The max recommended dissipation for the regulator is 1 Watt. The Atmega2560 on the Arduino Mega comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. This link says 800mA is the max, or 200mA per pin. cable or power it with a AC-to-DC adapter or battery to get started. 5 So digital IO pins are compatible with 3. Currently, I am looking for a DC-DC converter to lower my voltage to 5 V, but I figured I don't know the maximum current the Mega will draw. In order to install my project in the boat , I guess I must reduce the power source (coming from 12v batterybank to 5v. For 12V into Vin that works out to 1/(12-5) = 1/7 or 143mA*. My question is that would it give 500mA to each +5V pin, because each Arduino Mega has around 3 or 4 +5V pins. Most the time they will not be on at the same time but I do hope to have all 70 on at the same time periodically. While you didn't ask this question, you should keep in mind that those small rectangular 9V batteries are very lousy when it comes to current capacity. So the current from the Arduino pin flows back to the Arduino power supply and the current through the motor flows back to the motor's power supply. 5A? FYI, I've got Arduino Leonardo and probably it was damaged because of that external power supply. The chip has an upper limit of 200mA for all processing and IO combined, and there are low-power sleep modes that only draw a few microamps. 6VCC to max VCC + 0.
