Description
Breaks out the pins of a microSD card connector
Can be directly integrated into 5 V systems
On board 3.3 V regulator and level shifting circuity
0.1″ pin spacing allows compatibility with standard perfboards
The Breakout Board for microSD Card w/ 3.3V Regulator and Level Shifters breaks out the pins of a microSD card connector necessary to interface with the card through SPI (Serial Peripheral Interface), and it can be directly integrated into 5 V systems thanks to its on board 3.3 V regulator and level shifting circuity. The 0.1″ pin spacing allows compatibility with standard perfboards, solderless breadboards, and 0.1" connectors.
Level-shifted uSD adapter that works with other SPI devices
The Pololu uSD breakout has an onboard 3v3 regulator and level shifters. The DO/MISO signal is tri-state controlled by the CS signal, so this breakout does not interfere with other SPI devices. (Most other breakouts don't do this.) Like Pololu's other modules, this is well-made and well-documented. RobotShop carries many of Pololu's modules and their prices are great.
