Micro SD Card Reader Module

Micro SD Card Reader Module for Arduino provides a reliable way to add storage capability to your Arduino and other microcontroller projects. This module supports standard Micro SD and TF cards, enabling you to log data, store files, or load resources directly from removable storage.

Key Features:

• Wide Compatibility: Works seamlessly with Arduino, ESP8266, ESP32, and other microcontrollers.
• SPI Interface: Uses standard Serial Peripheral Interface for fast and stable communication.
• Card Support: Reads and writes standard Micro SD and TF cards (FAT16/FAT32 formats).
• Integrated Level Shifter: Accepts 3.3 V and 5 V logic levels.
• Plug-and-Play: Ready for direct integration into breadboard or PCB designs.

Technical Specifications:

• Operating Voltage: 3.3 V to 5 V DC
• Interface: SPI (MISO, MOSI, SCK, CS)
• Supported Card Types: Micro SD, TF (up to 32 GB)
• File System Support: FAT16, FAT32
• Logic Level: 3.3 V (with onboard level shifting)

Mechanical Specifications:

• PCB Material: FR-4 epoxy laminate
• Card Slot: Spring-loaded Micro SD slot
• Connector Type: 6-pin male header

Dimensions:

• Module Size: Approx. 42 mm × 24 mm
• Header Pitch: 2.54 mm
• Weight: ~5 g

Pinout and Wiring:

• VCC: Power input (3.3 V–5 V)
• GND: Ground
• MISO: Master In Slave Out
• MOSI: Master Out Slave In
