LORDWORLD M-Key to E-Key NVME Riser Card ASM1182e 2230

SKU CH-54FN-8NAP0

Converts an M-Key NVME slot into one E-Key WLAN and one 2230 NVME port using an ASM1182e PCIe 2.0 packet switch

  • Adds WLAN and NVME to one M-Key slot via ASM1182e packet switch
  • Keeps full SSD speed with PCIe 2.0 x1 Gen2 upstream and dual downstream ports
  • Fits 2230 Key-M NVME drives only, no extra power needed
  • Works in NAS so OS boots from SSD while WLAN handles networking
  • Not compatible with B-Key SATA devices, M-Key NVME PCIe only

M-Key to E-Key NVMe Riser Card

This adapter converts an M-Key NVMe PCIe slot into an E-Key WLAN interface and a Key-M NVMe 2230 connector. It targets builders adding storage and wireless networking to compatible NAS or industrial control motherboards. The board uses an ASM1182e PCIe packet switch to split one upstream lane into two downstream lanes.

ASM1182e PCIe 2.0 Packet Switch

The integrated ASM1182e chip provides one PCIe x1 Gen2 upstream port and two PCIe x1 Gen2 downstream ports compliant with PCIe Base SPEC 2.0. No external power is required and the compact form factor suits space-constrained embedded systems. Both the WLAN card and the SSD operate simultaneously from the single M-Key source.

Gen2 x1 Bandwidth Limit

Each downstream port is limited to PCIe Gen2 x1 throughput, so the SSD and WLAN share the upstream lane's total bandwidth. The adapter only accepts M-Key NVMe PCIe interfaces and rejects B-Key SATA modules. Only 2230 Key-M SSDs are supported, so longer drives cannot be fitted.

Highlights

  • Adds WLAN and NVME to one M-Key slot via ASM1182e packet switch
  • Keeps full SSD speed with PCIe 2.0 x1 Gen2 upstream and dual downstream ports
  • Fits 2230 Key-M NVME drives only, no extra power needed
  • Works in NAS so OS boots from SSD while WLAN handles networking
  • Not compatible with B-Key SATA devices, M-Key NVME PCIe only

Questions about this item

What PCIe generation does the ASM1182e chipset support on this riser card?

The ASM1182e chipset provides PCIe 2.0 x1 upstream and splits it into two PCIe 2.0 x1 downstream ports for the E-Key WLAN and M-Key NVMe slots.

What physical slot and SSD size does this adapter require and support?

It plugs into an M-Key NVMe PCIe slot on the motherboard and accepts a single 2230 Key-M NVMe SSD plus an E-Key WLAN card simultaneously.

How is the card installed and what common mistake should be avoided?

Insert the riser into the host M-Key NVMe slot, then fit the 2230 NVMe SSD and E-Key WLAN card into the onboard connectors; do not use a B-Key SATA drive as it is electrically incompatible.
