Product description: SPI Flash SD Card - XTSD 2 GB - module with NAND Flash memory - Adafruit 6038
The Adafruit SPI Flash SD Card - XTSD 2GB is a groundbreaking storage module that combines the advantages of a traditional SD card with an SMT form factor . Despite its appearance similar to SPI Flash chips, this module functions like a full- fledged 2GB SD card with a FAT file system. It's ready for use with popular SD libraries for Arduino and CircuitPython , making it an exceptionally convenient solution for builders and hobbyists. With support for up to 50MHz, Class 8 storage , and built-in ECC and wear leveling , the module ensures high reliability and stability.
The manufacturer has prepared a detailed user guide that will help you start working with the module.
SPI Flash SD Card - XTSD 2 GB - module with NAND Flash memory - Adafruit 6038.
This module works like a full-fledged 2 GB SD card.
Main features of the module
- SD card emulation in SMT format : the device behaves like a classic SD card with an SPI interface
- Compatibility with Arduino IDE and CircuitPython libraries : supported via standard SD libraries
- 3V and 5V support : built-in logic level converters and 3.3V regulator
- Ready to use : factory formatted with FAT
- High vibration resistance : ideal for applications in demanding conditions
- ECC and wear leveling : automatic error and memory wear management
- Class 8 Write Speed : Fast and reliable write operations
- Clock speed up to 50 MHz : fast communication with the microcontroller
Pinout and SPI interface
The Adafruit XTSD 2GB module offers a standard set of pins for SPI:
- VIN : module power supply (3 V to 5 V)
- 3V3 : output from built-in regulator (up to 100 mA)
- GND : ground
- SCK : SPI clock (input)
- MISO : data from module to microcontroller
- MOSI : data from microcontroller to module
- CS : system selection - activation by a low logic state
Compatibility and programming
The module is fully compatible with popular development platforms such as Arduino , Adafruit Feather , Metro , and other SPI-based microcontrollers . It is supported via the classic SD (for Arduino) and adafruit_sdcard (for CircuitPython) libraries. This allows for easy implementation of file read and write operations. When combined with microcontrollers offering USB mass storage access, the module can act as a reliable data carrier . Due to the lack of a traditional SD connector, the module is not intended for direct use with computers – its primary use is in embedded projects.
The module supports voltages of 3 V and 5 V.
