The Adafruit MicroSD card breakout board will let your next project store up to 2Gbytes of data using just 4 x pins on your microcontroller. Its onboard 5V to 3V regulator means it can supply up to 150mA to demanding SD cards. The board is 3 or 5V compatible and the level shifting has been done with a chip which makes it more reliable and allows faster read/write access. Adafruit have a free tutorial on all things micro-SD. Supplied as a fully assembled board plus a 1 x 8-pin 0.1in. pitch male header strip for you to solder in as required. * Supports FAT and FAT32 cards up to 2Gbytes * Level shifter for 3 to 5V compatibility * Uses 3 or 4 digital IO lines * Dimensions 31.85 x 25.4 x 3.75mm (1.25 x 1.00 x 0.15in.) * Adafruit part no. 254 *Customers looking to resell on eBay or Amazon should contact Adafruit directly. https://elecena.pl/product/27279008/adafruit-254-microsd-card-breakout-board 2024-11-14 https://elecena.pl/product/27279008/adafruit-254-microsd-card-breakout-board 2025-06-17 https://elecena.pl/product/27279008/adafruit-254-microsd-card-breakout-board 2025-08-15 https://elecena.pl/product/27279008/adafruit-254-microsd-card-breakout-board 2025-09-25 https://elecena.pl/product/27279008/adafruit-254-microsd-card-breakout-board 2026-03-25 https://elecena.pl/product/27279008/adafruit-254-microsd-card-breakout-board 2026-05-11 https://elecena.pl/product/27279008/adafruit-254-microsd-card-breakout-board 2026-07-18 https://elecena.pl/product/27279008/adafruit-254-microsd-card-breakout-board 2026-08-10
