U2, which acts as a USB to serial converter.USB port: Arduino Due has two micro-USB ports that can be used to power up as well as program the board. Power pins and ports on Arduino Due board: And out of these 12 are PWM enabled, with 12 analog input pins. Arduino Due Pinout A (side pins) Arduino Due Pinout B (bottom pins)Īs shown in the Arduino Due pinout image, the board consists of more than 90 pins in total, 54 of which are digital I/O pins. Pinout image A describes the side pins of the board whereas Pinout image B describes the bottom pins of the board. RESET button: The board comes with a RESET button that can be used to reset the board and begin the execution of the program from the beginning.ĮRASE button: The Arduino Due comes with an ERASE button that is used to erase the flash memory of SAM3X.Īre you a beginner? Not sure which book to read? Don't worry! Read this article on Best Arduino Books for beginnersĪrduino Due pinout is shown in two separate images. TX and RX LED: On the board, there are two more LEDs connected to the UART pin. Power LED: The board comes with a power Led that lit up as soon as the board is connected to a computer. This Led can be controlled by switching the pin HIGH or LOW Inbuilt LED (13): An Inbuilt LED is also present on the board that is connected to pin no 13. A DMA (Direct Memory Access) controller, that helps the processor to communicate with I/O devices without doing memory-intensive tasks.A 32-bit core, that allows the transfer of 32 bit wide data per a single CPU clock.The microcontroller on Arduino Due is based on 32 bit ARM core microcontroller i.e, Atmel SAM3X8E ARM Cortex-M3 CPU Introduction to Arduino Due Pinout: Introduction to Arduino Due parts Arduino Due pinout, specifications, schematic, and datasheet is given below. Arduino Due pinout is explained in detail in this post.Īrduino due board features 52 digital input/output pins, an 84 MHz clock, two micro-USB ports, an SPI header, a JTAG header pins, an ERASE button, and a RESET button. This board is powered by a 32-bit ARM cortex-M3 processor Atmel SAM3X8E. It was launched by Arduino company in 2012. The Arduino Due is one of the most powerful boards of the Arduino series.
