Product description: SPI Flash SD Card - XTSD 512MB - module with NAND Flash memory - Adafruit 4899
SPI Flash SD Card from Adafruit is a module that offers the functionality of an SD card in SMT chip format , with a built-in memory of 512 MB . With this device you can use SD libraries such as those available for Arduino and CircuitPython, making it easier to manage data without the need for physical SD cards. The module is ideal for applications where traditional SD cards may fall out or become damaged, such as in high vibration environments. It has a built-in NAND memory management mechanism that automatically takes care of wear leveling and error correction, eliminating the need to manually remove memory blocks. The SPI interface allows clock speeds of up to 50 MHz , which allows for fast and efficient writing and reading of data. The module supports both 3 V and 5 V voltages thanks to the built-in voltage converter . Just connect the SPI pins to your microcontroller and use your favorite SD library to get started quickly.
The manufacturer has prepared a detailed user guide that will help you start working with the module.
SPI Flash SD Card - XTSD 512MB - module with NAND Flash memory - Adafruit 4899.
Module with built-in memory with a capacity of 512 MB.
Special features of the module
- It has 512 MB of capacity, allowing you to store large amounts of data in a stable manner.
- Compatible with SD libraries for Arduino and CircuitPython, making it easy to integrate into existing projects.
- Built-in NAND memory management and error correction mechanism ensures stable and reliable operations.
- Support for clock speeds up to 50MHz and Class 8 write speeds enable fast data writing and reading operations.
- Possibility to work with boards powered by 3.3 V and 5 V thanks to the built-in voltage converter.
- It is suitable for recording data in devices exposed to strong vibrations, where there is a risk that the SD card will come loose.
- Compact size, suitable for space-saving projects.
Pinout description and connection diagram
The board has pins in the form of solder pads to which the goldpin strip included in the kit should be soldered. The module can also be connected using a breadboard and appropriate cables - without the need for soldering. Individual pins should be connected according to the following relationships:
- VIN - 5V power pin
- 3V3 - 3.3 V power pin
- GND - system ground
- SCK - SPI bus clock line
- MISO - SPI bus input data line
- MOSI - SPI bus output data line
- CS - Chip Select for SPI
The SPI Flash SD card is not intended to be directly connected to a computer and used as storage like a micro SD card. We suggest using a regular SD card for such applications.
