Description
Expand Your M.2 B+M Key Slot with Storage or WWAN Support
The ACM2BM-2E1-2 allows devices with M.2 E Key or A-E Key interface (typically used for Wi-Fi, and other wireless modules with PCle signal) to be connected to a host wth an M.2 B/M Key slot (typically used for PCle/NVMe SSD with PCle signal).
This adapter is ideal for systems that only provide SSD slot but require support for Wireless modules.
Cautions
- Unplug the AC power before installation/removal.
- This adapter only provides physical pin mapping; protocol incompatibility will prevent operation.
For further technical details, consult the official M.2 specification or contact your hardware provider.
Application Examples
Expand your free storage slots for Wi-Fi modules.
New Version, More Possibilities
ACM2BM-2E1-2 is compatible with the NVIDIA Jetson Orin Nano Developer Kit.
Single Application Mode on PC Motherboard
