Data Storage Module

Compact data logging module on microSD card, ideal for sensor logging and Blackbox on drones or embedded systems. Based on ATmega328 at 16 MHz, communicates via UART TTL with configurable speeds from 2400-115200 bps set in CONFIG.TXT, operates at 3-12 V with low power consumption for battery operation, supports cards up to 64GB FAT16/FAT32, and provides status LEDs for writing.

Adapter for testing and debugging SPI communication between microSD card and microcontroller, allows real-time sniffing and signal visualization with logic analyzer or oscilloscope. It has a standard microSD socket and connector that plugs directly into the port, plus 2.54mm breakout pins for quick access to CLK, CMD, DAT0, VCC and GND on breadboard or test leads. Ideal for rapid development and diagnostics.

Allows quick addition of microSD card storage for Wemos D1 Mini projects, ideal for data logging, files or updates. Communicates via SPI for efficient transfer, operates at 3.3V, supports Micro SD and Micro SDHC up to 32GB, compatible with FAT16/FAT32 file systems and Arduino SD or SdFat libraries.

Arduino compatible module for reading and writing to MicroSD and MicroSDHC cards, ideal for data logging and file storage in embedded projects. Communicates via SPI interface for fast integration, is powered at 5V on VCC and includes 3.3V regulator, has 6 pins GND, VCC, MISO, MOSI, SCK, CS, plus 4 M2 mounting holes for stable mounting.

The AT24C256 EEPROM module provides non-volatile memory for storing settings and data in microcontroller projects. It communicates quickly via a two-pin I2C interface, has a capacity of 256 Kb, operates at common 3.3V or 5V voltages, is compatible with the AT24CXX family, and is easy to integrate on breadboards or in prototypes.

Easily expands memory for Arduino projects, ideal when the EEPROM in the ATmega is no longer sufficient. Stores data permanently even without power, communicates quickly via I2C, offers 256Kbit 32KB capacity, operates at 1.8-5V and allows easy replacement of the AT24C256 chip for maintenance or upgrade.

Allows reading and writing data to SD card directly from Arduino projects, ideal for logging, storing configurations or files. Communicates quickly via SPI interface, supports SD and SDHC cards, is powered at 5V on VCC with integrated 3.3V regulator for compatibility, has 6 essential pins and 4 M2 mounting holes for secure mounting.
