Arduino power supply

Arduino power supply methods

The most basic method of supplying voltage to all Arduino circuits is to connect the device to a computer via a USB cable. Arduino boards allow for such a solution, making everything much simpler. We can immediately communicate via a virtual serial port and use Arduino functions through the computer. For obvious reasons, this method also has its drawbacks. The power supply from USB is not ideal - in the USB 2.0 standard it can provide a current of up to 500 mA, which is not enough for most motors and many other actuators. In addition, we often build more advanced self-made structures that are to work independently without being connected to a computer or laptop. In such situations, it is worth considering purchasing an Arduino power supply module. Powering the board through the DC socket, which you will find, for example, on the Arduino UNO and Arduino Mega boards) will ensure a higher level of self-sufficiency of our electronic design. These types of Arduino power supplies can provide much more energy, so you will have no problem connecting motors, controls or advanced sensors.

Arduino power supplies

In this category of our store you will find various types of Arduino power supplies modules - plug-in and desktop type, which will allow you to power the platform via a 5.5 / 2.1 mm DC plug. Plug-in power supplies usually have lower current efficiencies, but on the other hand, their dimensions are very small. Visually, this type of Arduino power supplies will remind you of standard cell phone chargers. Power supplies in desktop casing have slightly larger dimensions, but as a result - they are much more durable and have better current efficiency. What's more, they have a detachable network cable, terminated with one of the typical plugs. When choosing the type of Arduino power source, you should first check what power requirements your project or Arduino board has. It depends on what type of power supply to choose. In the Botland store you will find everything you need - plug-in power supplies with a capacity of 1.5 A to 2.5 A and desktop power supplies from 1 A to as much as 5 A. All power supplies have an output voltage of 12 V or 5 V.

Solar Charger Shield - ecological Arduino power supply module

No doubts renewable energy is the future. If you are interested in green technology, we have a must-have product for you! Inexpensive, but very functional and modern, Solar Charger Shield is an ecological Arduino power supply module that you can connect to many of your boards. Thanks to this module, you can power the Arduino with a 1S 3.7 V lithium-polymer battery, charged by a solar battery with a voltage in the range of 4.8 to 6 V. The overlay also gives you the ability to work with batteries with a voltage from 3 to 4.2 V and also with a micro USB socket. That's not all, because in the factory configuration, the power supply does not take up any signal lines of the microcontroller. This means that it does not in any way limit the possibility of using Arduino in the target application. Are you looking for a modern Arduino power source? You just found them!
