Key features and benefits - Simple powered operation - The device uses a 5V power supply. Normal operating voltage is 5V ± 0.25V, and current consumption is less than 200 mA. - The POWER power supply socket can be powered by a standard 5V source, such as a hard disk supply. - IDE interface compatibility - Uses an 80-pin IDE connection. Compatible with standard IDE cables that use 80-pin data interfaces. - Supports PIO, Multi-Word DMA, and Ultra DMA host transfer modes for flexible data transfer performance. - SD storage support - The SD socket accepts SD cards up to 128 GB. - Plug-and-play drive behavior - When powered, connected to an IDE cable, and with an SD card inserted, the board presents itself to the host as an electronic hard disk. - No driver installation is required. - After the operating system is installed, the system can be started from the SD memory card (for example, via Windows 98 and similar OS). Use scenarios - Retro and legacy PC upgrades - Bring modern SD storage to older IDE-based systems. Install an operating system on the SD card and boot directly from it without additional drivers. - Embedded or compact systems - Use the SD card as the boot drive for small form factor or embedded projects that rely on IDE interfaces, reducing moving parts and power consumption. - Data preservation and legacy storage - Replace traditional hard drives in compatible systems with the SD-based solution to improve reliability and simplify upgrades, while maintaining full IDE compatibility. Technical specifics at a glance - Power: 5V supply; voltage tolerance 5V ± 0.25V; current < 200 mA. - Interface: IDE with 80-pin cable; supports PIO, Multi-Word DMA, Ultra DMA host modes. - SD capacity: Up to 128 GB SD cards. - Operation: No driver installation required; enables booting operating systems from SD after installation.
