The MicroSD card is the hard drive of your Raspberry Pi. A slow or generic card can cause system lag, corrupted data, or boot failures. SunFounder selects only authentic, high-speed Raspberry Pi SD cards (UHS-I / Class 10) tested for random I/O performance. This ensures your operating system loads quickly, and applications run smoothly, whether you are running a retro gaming console or a home automation server.
○ Pre-loaded SD Cards: Perfect for beginners. These cards come with the Raspberry Pi OS installer pre-flashed. Just insert the card, power on, and follow the simple on-screen instructions to set up your desktop.
○ Blank MicroSD Cards: Ideal for advanced users who want to install specific operating systems like Ubuntu, RetroPie, or Home Assistant manually using the Raspberry Pi Imager.
○ What size SD card do I need?
For most beginners and standard projects, a 32GB MicroSD card is the sweet spot, offering plenty of room for the OS and apps. If you plan to store media files or run heavy databases, we recommend upgrading to 64GB or 128GB.
○ Will these cards work with Raspberry Pi 5?
Yes, our Raspberry Pi SD cards are fully compatible with the new Raspberry Pi 5, as well as older models like the Pi 4 Model B and Pi 3.
○ Do I need an SD card reader?
If you buy a blank card, you will need a USB card reader (often sold separately or in our bundles) to flash the OS from your computer. Our pre-loaded cards save you this step.
