Micro SD Card Module
The Micro SD Card Module is a compact storage interface designed to enable microcontrollers and embedded systems to read from and write to Micro SD and Micro SDHC memory cards. Using a standard SPI communication interface, the module provides an easy method for data logging, file storage, and data transfer applications. It includes an onboard voltage level conversion circuit, allowing compatibility with both 3.3V and 5V systems such as Arduino, AVR, PIC, STM32, ESP32, and Raspberry Pi. Supporting memory cards up to 32GB, this module is ideal for projects requiring reliable and expandable non-volatile data storage.
وحدة Micro SD Card Module هي وحدة تخزين مدمجة تتيح للمتـحكمات الدقيقة والأنظمة المدمجة قراءة وكتابة البيانات على بطاقات Micro SD وMicro SDHC بسهولة. تعتمد على واجهة الاتصال القياسية SPI مما يجعل دمجها مع منصات التطوير المختلفة مثل Arduino وESP32 وSTM32 أمرًا بسيطًا وسريعًا. تحتوي الوحدة على دائرة تحويل مستويات الجهد المدمجة، مما يسمح بالعمل مع أنظمة 3.3 فولت و5 فولت دون الحاجة إلى دوائر إضافية. تدعم بطاقات ذاكرة تصل إلى 32 جيجابايت، وتعد خيارًا مثاليًا لتسجيل البيانات، وتخزين الملفات، وتطبيقات إنترنت الأشياء والأنظمة المدمجة.
The Micro SD Card Module is a versatile storage interface module that allows microcontrollers and embedded systems to access files stored on Micro SD memory cards. The module communicates through the SPI (Serial Peripheral Interface) protocol, making it compatible with a wide range of development boards and microcontroller platforms.
An onboard voltage level conversion circuit enables safe operation with both 3.3V and 5V logic levels, eliminating the need for external level-shifting components. This makes the module suitable for Arduino boards, AVR microcontrollers, PIC systems, ESP32, STM32, and many other embedded platforms.
The module supports both standard Micro SD cards up to 2GB and Micro SDHC cards up to 32GB, providing flexible storage options for data logging, configuration storage, multimedia files, and sensor data collection.
Using available software libraries, developers can easily create, read, write, modify, and manage files directly from their applications. This makes the module an excellent solution for projects requiring reliable and removable data storage.
