UNO and NANO cannot provide analog output which is need in some applications. So when there are many peripherals in an application using DUE is ideal.Ĭase3: Where application needs to provide analog output. With 84MHz clock speed more than five times speed of UNO, DUE could do process more data than UNO or NANO.Ĭase2: Where you need to connect more peripherals. They cannot process high end programs for applications like 3D printer. UNO or NANO are boards, which have a maximum clock speed of 16 MHz, so they can perform functions limited to their capabilities. There are few cases where DUE is chosen over other Arduino Boards:Ĭase1: Where the system processing is huge. So you can customize the system depending on the need. Also, the ARDUINO DUE is an open source platform where one can get all related data and original module schematics. Though it is least popular, it is most recommended when designing complex systems like CNC or 3D printer. RASPBERRY PI SERIES, INTEL GALILEO, INTEL EDISON, ESP32Īlthough ARDUINO boards are usually popular, DUE is least popular because of controller being ARM and I/O pins +3.3v OUTPUTS are not compatible with most sensors. Maximum total current drawn from all I/O pinsĪRDUINO UNO, ARDUINO MEGA, ARDUINO NANO, ARDUINO PRO MINI, ARDUINO LEONARDO In DUE board all I/O pins can be used as Interrupts.ĭUE has internal Temperature sensor which can be programmed to read temperature.ĭUE has RTC with CALENDER and ALARM features, which can be enabled internally. These 12 channels can provide PWM (Pulse Width Modulation) outputs. There are two channels which can provide Analog output. These channels can be used to input Analog signals. SSC(Synchronous Serial Communication) Interface can be used for Audio and Telecom ApplicationsĪlthough these 54 pins have many functions, they can be considered as data I/O pins. TWI (Two Wire Interface) Interface can be used to connect peripherals.ĬAN (Controller Area Network) Interface can be used for communication between controllers

SPI (Serial Peripheral Interface) Interface ban be used to program PRO MINI UART (Universal Asynchronous Receiver Transmitter) Interface can be used to program PRO MINI SPI Interface(MOSI, MISO, SCK ,RESET) x 1 DUE board also developed on ARM controller series whereas other boards are developed on ATMEGA controller series.

It could be considered as a professional board considered UNO as a beginner board. DUE board not only has tons of features but also has terrific processing speed making it suitable for advanced applications. ARDUINO DUE board is one of the most powerful development boards in the ARDUINO series.
