![]() VIN Pin: The board can also be powered by an external power supply connected to the VIN pin.The voltage range for this method is 7-12V DC. External Power Supply: The board can also be powered by an external power supply connected to the DC jack.This is the most common method of powering the board during development. USB type B: The board can be powered by connecting it to a computer via the USB type B connector.The power supply options for the Arduino Mega ADK are: It has a voltage regulator on board that converts the input voltage to the appropriate voltage for the microcontroller. The board can be powered through the USB Type B connector or an external power supply. The Arduino Mega ADK's microcontroller (ATmega2560) can handle the maximum voltage of 5.5V DC. LEDs: The board utilizes several LEDs, including a power LED, a pin 13 LED, and a RX and TX LEDs which indicate when data is being transmitted or received.Power Jack: The board has a 2.1 mm center-positive power jack, which can be used for connecting an external power supply, such as a battery or wall adapter.In those scenarios the board acts as the USB host. The other is USB type A connector that can be used to connect other USB devices to the board. One USB type B which can be used for programming the board and for providing power to the board. ![]() USB Connector: The board has two USB port.ICSP Header: The ICSP header is intended for programming the board with an external programmer.Reset Button: The reset button can be used to restart the microcontroller or to put it into bootloader mode for uploading new sketches.The board also has a VIN pin, which is the input voltage to the board when it is powered by an external power supply. 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. These connectors are gold-plated, rated current of 3A, very compact.ġ1.On the SD card to add - is now available from the Kliment - Sdramps.ġ3.Option 2 motors connected to Z Prusa Mendel.Arduino Mega ADK Rev3 Pin Headers and Components ģ.Heater / MOSFET outputs and three fan thermistor circuit.Ĥ.Integration of additional security 5A and component protection.ĥ.Control of additional heating bed 11A fuse.Ħ.Suitable for 5 Pololu stepper driver board.ħ.Pololu board pin socket, so they can be easily replaced or removed for future designs.Ĩ.I2C and SPI pins left for future expansion.ĩ.Hooked into all MOSFET PWM pin versatility.ġ0.Servo type connector is used to connect to the end stop, the motor and the light-emitting diodes. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.ġ.It has Cartesian robots and regulations of the extruder. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion. RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty room for expansion. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RepRap Mega Pololu Shield, or RAMPS for short.
