Pololu microSD Card Breakout Board
Overview
The Pololu 2587 is a compact breakout board for microSD cards that converts the dense surface-mount microSD socket pins to a standard 0.100 inch (2.54mm) pitch. It features an integrated level shifter and a 3.3V voltage regulator, allowing it to interface safely with 5V systems like many Arduino boards.
Why Choose This Part
This module simplifies the integration of microSD storage by handling the necessary logic level shifting between 5V and 3.3V automatically. The 0.100 inch header spacing makes it directly compatible with standard breadboards and perforated prototyping boards.
Applications
Getting Started
Connect the SPI interface pins (MOSI, MISO, SCK, and CS) to your microcontroller and provide power to the VDD pin. When using with the Arduino IDE, the standard SD library can be used by specifying the appropriate Chip Select (CS) pin in the SD.begin() function.
Also Consider
