Arduino is a simple board of small size with great potential for extension. It can be used for simple meteorological stations as well as advanced building automation systems. Arduino modules are chosen by experienced electronics engineers and amateur DIY enthusiasts. The tiles can be used in many ways. However, in order for the resulting device to function and its potential to be fully utilized, an appropriate power supply is necessary. It is possible to choose the way of powering Arduino. The easiest way is to connect USB cable. The alternative is external power supply, which you can connect in several ways, choosing the best and most suitable one for your project and your convenience. Without proper power supply Arduino will not fulfill its intended function. The system will not work and its lifetime will be limited. It will also lose its reliability, for which Arduino is appreciated by professionals and amateurs.
Module for connecting a mobile power source for Arduino. It allows you to power the microcontroller from any battery voltage from 3 V to 4.2 V or solar panel voltage from 4.8 V to 6 V. It provides a stable 5 V and a maximum current of 600 mA.
Switching power supply Spotlux in black color, is used to supply the devices with voltage of DC 12 V. input Voltage ranges from 100 V to 240 V frequency 50 / 60 Hz. Output voltage 12 V output current 3 A. the External connector 5,5 / 2,1 mm Adapter has a cable length of 140 cm and a removable adapter EU.
You will supply power to all Arduino circuits by connecting it to your computer using a USB cable. This is the simplest and most common way to power the board. It is also due to the ability to communicate immediately after connecting the board. Communication takes place through the virtual serial port. However, it is not an ideal solution that is always worth using. Sometimes the current is too low for a powerful motor and additional actuators. This is the case with the USB 2.0 standard, where the supplied current can be up to 500 mA. An alternative to the USB cable is a DC socket. It is located in Arduino Mega and Arduino UNO, among others. It is recommended in case more power needs to be supplied to the Vin line.
In our offer there is a wide range of plug and desktop power supplies. With their use you will be able to power Arduino via 5,5/2,1 mm DC plug. This type of power supplies are characterized by slightly larger dimensions than the plug connectors, which have lower current capacity but small dimensions. Desktop power supplies usually have a detachable mains cable terminated with a typical plug. You'll find power supplies that range from 1.5A to 2.5A and desktop power supplies that range from 1A to 5A. In each of these cases, you will find an output voltage of 12 V or 5 V.
Renewable energy sources are becoming increasingly popular. In recent years, the awareness of our impact on the environment has increased significantly. We know that we can use energy sources that are inexhaustible and do not harm our environment. Thus, we often look for solutions that would allow us to use them. One of them is the Solar Charger Shield cap. It is a relatively cheap option, but very practical and functional, and what is important, ecological. The cap enables powering the board with a 1S 3.7V lithium-polymer battery. It is charged by a solar battery with a voltage from 4.8 to 6 V. It is also possible to work with batteries whose voltage ranges from 3 to 4.2 V. In addition, the Solar Charger Shield can work with a micro USB socket. This is a practical solution, especially since the power supply does not occupy any signal line of the microcontroller. This means that the possibilities of using the target application are not limited in any way.
Power supply is crucial for efficient and correct operation of Arduino board and the whole application. There are several possibilities to provide it with the power it needs to operate the system. You can use the most common option, namely USB cable and DC socket. If you are a supporter of renewable energy sources, then choose the Solar Charger Shield cap that allows you to draw power from the sun.
