Fermion: SD Card Module (Breakout, SPI)

The Fermion SD Card Module is a compact breakout board designed to add removable flash memory storage to microcontroller projects via an SPI interface. It supports both standard SD and Micro SD (TF) cards, making it an ideal data expansion solution for students, hobbyists, and robotics engineers. Directly compatible with Arduino shield layouts and other SPI-capable development boards, it simplifies sensor data logging and file transfers.

High-capacity data logging

This module significantly expands embedded storage capacity compared to the limited onboard memory found on standard microcontrollers. It enables efficient collection, buffering, and retrieval of runtime data, experiment records, and system diagnostics.

Dual SD and TF card support

The breakout board accommodates both standard SD cards and Micro SD (TF) cards for flexible memory media selection. Removable flash storage allows seamless file access and easy data transfer between embedded hardware and desktop computers.

SPI communication and board compatibility

Equipped with an SPI communication interface, the board connects directly to Arduino shield pinouts as well as other SPI-capable microcontroller platforms. Its modular form factor enables rapid prototyping and straightforward wiring in experimental electronics setups.

Versatile embedded applications

This storage interface supports applications requiring persistent data collection, such as IoT environmental monitoring, robotics telemetry recording, portable measurement instruments, and STEM education projects.

Package contents

The package includes one SD card module breakout board ready for embedded storage and logging projects.
