With SD and MMC memory prices dropping, the time is right for mass storage and datalogging. The board does the 3.3V to 5V translatio so you can plug directly into Arduino. Using SD card with Arduino is easy too as long as we use the "slow" mode (via SPI and without interrupts) and only read/write single sectors (no "burst" modes).
