Arduino Uno Wall Adapter

fechrxy
fechrxy over 12 years ago

Hey guys, I am brand new to this Arduino type stuff and am planning on buying an Arduino Uno tomorow. Along with the Uno i would like to buy a wall adapter to power it, but the only problem is that i don't know "EXACTLY" which wall adapter to get and I would like to know "EXACTLY" which wall adapter to get. The reason I want such "EXACTNESS" is because i have found multiple websites that offer wall adapters for the Uno, all of which have generaly the same technical specifications exept for in a few areas, one of which is the mA. Some provide 650mA and others 1000mA (I will include links to wall adapters i found at bottom) i would like to know the "EXACT" amount of mA i should look for in a wall adapter (Unless the correct amount of mA varys by amount of power required) for the Arduino Uno so that i don't over heat or under power it. Another technical specification that varys is whether or not the adapter is a Wall Wart or not. So i need to know proper mA, whether or not i should get a wall wart, and it would be great if you could "PROVIDE A LINK TO A SPECIFIC ADAPTER"!!! also any additional information that might be needed. Sorry for the lengthiness and spelling errors, but here are links to a few of the wall adapters i was previously refering to ----> https://www.sparkfun.com/products/298

    There is no EXACT answer, they all will do great. The reason for the diversity is that the arduino is a building block, and has on board regulators for 5V and 3.3V. - if you read and report temperatures…

    It is smarter to use a 6V power supply, because just as you suspect, the rest is "regulated" away. This is more important for more power hungry projects, but for less power hungry projects it doesent really…

    For those rare cases when I needed it to be powered independently from my computer, I've simply used the power adapters for my cell phones to provide power through the USB connection. The iPhone cubes are nice for that, with 1A of power image

     

    Cheers,
