Linear regulators are, at best, only around 70% efficient. Means that Vin - Vout is 2V and the usual current drawn is 1A. You can calculate the power that gets wasted in the form of heat with a simple equation: Pwasted = (Vin - Vout) * Iįor 5V output, 7V in given as input to to regulator. The downside of a linear regulator however is they can get pretty hot when you have a large difference between the input and output voltage, or if you’re drawing a lot of current. They’re cheap and can regulate a higher voltage to a lower voltage with as few as 3 pins (Vin, ground Vout). So, it will not reduce the functionality of the Arduino. It is just to show that Arduino is on or off. I will tell you other alternatives for programming the micro-controller later on. The Arduino Uno has a USB bridge that converts the USB signals to signals that the Arduino’s Universal Asynchronous Receiver Transmitter (UART) can use. By reducing the number of ICs needed, you can save a bit of power.

So, let's see what can we remove to lower the power consumption on our homemade Arduino.Įvery integrated circuit (IC) needs power to function. But, if you have basic knowledge and experience of working with Arduino then, you can avoid those parts and can check the circuit for any mishap. No, actually most of the components of a Arduino board are for preventing short circuiting, damage control, etc. Making it seems to be difficult having a lot of components. In this guide we’ll see if we can reduce the supply current to less than 10uA with a couple hardware and software tricks. The RedBoard and Arduino Uno, draw around 15mA minimum, which doesn’t sound like much but as you’ll see in this project, we can drastically bring that down with just a few tricks. The ATmega328P, used on popular boards like the SparkFun RedBoard, Arduino Uno, and Pro Mini are actually quite power hungry. When it comes to portable electronics, one of the most important features is how to maximize the battery life.
