Efficient Storage Interface
This breakout board offers compact and reliable integration for SD card storage projects. It supports both SPI and SDIO interfaces, making it versatile for many microcontroller applications.
Designed exclusively for 3V systems, it provides an easy way to connect SD cards, which are inexpensive, durable, and widely available, perfect for storing images, logs, audio, and other data files.
Dual Protocol Compatibility
Unlike conventional SPI-only breakout boards, this model supports SDIO, a multi-pin data protocol that enables up to four data lines and higher clock speeds.
This allows significantly faster data transfer compared to SPI, which has only one data line, enhancing performance for demanding storage tasks.
- Supports SPI mode for basic SD card interfacing
- Enables SDIO mode for faster multi-pin data communication
- Ideal for controllers with SDIO hardware and firmware support
Designed for 3V Logic Controllers
The board does not include level shifting or power regulation circuits, making it suitable only for 3V logic and power supply systems.
Its bi-directional SDIO pins are optimized for lower voltage environments, and using it with 5V systems may damage the device or fail to operate.
- No built-in level shifters or voltage regulators
- Compatible only with 3V power and logic controllers
Compact and Breadboard Ready
Measuring just 25.4mm by 22.8mm, this breakout board is small and convenient for embedded projects.
It comes with header pins included, allowing easy insertion into breadboards for rapid prototyping and testing.
- Small form factor: 25.4mm x 22.8mm x 3.8mm
- Includes header pins for breadboard compatibility

Product FAQ
Frequently asked questions
01 What is the operating voltage of this breakout board?
This breakout board operates exclusively at 3 volts and is not compatible with 5V power or logic levels.
02 Can this breakout board be used with SPI communication?
Yes, it supports SPI mode communication through an SPI port and chip select pin.
03 Does this breakout board support SDIO interface?
Yes, unlike fixed SPI adapters, it supports SDIO hardware interface with up to 4 data pins for faster data transfer.
04 Is this breakout board compatible with all microcontrollers?
It's compatible only with 3V controllers that support SPI or SDIO communication protocols; 5V controllers are not supported.
05 Does the breakout board include built-in level shifters or power regulators?
No, this board does not have level shifters or power regulators; it requires a 3V power supply and logic.
06 What are the physical dimensions of the breakout board?
The board measures approximately 25.4mm x 22.8mm x 3.8mm in size.
07 Does this board include an SD card?
No, the SD card itself is not included with the breakout board.
08 Are header pins included for breadboard use?
Yes, the breakout board comes with header pins for easy integration into breadboards.
09 Will using SDIO improve data transfer speeds?
On controllers with SDIO support, it can offer faster data transfer speedsβup to approximately double compared to SPI mode.
10 What should I verify before using SDIO mode with this breakout board?
You should confirm that your controller supports SDIO protocol and that you have compatible SDIO firmware or libraries available.
