Micro SD Card Module (SPI) for Arduino / Raspberry Pi – 3.3V Regulator, 5V Compatible

Micro SD Card Module (SPI) – a compact breakout board that lets you add Micro‑SD storage to Arduino, ESP, STM32, Raspberry Pi and other microcontrollers using the standard SPI interface.

Key Features

• SPI Interface: Uses MOSI / MISO / SCK / CS pins for easy integration.
• 5V Compatible Input: On‑board level shifting + regulation for safe use with 5V logic boards (module outputs 3.3V signals to the card).
• On‑board 3.3V Regulator: Stable power for the Micro‑SD card.
• Micro‑SD Socket: Supports standard Micro‑SD / Micro‑SDHC cards (FAT/FAT32 depending on your controller/library).
• Header Pins Included: Easy breadboard/prototyping connection.

Typical Pinout

• VCC (5V or 3.3V depending on board version)
• GND
• MISO
• MOSI
• SCK
• CS (Chip Select)

Applications

• Data logging (sensors, weather stations, IoT)
• Audio / media file storage
• Configuration & firmware file hosting
• DIY projects and robotics

Package Includes: 1× Micro SD Card Module (SPI). Micro‑SD card not included.
