MicroSD Breakout Board
Overview
The Boardoza MicroSD Breakout Board is a high-performance, industrial-grade storage expansion module engineered for reliable non-volatile data management in embedded environments. Designed to provide a seamless bridge between microcontrollers and high-capacity flash media, this board simplifies the integration of external storage via the robust SPI (Serial Peripheral Interface) protocol.
Engineered for high data integrity and durability, it serves as the primary storage backbone for high-frequency data logging, local firmware repositories, and multimedia asset hosting in complex IoT ecosystems.

Mechanical and Pinout Interface
Key Engineering Features
Enhanced Signal Integrity
The Boardoza MicroSD Breakout is designed with high-frequency signal propagation in mind. The PCB layout features optimized trace routing and onboard de-coupling capacitors to mitigate power-line noise and electromagnetic interference (EMI), ensuring stable communication even at high SPI clock speeds.
Seamless SPI Integration
The module simplifies the complex SD physical layer into a standard 6-pin SPI interface. This allows for rapid deployment across various architectures including ARM Cortex-M, AVR, ESP32, and RISC-V. By handling the mechanical and electrical interface of the microSD slot, it allows engineers to focus on high-level file system implementation.
Industrial Durability & Compactness
Constructed with a high-quality push-pull microSD socket, the board is built to withstand repeated insertion cycles. Its small form factor makes it ideal for space-constrained applications such as wearable diagnostics or compact industrial controllers where internal MCU flash is insufficient.
Applications
Black-Box Logging: High-resolution recording of flight data, vehicle telemetry, or industrial sensor arrays for post-mortem analysis.
Firmware Staging (FOTA): Serving as a local buffer for Over-The-Air firmware updates before system flashing.
Multimedia Repositories: Local storage for high-resolution GUI bitmaps, WAV audio files, or complex configuration scripts.
Offline Data Collection: Long-term environmental monitoring in remote areas where cloud connectivity is intermittent.
Empower your embedded system with reliable, high-capacity storage using the Boardoza MicroSD Breakout Board.
Bit Order: MSB (Most Significant Bit) First.
