Micro SD Card Reader Module

Micro SD Card Reader Module – Seamless Storage for DIY Electronics

The Micro SD Card Reader Module makes it easy to add removable storage to microcontroller and single-board computer projects. Designed for simplicity and reliability, this module supports SPI communication and standard microSD cards formatted as FAT16 or FAT32. Use it for data logging, media playback, sensor recording, and offline storage without relying on cloud services.

Key Features

• High-speed SPI interface for responsive reads and writes during real-time logging.
• Broad compatibility with Arduino, Raspberry Pi, ESP8266, ESP32 and most microcontrollers that support SPI.
• microSD support using standard FAT16 and FAT32 file systems (up to 32GB).
• Wide input voltage from 3.3V to 5V for direct connection to common development boards.
• Compact form factor ideal for embedded systems, wearable projects, and space-constrained enclosures.
• Plug-and-play integration with standard libraries and abundant tutorials.

Product Specifications

• Input Voltage: 3.3V to 5V
• Interface: SPI
• Card Format: microSD (FAT16 / FAT32)
• Maximum Supported Capacity: 32GB
• Dimensions: 42 mm x 24 mm
• Operating Temperature: -25°C to 85°C

Compatibility and Use Cases

This micro SD card reader module is ideal for a wide range of projects:

• Data logging with Arduino (temperature, humidity, GPS, etc.)
• Sensor recording and backups on Raspberry Pi
• Offline media storage for portable players
• Industrial logging systems and embedded storage
• Wireless remote storage solutions with ESP8266 and ESP32

Wiring and Library Recommendations

Typical Arduino Wiring (SPI)

• MOSI -> MOSI (Arduino pin 11 on UNO)
• MISO -> MISO (Arduino pin 12 on UNO)
• SCK -> SCK (Arduino pin 13 on UNO)
• CS -> Any digital pin (commonly pin 10)
• VCC -> 3.3V or 5V (module supports 3.3V-5V)
• GND -> GND

Raspberry Pi Wiring (SPI)

• MOSI -> MOSI (GPIO 10)
• MISO -> MISO (GPIO 9)
• SCK -> SCLK (GPIO 11)
• CS -> CE0 or a free GPIO
• VCC -> 3.3V
• GND -> GND

Software libraries: use the Arduino SD.h and SPI.h libraries, or the Linux SPI and FAT drivers on Raspberry Pi. For ESP8266 / ESP32 use the respective SD library and SPI settings in the board’s SDK.

How This Module Improves Your Workflow

Local logging with a Micro SD Card Reader Module eliminates reliance on Wi-Fi or cloud connectivity. Record sensor data, keep event logs, or store media files directly on a microSD card. This ensures uninterrupted data capture even in remote or offline deployments in Islamabad, Lahore, Karachi and other locations across Pakistan.

Common Questions

• Is this module compatible with Arduino UNO and Mega? Yes. It uses the SPI interface and works with both boards.
• Can I use this with Raspberry Pi? Yes. It connects through the Pi’s SPI pins and is compatible with most Pi models.
• Does it support high-speed data logging? Yes. The SPI interface and support for microSD FAT16/FAT32 cards up to 32GB allow smooth logging for most hobby and industrial use cases.
