RTC modules - perfect electronic tools for standard and emergency timing

Real-time modules are tiny electronic boards for computer systems that measure time precisely. Their great advantage is that they can operate completely independently of the machine they are connected to. What's more, they can also work after a power failure from the main power supply or battery. A power outage or a failure of the power supply system will not affect the RTC modules. Although today we often use additional protection and backup power (most often it is an additional lithium battery or a small battery), independently operating RTC modules are still the best method when it comes to time measurement. For this type of small module, it will not be terrible to change the current consumption, nor to perform immediate leap year calculations or check how many days there are in a given month. All about timing is a perfect job for recommended RTC modules that you buy in this Botland store category!

RTC time modules for Raspberry Pi systems

RTC modules - real time clocks - are small but advanced devices. Their advantages will surely be appreciated by enthusiasts of programmable electronics. Although the more advanced microcontrollers - Raspberry Pi, Arduino - already have the appropriate built-in unit and can measure time, some developer models still do not have such options. What then needs to be done so that our electronic project always has precise access to time, hours and dates? It is enough to install the proven RTC module.

In this category you will see many RTC modules that are fully compatible with Arduino and Raspberry Pi minicomputers. The Raspberry Pi Real Time Clock can do very simply by adding such a module to the main board of the device. When browsing the individual modules, just make sure that the product in question can be installed as a Raspberry Pi RTC. In our store you will find both small, cheap modules in the form of plates attached with goldpins, as well as fabulously easy to use arduino shieldy and plates dedicated to the Raspberry Pi.

RTC modules for programmable electronics

RTC modules for Raspberry Pi and other electronics may increase your projects' possibilities. These types of clocks are easily compatible with many other parts, so installation is not much of a problem. Despite so many functions, the presented RTC modules usually come in the form of small PCBs. The size of the module is primarily determined by the type of connector and the type of battery or accumulator installed.

Some of the modules impress with their small size - thanks to this, they are ideal for mounting in small devices and wherever the amount of space is particularly limited. A good example is the Tiny RTC module, whose external dimensions are not much larger than the diameter of the popular small CR2032 battery. Sometimes it may be that replacing the battery in a given device would cause technical complications or it is simply impossible, so in such circumstances dedicated RTC modules will do a great job. For such applications, consider buying a module with a maintenance-free supercapacitor, which you can also find in this catego
