Arduino Compatible SD Card Interface Module – Jaycar XC4386

You're logging sensor data or storing project files and the last thing you need is a fried IO pin because the voltage didn't match. This module takes care of that for you. Built-in resistors let it safely accept either 5V or 3.3V from your Arduino's IO pins, so you don't have to second-guess the wiring. Push-pull SD card socket, FAT16 and FAT32 support out of the box, and it works with the libraries already bundled in your Arduino IDE. No extra shield. No breakout board. Just slot your card and write

• 5V and 3.3V power inputs with built-in resistors for safe IO pin connection
• Push-pull style SD card socket for reliable card seating
• Supports FAT16 and FAT32 formats using inbuilt Arduino libraries
• Compatible with standard Arduino development boards
• Priced at $5.29 — a fraction of the $16.30 RRP
