So I read (and was advised) that a well regulated 5V supplied directly to arduino 5v pin can power it up. I am using a 12V 5A supply and stepped it down using L7805 regulator in below configuration. Only it is stepping it down to 4.95V as checked in my multimeter. Is it Fine or must it be 5V exactly…

[image] anon90086852: Is it Fine or must it be 5V exactly? 10% tolerance is usually assumed, if not stated, so 4.5 to 5.5V. However at 5.5V you are getting uncomfortably close to the absolute maximum operating voltage of 6.0V. As previously mentioned the MCU itself will operate at much lower…

What tolerance does Arduino have for powering it through 5V pin?

Bigger heatsink - more mass, more metal.
