MicroSD Card Module with Level Shifter — SPI, 3.3V / 5V

MicroSD Card Module with Level Shifter — SPI, 3.3V / 5V

A MicroSD card module with built-in level shifter for safe operation with both 3.3V and 5V Arduino boards. The integrated level shifter converts 5V SPI signals to 3.3V for the SD card, preventing damage from overvoltage. Supports FAT16 and FAT32 formatted MicroSD cards up to 32GB via the Arduino SD library.

Key Specifications
