That makes them perfect for microcontroller storage and retrieval - whether it's images, fonts, GIFs, audio files, or sensor logs.\u003c\/p\u003e\n\u003cp\u003eWiring up SD cards when you're starting out is super easy - you just \u003ca href=\"\/en-eu\/products\/adafruit-microsd-card-breakout-board\" target=\"_blank\" rel=\"noopener noreferrer\"\u003epick up one of these SPI-to-SD breakout boards\u003c\/a\u003e, \u003ca href=\"https:\/\/learn.adafruit.com\/adafruit-micro-sd-breakout-board-card-tutorial\" target=\"_blank\" rel=\"noopener noreferrer\"\u003ewire it to an SPI port and a chip select pin and with a little library work you're reading and writing files\u003c\/a\u003e. That's all good and great but you may eventually find that your SD card project is a little...slow. \u003cstrong\u003eEven with fast SPI ports, there's only one data pin, which can make it hard to stream large files fast.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIf you've hit that limit, this breakout is designed to help - unlike the other adapter, it is not fixed for SPI usage, and can be used with SDIO hardware support. SDIO is a multi-pin data protocol (up to 4 data pins at once!) SDIO also tends to be able to be clocked faster than SPI. Of course, your speeds will vary depending on what microcontroller you hook it up to. When Adafruit used SDIO instead of SPI on CircuitPython with the \u003ca href=\"\/en-eu\/products\/adafruit-grand-central-m4-express-featuring-samd51-without-headers\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSAMD51 Grand Central\u003c\/a\u003e, they got a speed increase of about double when reading data off the card.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eYou will need to verify that your microntroller has SDIO support and you have SDIO firmware\/library support as wel\u003c\/strong\u003el. SDIO is usually available on higher end chips, and you may need to use a specific pin set. You can \u003cem\u003estill\u003c\/em\u003e use this for SPI mode, but it does not have level shifters so it's not for use with 5V microcontrollers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFor use with 3V power and logic microcontollers only! \u003c\/strong\u003eThe SDIO pins are bi-directional, and we've never seen a 5V microcontroller with SDIO, so there's no level shifting or power regulator.\u003c\/p\u003e\n\u003cp\u003eComes with a bit of header so you can use in a breadboard.\u003cstrong\u003e Doesn't come with the micro SD card itself!\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Dimensions: 25.4mm x 22.8mm x 3.5mm \/ 1.0\" x 0.9\" x 0.1\"\u003c\/li\u003e\n\u003cli\u003eProduct Weight: 2.5g \/ 0.1oz\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":32107008131155,"sku":"ADA4682","price":3.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/4682-01.jpg?v=1596641507","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/adafruit-micro-sd-spi-or-sdio-card-breakout-board-3v-only","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
