Sparkfun - MicroDrive: Module for microSD /
FAT filesystem over TTL UART The µDRIVE-uSD-G1 is an
extremely compact and easy to use FAT data storage/logger device that uses
simple TTL serial commands for configuration and data read/write. It can easily interface to any
microcontroller that requires a Disk Drive data storage system. Most
microcontrollers are limited by the available onboard memory for those
applications that require large volumes of data. The µDRIVE-uSD-G1 takes that
burden away from the host controller by allowing data transfers to-and-from via
a simple serial interface.
A handful of straightforward commands provide direct
access to the onboard micro-SD memory card for storing
and retrieving any size or type of binary data or
perform FAT file access (Read, Write, Dir, Erase and Initialize supported).
Applications can range from Data Logging, Program
Storage, Music files, Image files, Video Clips or any
general purpose data storage.
Features:
- Onboard micro-SD (µSD) memory card adapter
that can accommodate 64Mb to 2Gig memory cards
- Simplified commands provide read and write
access to 512 byte sectors
- Supports FAT filesystems and Direct Access
(sector by sector)
- FAT directives supported: Read, Write,
Erase, Dir and Initialize
- Easy 5 pin interface to any host device: VCC,
TX, RX, GND, RESET
- Green LED: Power and Memory Card detect
indicator
- Red LED: Disk Drive data access indicator
- Wide supply voltage range from 3.6-6V
- 23mA nominal when using a 5V supply
- Powered by the 4D-LABS GOLDELOX processor
