Unlike SPI-only breakouts, this board exposes the full SDIO bus with up to 4 data pins for significantly faster read/write speeds — roughly double the throughput compared to SPI on supported microcontrollers. SDIO is ideal for projects that need to stream large files quickly, such as audio playback, video display, or high-frequency data logging. You can still use this board in SPI mode for simpler setups. Note that this board operates at 3.3V only — there are no level shifters or voltage regulators on board. Key Features SPI + SDIO Support – Use standard SPI or faster multi-pin SDIO protocol Up to 4 Data Pins – SDIO mode provides significantly faster throughput than single-pin SPI MicroSD Card Slot – Standard push-push socket for microSD cards 3.3V Operation – Direct connection to 3.3V microcontrollers Breadboard Friendly – Includes header for easy prototyping Compact Breakout – Minimal footprint for embedding in projects Ideal For High-speed data logging requiring fast write speeds Audio and video file streaming from microSD Projects that have outgrown SPI-only SD card speeds CircuitPython and Arduino projects on SDIO-capable microcontrollers Package Contents 1× Adafruit Micro SD SPI/SDIO Breakout Board 1× Header pin strip Warning: For use with 3.3V power and logic microcontrollers only! There is no level shifting or power regulation on this board. Not compatible with 5V microcontrollers. MicroSD card not included. Note: SDIO mode requires microcontroller hardware support and compatible firmware/library. Verify your microcontroller supports SDIO before purchasing for that purpose. SPI mode works with any SPI-capable 3.3V microcontroller.
