The MB85RC256V FRAM Breakout Module is a high-performance, non-volatile memory board that combines the speed of SRAM with the data retention capability of Flash. Unlike EEPROM or Flash memory, FRAM (Ferroelectric RAM) offers extremely high endurance—supporting up to 10 trillion read/write cycles—making it ideal for data logging, sensor recording, and...

The Micro SD Card Breakout Board is designed for connecting micro SD memory cards to 3.3V microcontrollers for data storage and retrieval. It supports both SPI and SDIO communication modes, allowing flexibility between simple wiring using SPI or higher speed data transfer using SDIO where supported.

The MCP4728 is a versatile quad-channel 12-bit digital-to-analog converter (DAC) with built-in EEPROM, allowing all four output voltages to be saved and automatically restored on power-up. This makes it ideal for applications where stable, predefined analog voltages are required immediately after startup.

The 24LC32 I²C EEPROM module is a compact non-volatile memory board based on the Microchip 24LC32 chip, providing 32Kbit (4KB) of EEPROM storage.This version features STEMMA QT / Qwiic connectors, allowing solder-free plug-and-play connection using standard JST-SH cables.

The OpenLog Blackbox is a compact serial data logger designed to record large amounts of data directly to a microSD card using a simple UART interface. It is widely used as a blackbox flight data logger for Cleanflight, Betaflight, Naze32, F3/F4 flight controllers, and general microcontroller projects.
