Soldered microSD Card Reader Breakout
Overview
A small breakout board that provides a microSD card socket and accessible signal/power pins for prototyping. It lets you add removable flash storage to microcontroller and single-board-computer projects without dealing with the tiny surface-mount connector. The board is intended for easy soldering or header attachment for use on breadboards or perf boards.
Why Choose This Part
Breakout boards like this turn the small microSD connector into easy-to-access pins so you can wire a card into your project without SMT work. They are low-cost, compact, and intended for quick evaluation or integration into prototypes. The labeled breakout makes wiring to common microcontroller pins straightforward and saves time compared with designing a PCB footprint for the connector.
Applications
Getting Started
Connect the breakout to your MCU or development board following the card-power and signal pins (microSD cards require 3.3V). Most microcontrollers access cards over SPI using the Arduino SD library or FatFs on RTOS/embedded toolchains; single-board computers can use their SD interfaces and drivers. Ensure you supply the correct voltage level and use a common ground; on 5V boards you will need level shifting or a 3.3V supply for the card.
