Overview

The SparkFun BOB-00544 is a compact breakout board for microSD cards that converts the high-density surface mount pins of a microSD socket to a standard 0.1 inch pitch header. It features a push-push type socket for secure card retention and easy removal. This board allows engineers to quickly add mass storage to projects using a breadboard or through-hole prototyping area.

Why Choose This Part

This breakout simplifies hardware integration by providing a 7-position plated through-hole interface that is compatible with standard breadboards. The push-push mechanism ensures the card is physically locked in place, reducing the risk of accidental disconnection during operation.

Applications

Data Logging
Store large datasets from sensors or system logs onto standard microSD media in embedded systems.
Firmware Updates
Implement bootloaders that read new firmware images from a removable memory card.
Asset Storage
Host images, configuration files, or audio clips for user interface components in resource-constrained MCUs.

Key Specifications

Package Accepted microSD Card
Proto Board Type Connector to Plated Through Hole
Size / Dimension 0.850" L x 0.800" W (21.59mm x 20.32mm)
Number of Positions 7

Getting Started

Connect the breakout to an SPI-capable microcontroller using VCC, GND, MISO, MOSI, SCK, and CS pins. Ensure your system uses 3.3V logic as the board does not include level shifters; a voltage divider or logic level converter is required for 5V systems like the Arduino Uno.
