This is not recommended because you bypass the NCP1117 voltage regulator and have to make sure that the voltage level is stable. You can also power power the Arduino microcontroller from the 5V pin. You cannot power the board with the barrel jack and VIN GPIO at the same time, because there is a polarity protection diode, connecting between the positive of the barrel jack to the VIN pin, rated at 1A. Therefore you are able to power the Uno with an external 9 Volt battery. The voltage has to be between 7V and 12V. VIN Pin: If you use an external power supply like a battery, you can use the VIN pin.If you buy a DC power jack, make sure the power adapter of the plug supplies a voltage between 7V and 12V. DC Power Jack: It is possible to use the DC power Jack as power supply.The standard USB connection delivers 5V and allows you to draw 500mA in total.

USB cable: The most popular and also the easiest way to power the microcontroller is via USB cable. Well discuss the features of each board, provide an informative pinout diagram with tonnes of detail, and toward the end of the article, provide a tab. The Mega 2560 is an update to the Arduino Mega, which it replaces.

And everyone has their own pinout headers. All of the modules can work together or separately.

You can power your Arduino Uno in 3 save ways because a voltage regulator provides a regulated and stable voltage for the microprocessor: Mega +WiFi R3 Atmega2560+NodeMCU ESP8266 32Mb Memory USB-TTL CH340G Compatible For Arduino Mega is Full integration on one board Mega R3 ATmega2560 and WiFi ESP8266 with memory 32Mb.

The 5V pin of the Arduino Uno is directly connected to the 5V voltage regulator and supports a maximum current that is defined by the difference of the current provided by the voltage regulator and the current from the ATmega328p. I never needed more than 50mA on the 3.3V pin, but in my opinion, a current draw of around 100mA should be possible. Regarding the data sheet of the LP2985, the maximum current is 150mA but on the official Arduino website, the maximum current should be 50mA. The second voltage regulator, 3.3V LP2985, has an input voltage of 5V and reduces the voltage to 3.3V for the 3.3V pin of the Uno. The maximum current draw from the USB connection is 500mA.

There is no need for a voltage regulator because the USB connection is already regulated by the USB output from your PC or laptop. The ATmega328p can also be powered via the USB connection, that I use a lot in my projects. The NCP1117 provides a stable output voltage of 5V and a maximum current of 800mA for the ATmega328p. Technically the maximum input voltage is 20V but because at 20V the voltage regulator is producing a lot of heat and would break after a short time period, it is recommended to supply an input voltage between 7V and 12V. The Mega 2560 R3 works with all existing shields but can adapt to new shields which use these additional pins.The NCP1117ST50T3G is connected to the VIN pin and the DC power jack. The other is a not connected and is reserved for future purposes. One is the IOREF that allow the shields to adapt to the voltage provided from the board. In additionthere are two new pins placed near the RESET pin. The Mega 2560 R3 also adds SDA and SCL pins next to the AREF.

The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (FlashProcessingMaxMSP). Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language.
