![]() It has 54 digital I/O pins, 16 analog inputs, and up to 40mA per pin. Arduino MegaĪrduino Mega, on the other hand, is a larger board. Arduino Uno is ideal for beginner-level projects, where you don't need to use more pins or complex components. It's also less expensive than other Arduino boards. With its compact size, you can easily fit it into tight spaces. It’s easy to use and doesn't require any external hardware. With 14 digital input/output pins, 6 analog inputs, and a maximum of 20mA per pin, Arduino Uno is suitable for small projects. It's a small board that uses an ATmega328P microcontroller. Arduino UnoĪrduino Uno is the most popular board from the Arduino family. Both boards are fantastic options, but which one to use? Read on to find out. But choosing between Arduino Uno and Arduino Mega can be confusing, especially if you're new to the world of microcontrollers. Arduino Mega - Which is Better for Your Project?Īrduino has been a go-to option for DIY electronic projects. Arduino Mega - Which is Better for Your Project? Arduino Due clones are for getting extra on-board features.Arduino Uno vs. ![]() Due does lack ready to use many of the “shields”, all code & library may not work. It does not means you’ll throw away Arduino UNO. We would say – it is a expensive, easy starting to get rid off n00b grade electronics. You can actually use ATmel Studio instead of Arduino IDE. Official Arduino Due is really good for the relatively newbie interested in “real electronics”. So many features actually yet short to compete with Arduino compatible STM32 ARM Cortex M3 Boards for that price and also features. Obviously, Arduino Due supports other IDEs. The real issue is the lack of RAM, but the DUE can support external RAM. But a shield which needs 5V power to respond will not work with Arduino Due. We actually power higher voltage things like motor by external power with star configuration of power supply. Actually we fear, cross-check to use 5V pin out of works with 3.3V. Why 3.3V? 3.3V logic is more popular than 5V logic outside hobby-grade components, outside the Arduino ecosystem. It is possible to erase the Flash memory of the SAM3X with the onboard erase button which will remove a loaded sketch from the MCU. The board can connect to a computer with a micro-USB cable, compatible with all Arduino shields that work at 3.3V, and almost all sketches. ![]() The Arduino Due uses Atmel SAM3X8E ARM Cortex-M3 CPU with 54 digital input/output pins, 4 UARTs, a 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button. The Atmel QTouch Library is available for easy implementation of buttons, sliders and wheels. It’s 16-bit external bus interface supports SRAM, PSRAM, NOR and NAND Flash with error code correction. SAM3X8E features a 12-bit ADC/DAC, temperature sensor, 32-bit timers, PWM timer and RTC. There was Arduino Tre, which has faster ARM. The Arduino Due is much more powerful in comparison to Arduino Uno :ĭigital Pins (input/output) : 14/6 vs 54/12Īnalog read : 10 bits resolution vs 12 bits resolution (*4) We need to keep Arduino UNO as standard Arduino board to compare. Arduino Due does fall among such possible to “recommend Arduino board”.ĭifference of Arduino Due With Other Arduino Boards Usually we recommend Arduino boards which are widely accepted, likely to stay on the market, globally available, cheap China clone available. The board is faster, specially with graphics and good for robotics to many works. Difference of Arduino Due With Other Arduino Boards is the 32-bit ARM Cortex M3 Microcontroller Which Forces the Board to Supply Maximum of 3.3V. ![]() The bootloader is preburned in factory from Atmel and is stored in a dedicated ROM memory. Arduino Due is basically official version of those boards. In our one previous article, we discussed about STM32 ARM Cortex M3 Boards which can run Arduino. ![]()
