Adafruit MicroSD card breakout board+

This microSD adapter is not just a simple breakout board; it's engineered for superior convenience and performance. Equipped with an onboard 5V to 3V regulator, it delivers 150mA for power-demanding cards, and its 3V level shifting allows effortless compatibility with both 3V and 5V setups.

Using a genuine level shifting chip instead of resistors ensures minimized issues and enhanced read/write speeds. With the capability to use just 3 or 4 digital pins, you can easily manage more than 2Gb of storage. An activity LED provides real-time status updates, lighting up whenever the SD card is being accessed.

The push-push socket design slightly protrudes the card for easy insertion and removal. It includes four #2 mounting holes and comes with a 0.1" header (unattached) so you have the flexibility to use it on a breadboard or with wires.

This adapter is thoroughly tested and assembled at the Adafruit factory, ensuring optimal performance. It's fully compatible with Arduino, complete with abundant example code and wiring diagrams. For a seamless Arduino setup: connect GND to ground, 5V to 5V, CLK to pin 13, DO to pin 12, DI to pin 11, and CS to pin 10, then deploy the SD library for full support of FAT and FAT32 SD cards. Detailed tutorials are available to guide you through microSD cards, wiring, and utilizing this breakout board with an Arduino or CircuitPython.
