ARDUINO MEGA 2560 POWER INPUT PIN PRO

You can't use a 5.0V dc supply on the Vin pin because of the voltage drop across the regulators. An on-board voltage regulator typically accepts 7V to 9V dc but, will handle voltages as high as 18V dc. The board can be powered directly through the micro-USB connector, or via the Vin pin. These are covered in more detail on my Smartisant website. The board is compatible with Arduino Mega 2560.

ARDUINO MEGA 2560 POWER INPUT PIN PRO

The Mega Pro Embed CH340G / ATmega2560 board is based on the ATmega2560 microcontroller and the USB-UART adapter CH340.

The maximum output current from the 5V on-board supply is 800mA and the 3.3V supply is also 800mA. The voltage regulator operates in a range of 6 to 9V DC. The board can be powered directly through the Micro USB connector or via the V in pin. The board has a micro USB connector to allow you to connect the microcontroller to the computer and to use the Arduino IDE. The Arduino Mega Pro (Embed) CH340G / ATmega2560 board is based on the ATmega2560 microcontroller and the USB-UART adapter CH340 and is compatible with Arduino Mega 2560, with identical functionality.

I2C support exposed via a 4-way Molex connector.

24 digital IO connections exposed via 3 10-Way DIL connectors.

8 digital IO pins exposed via 4-way Molex connector.

6 analogue inputs exposed via 4-way Molex connector.

The objective is to create a very small, powerful, cheap, single board slave processor with Ethernet connection and lots of IO capability.

This is an 'embedded' version of the Mega 2560 and is much more compact. The focus of this project is to evaluate and integrate the Arduino Mega 2560 Pro into our contextual smart home, so that it becomes another one of our smart home building blocks.
