Adafruit Micro SD SPI or SDIO Card Breakout Board - 3V ONLY!

Key Features Perfect for microcontroller storage and retrieval - whether it's images, fonts, GIFs, audio files, or sensor logs Multi-pin data protocol (up to 4 data pins at once!) Not fixed for SPI usage Can be used with SDIO hardware support - clocked faster that SPI Micro SD cards and microcontrollers go together like micro-peanutbutter-and-jelly: SD cards are inexpensive, durable, easy to find at any shop, come in many sizes and can plug into any computer using a common SD card reader. That makes them perfect for microcontroller storage and retrieval - whether it's images, fonts, GIFs, audio files, or sensor logs.Wiring up SD cards when you're starting out is super easy - you just pick up one of Adafruit SPI-to-SD breakout boards, wire it to an SPI port and a chip select pin and with a little library work you're reading and writing files. That's all good and great but you may eventually find that your SD card project is a little...slow. Even with fast SPI ports, there's only one dat
