It is surprising how the development of electronics has reduced the requirements for energy sources cooperating with computers. Until recently, the term "computer power supply" could at first be associated with a fairly large ATX power supply, offering power of at least several hundred watts. Today, truly powerful single board minicomputers require a single input voltage (usually 5V or 12V) and a current capacity of only a few amps to operate. And yet - also in this case you can make a number of mistakes when choosing a power supply for your minicomputer - it is worth knowing what requirements LattePanda modules pose in this respect.

Choosing a power supply for a minicomputer - a short guide
The basic parameters of each power supply are, of course: nominal voltage and maximum current efficiency, and thus - also the value of the output power, which is the product of both of the above. In the case of LattePanda V1 minicomputers, the voltage is supplied via the microUSB port - the recommended power supply parameters are 5 V / 2 A, and in the case of much more powerful LattePanda Alpha modules, a power supply with 12 V / 3 A output, equipped with a USB C plug, is required to run the computer. add that the last of the mentioned series of minicomputers can also work with a lithium-polymer battery, which significantly facilitates the practical implementation of SBC in utility applications. Regardless of the model you choose, remember that the power supply parameters provided by the manufacturers usually refer to normal operating conditions - if external devices powered from its ports (e.g. USB accessories, touch screens, hard drives, overlays, etc.) are to work with the minicomputer, then the total system power consumption will be correspondingly higher. Therefore, the power supply used should always offer a certain margin of safety (power reserve), usually in the range of at least 20% of the value of the total power consumption of the minicomputer and the accessories attached to it.
Branded accessories for LattePanda minicomputers
In our offer you will find a wide selection of power supplies, designed to work with the most popular models of single-board minicomputers. For example, for the LattePanda series in the V1 version, we offer an excellent, dual-output Extreme microUSB + USB A power supply: a well-thought-out design combines the features of classic chargers for mobile devices (hence the USB A socket in the upper part of the housing) and plug-in power supplies with a factory-installed cable (in this case terminated microUSB plug). This solution is ideal for cooperation with minicomputers, because it allows for simultaneous power supply of the main module itself and an additional accessory, e.g. a display connected via the HDMI port.
