Dual MicroSD to Mini PCIe adapter

The EVESKY MR14 converts an internal Mini PCI Express slot into two MicroSD card slots for laptop users who want low-cost solid-state storage or a ReadyBoost cache without opening the drive bay. It accepts standard TF cards and presents them to the system through the host Mini PCIe interface.

Installation and common issues

Insert each MicroSD card until it clicks, then secure the board with the laptop’s Mini PCIe retention screw; no drivers are required for basic mass-storage access. The most frequent problem is a card not seating fully, which the BIOS then fails to enumerate.

Before ordering

Verify the laptop exposes a full-size Mini PCI Express slot that is not wired exclusively for Wi-Fi or WWAN, and confirm the BIOS supports booting or caching from a mass-storage device on that slot. The adapter regulates 5 V to 3.3 V and 1.8 V internally, so no external power connection is needed.

Questions about this item

How do I confirm the MR14 is working after installing two MicroSD cards?

The adapter appears as two separate storage volumes in the operating system and the laptop recognises both cards without driver installation.

What comes in the box and what must I supply?

The MR14 board is included; you must provide up to two MicroSD cards and a laptop with a free Mini PCIe slot.

Which version of the MR14 should I choose for 1.8 V and 3.3 V cards?

This single model regulates 5 V to 3.3 V and 3.3 V to 1.8 V, so it supports both voltage families without a separate version.
