![]() Power Pins: Arduino Mega ADK have several power pins, including 3.3V and 5V pins, which can be used to power other devices or sensors.Analog Input Pins: The board provides 16 analog input pins, which can be used for reading analog sensors, such as temperature sensors, light sensors, and potentiometers.15 of these pins can also be used as PWM outputs for controlling the brightness of LEDs or the speed of motors as an example. Digital I/O Pins: The board has 54 digital input/output pins, which can be used for a variety of purposes, such as reading sensors, controlling LEDs, and communicating with other devices.Dimensions: The board measures 101.52mm x 53.3mm.Here are a few of the most important components and connectors to be aware of: The Arduino Mega ADK is a relatively large development board that is packed with a variety of components and features. I think it will work and be compatible if powered from 5V, but will not work if powered at 3.3V, because the input to the regulator is too low.Arduino Mega ADK Rev3 Pin Headers and Components Sdramps (AUX-3 SPI connector) This board has a 5->3.3 voltage regulator and a level translator.Mechanical endstops should be OK, if they do not use external pullup to 5V.Thermistors will operate at 3.3V but the Analog Ref is also 3.3V, so no changes should be necessary.Servos "should" be able to operate with +5V power and a PWM signal of 3.3V.This should apply to all the Pololu style drivers. The Allegro stepper drivers will run with VDD = 3.3V and the logic signals compatible with 3.3V.(AUX-3) The SPI pins on the Mega (mapped to pins D50-52) are not SPI pins on Due.Some opto-endstops need 5V power, and return 5V on signal.Is heat dissipation of Due ok with RAMPS shield over it?.Add ons: SD card, thermocouple drivers, LCD boards.Expansion pins need to be level-translated, but this depends on how they are used.MOSFETs need to be compatible with threshold voltage of 3.3V or better have a gate driver which allows any MOSFET to be used.The SPI port is only routed to the 6 pin header used for ICSP on Mega, but this is not used for ICSP on Due. The Due has 1 dedicated SPI port, and 4 multipurpose USART/SPI ports.CPU package has an absolute max of 130mA.Low-current IO pins capable of 3 mA source, 6 mA sink.High-current IO pins are capable of 15 mA source, 9 mA sink. ![]() Significant differences between Arduino Mega and Arduino Due SMART_RAMPS another version of RAMPS for Due & MEGA2560 See page RAMPS_Interface_Board SMART RAMPS RAMPS-FD is another version of RAMPS for Due. ![]() As well as it can be used with Arduino Mega, Re-ARM and Adafruit Grand Central M4 RAMPS-FD RAMPS_1.4.4 can be used with Arduino DUE. RAMPS 1.7 can be used with either of Arduino Mega or Arduino DUE I don't know much about this, apart from the web page RADDS für den Arduino Due. RADDS is a version of RAMPS designed for Due. create a RAMPS Interface Board (RIB) to sit between Due and RAMPS to perform level-shifting, and any other needed functions. ![]() Possibly could also be made backwards compatible with Mega. create a new RAMPS variant which is compatible with the Due.Therefore there are several possibilities: Worse, applying 5V to the Due's inputs will likely damage the chip. RAMPS for Arduino Mega is a popular platform, but RAMPS is not compatible with Arduino Due, mainly because the Due is 3.3V based and not 5V compatible. 3.4 Hardware features known to be compatibleĪrduino Dueis an Arduino board that is using an ARM Cortex M3 CPU.ĪVR variants of Arduino are widely used by RepRap electronics, but the new Arduino Due is not compatible with AVR chips, partly because the Atmel SAM3X8E chip used on the Due operates at 3.3V and is not compatible with 5V, and also the Due requires firmware compiled for ARM Cortex.3.2 Significant differences between Arduino Mega and Arduino Due. ![]()
