The onboard regulator is linear so theoretically, ignoring any chip-specific limitations, you can't draw more current than you put in. 12V@2A in == 5V@2A out, the rest of the power 14watts is burned as heat in the linear regulator! This said, the regulators specced limit is 800mA, but thermal dissipation is going to keep you down in the 400-500mA range Absolute Max, 40mA per pin, 200mA VCC or GND current. 20mA per pin recommended max. A huge note, various ports have individual limits: 3: Although each I/O port can sink more than the test conditions (20mA at VCC = 5V, 10mA at VCC = 3V) under steady state conditions (non-transient), the following must be observed: ATmega1281/2561
I want to power an external wireless and display device from the Mega's 5V supply. Can anyone tell me the maximum current taken by the Arduino Mega 2560 and the Arduino Ethernet Shield. I can't find this specified anywhere. I believe that the 5V regulator is capable of delivering 800mA. Thanks. Well the answer depends on a lot of variables. USB power or external DC power through the external power connector 5 volt output max current for Arduino Mega 2560 rev3. Well I've looked and looked and just cant find data on the max current of the 5 v output (or even a suggested reasonable max) They all mention 50 mA for the 3.3v output. Looking at the chip it's a smaller board than the Arduino Uno so I don't want to pop it
.5V to +5.5V (the actual max is Vcc + 0.5V, which for a 5V Arduino, is +5.5V) (Note 1) Output Current Limits: When powered by USB: total of 500mA; With external battery or power supply: total of 500mA~1A (see below for specifics) 5V pin: same as above: 500mA or 500mA~1A; Each input/output pin: 40m The Arduino Mega has in total one 3.3V pin and four 5V pins, which are able to provide a current up to 50 mA. The VIN power pin can also serve as power supply for the microcontroller with a voltage range between 7V-12V it through this pin. 5V. The regulated power supply used to power the microcontroller and other components on the board. This can come either from VIN via an on-board regulator, or be supplied by USB or another regulated 5V supply. 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA. GND. Ground pins. Memor 5V. This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it. 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA
5V or 3.3V Power - The designer can apply the appropriate voltage to the 5V or 3.3V power pins of the Arduino. These pins are tied directly to the power pins of the MCU on the Arduino board. However, applying power to these pins will cause the MCU of the Arduino to be susceptible to the line loss and contact resistance loss from the power source mentioned earlier .5V, the top diode starts to conduct current. This is OK for diverting a short-duration overvoltage event, like ESD (electro-static discharge), but that diode is not meant to be on all the time. It will simply burn out and stop protecting the pin RE: Arduino USB und 5V Stromversorgung. So mach ich das auch immer, einfach ein kleines Netzteil an Vin zusätzlich anschließen. Nur über USB versorgen kann bei höherer Stromaufnahme zu komischen Effekten führen, z.B. wenn noch ein Display angesteuert wird. Dann hatte ich nur aus dem USB versorgt nur noch 4,6V. Gruß, Holger
Arduino-mega 2560-board-pin-diagram. Pin 3.3V & 5V. These pins are used for providing o/p regulated voltage approximately 5V. This RPS (regulated power supply) provides the power to the microcontroller as well as other components which are used over the Arduino mega board. It can be attained from Vin-pin of the board or one more regulated voltage supply-5V otherwise USB cable, whereas another. Since the Arduino operates at 5V it can't control these higher voltage devices directly, but you can use a 5V relay to switch the 120-240V current and use the Arduino to control the relay. The Arduino can be programmed to turn on the relay when a certain event occurs, for example when the temperature of a thermistor gets higher than 30°C VIN Pin: If the current consumption exceeds 100mA you should power the Arduino Nano via the VIN pin. The voltage has to be between 5V and 12V. Therefore you are able to power the Nano with an external 9 Volt battery. You can also power power the Arduino microcontroller from the 3.3V pin or the 5V pin The 5V pin header is connected directly to the 5V rail. Beacuse the Jetson has no 5V regulator, the current limit on that pin is the same as the current limit on your power supply, minus anything consumed by the Jetson and any USB peripherals you have

When you set the output pin to gnd, you are sinking current to the output, meaning flowing current from 5V to the output pin through the LED and resistor.

1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. The second one is a not connected pin, that is. Hi all, I was using MAX30102 and had the same issue. I solved the problem by using 1 pull-up resistor (4.7 kohm) for SDA pin and another one (4.7 kohm) for SCL pin. Vin was connected to 5V of Arduino and also both pull-up resistors were connected to 5V

Arduino Due or Taijiuino Due could supply max 800mA current through 5V supply. So it works but leaves not much current allowance for other modules. 2) Supply 7~16V through the power jack on the TFT shield
Introduction. This DC Motor shield for Arduino uses L293 chip which allow to drive two 7-12V DC motors with maximum 1A current each channel. This shield can be directly stacked on standard Arduino Uno and Arduino Mega . Integrated XBee Slot, XBee, WiFi Bee, Bluetooth Bee, I2C. Mirrored version of DRI0009 Arduino digital outputs can only supply +5V (or +3.3V) and less than 40mA max. (typically <20mA for continuous use). So, except for some reed relays, you cannot drive the relay coil directly from the digital output since 5V power relays typically require ~100mA to operate the relay coil. This means for most (all) relay modules you need to provide a separate supply to the module in addition to.
