BeagleBone memory cards

BeagleBone memory – loads of data in one tiny plastic

BeagleBone is very fast, roomy and convenient to use. In one small piece of 'plastic' you will fit the entire operating system for your electronic project! You just need to remember to choose the right card. To do this, follow the most important criteria.

When choosing a memory card to work with a single-board minicomputer, such as BeagleBone, you should pay attention not only to its capacity. The most important parameters include the speed of data transfer and the speed of data writing on the memory card. These values ​​result from the processor technology used in a given solution. These speeds are also directly influenced by the design of the card itself. Today, the communication interface is no longer a major problem. Virtually all major digital systems support cards with a high-speed SDIO connection. Still, the most important thing is the access time to the memory areas of the card. A card's speed is determined by its class. The higher the class of the memory card, the shorter the time it takes to write or read data.

BeagleBone and the memory cards’ classes

As we have mentioned before, the memory card class reflects the speed of its operation (writing, processing and sending data). In the case of efficient BeagleBone computers, class 10 memory cards will work best, because they are products that offer high speeds at the level of several dozen or even 100 MB / s.

Of course, in the case of not very demanding tasks, slower cards (e.g. class 6) can also be a good choice. However, if we want to try to play a movie in HD quality or support three-dimensional graphics, it is necessary to ensure faster data transfer. If you plan to use your BeagleBone to work with a camera or acquire large amounts of data, a fast class 10 card will be the only right choice. Estimate your own needs and based on this analysis, choose a memory card with the speed class that suits you best!

Memory card with or without a reader? That’s the question

Currently, it is less and less common for the manufacturer to offer us a memory card that does not have additional accessories and functionality. Due to the fact that there are many USB readers and other similar devices, full-size SD cards are still often used. Usually they can be purchased in a set with a micro SD memory. A simple adapter is a practical device into which you can insert a small memory card. The device will read data from it without any problems. But that's not all.

The Botland online store also offers kits with a convenient USB OTG reader. It allows you to work with the card both from a computer with a classic USB A port, as well as with a phone that supports the USB OTG standard. The latter solution is especially useful if you want to quickly use the memory card from the phone. For this purpose, it is enough to connect the reader, we do not have to change the card in the phone slot.
