1.1 x Riser Card PCIe to Dual TF Card (MR14) Key benefits Adds flexible, lowcost removable storage to notebooks and small systems by converting a halfheight mini PCIe slot into a dual TF (microSD) card interface. Enables use of microSD cards as SSD/ReadyBoost storage for quick expansion or caching without replacing internal drives. Simplifies installation and daily use: insert TF cards into the half‑height mini card slot and access them like standard removable drives. Primary features Form factor: mini PCIe riser card that supports dual TF (microSD) cards; compatible with MicroSDXC, SDHC and SD formats. Material: durable PC + metal construction for reliable mechanical and thermal performance. Integrated MR14 controller: functions as a card reader and flash card controller with a builtin DMA hardware engine for efficient data movement. Onboard voltage regulation: supports 5V → 3.3V and 3.3V → 1.8V conversions to meet card and system power requirements. USB mass storage and fast transfer support: MR14 provides standard USB massstorage behavior and accelerated transfer functions where supported by host and media. Compatibility and performance notes Intended for installation into half‑height mini PCIe card slots commonly found in notebooks and embedded systems. Supports microSD cards in SDXC/SDHC/SD formats; performance depends on card class, host interface, and system configuration. MR14's DMA engine improves transfer efficiency and reduces CPU overhead during sustained transfers. Practical applications Expand notebook storage: add removable microSDbased storage to laptops with half‑height mini PCIe slots for photos, media, and documents without opening the main drive bay. SSD/ReadyBoost caching: use ‑endurance microSD cards as additional cache or ReadyBoost storage to improve responsiveness on systems with limited internal SSD capacity. Fast data exchange: rapidly move large files between devices by using TF cards with MR14's USB mass storage and fast transfer support. What to expect in use Simple operation: plug TF cards into the MR14equipped mini card slot; the host recognizes the cards via the MR14 controller. Reliability depends on card quality: choose appropriate microSD cards (speed and endurance) for sustained or cachelike workloads. No additional software typically required for standard USB massstorage functionality; driver support for MR14 features depends on the host OS.
