Micro SD SDHC TF Card Adapter Logic Module with SPI Interface

The Micro SD SDHC TF Card Adapter Module is a compact breakout board that lets microcontrollers like Arduino or Raspberry Pi read and write to Micro SD and Micro SDHC memory cards via a standard SPI communication bus.

Key Features

• Card Support: Works with Micro SD (<2GB) and Micro SDHC (<32GB) memory cards formatted in FAT16 or FAT32
• Voltage Regulation: Features an onboard 3.3V Low Dropout (LDO) regulator to power the micro SD card safely.
• Level Shifting: Includes an active level-conversion circuit or chip, allowing safe data transfer with both 5V and 3.3V logic microcontrollers.
• Communication: Utilizes a standard 4-wire Serial Peripheral Interface (SPI). 

Pinout Configuration

• GND: Ground reference
• VCC / 5V: Power supply input (4.5V to 5.5V DC)
• MISO: Master In Slave Out (Data output from module)
• MOSI: Master Out Slave In (Data input to module)
• SCK / CLK: Serial Clock for synchronization
• CS: Chip Select (Enables or disables the module)
