Description

StarTech SDMSDRWU3AC USB-C/A Multi-Card Reader

Overview

The StarTech SDMSDRWU3AC is a compact, USB-powered multi-card reader designed to provide access to SD/MMC and microSD flash memory cards on modern devices. It bridges the gap for systems that may lack integrated card slots, enabling rapid data transfer up to 5Gbps. This device is ideal for quickly offloading footage from surveillance cameras, drones, or other devices that record to common flash media, directly to a laptop, tablet, or workstation equipped with USB-C or USB-A ports. Its small form factor makes it suitable for mobile kits or desktop setups where space is at a premium.

Compatibility

This reader is compatible with any host device featuring a USB-C or USB-A port and supporting USB 3.2 Gen 1 (5Gbps) or higher. It supports standard SD, SDHC, SDXC, and MMC memory card formats, as well as microSD, microSDHC, and microSDXC formats. The reader is designed to work with card capacities up to 2TB, ensuring compatibility with the largest available flash media. It functions as a standard Mass Storage Class device, requiring no special drivers on most modern operating systems (Windows, macOS, Linux).

Installation Notes

The SDMSDRWU3AC is USB-powered, drawing 5V DC directly from the host port. No external power adapter is required. Its operating temperature range is 0°C to 75°C (32°F to 167°F), and storage temperature is -20°C to 70°C (-4°F to 158°F). It operates within a humidity range of 50% to 90% RH (non-condensing).
