Green PCB adapter board with M.2 E-Key slot, 16-pin ribbon cable and gold SMA antenna connector

SMUGDESK

SMUGDESK PCIe to M.2 E-Key Adapter for Raspberry Pi 5, 16P Cable & SMA Antenna

SKU CH-J51M-16B0S

Adds an M.2 E-Key slot with 16-pin cable and SMA antenna for Raspberry Pi 5 wireless expansion

  • Adds Wi-Fi and Bluetooth via M.2 E-Key slot on Raspberry Pi 5
  • 16-pin cable connects adapter directly to Raspberry Pi 5 PCIe interface
  • SMA antenna port allows external antenna for stronger wireless signal
  • Supports standard NGFF M.2 E-Key wireless cards for flexible upgrades
  • Mounting holes enable secure installation inside Raspberry Pi case

Raspberry Pi 5 wireless expansion

This PCIe to M.2 E-Key adapter board is tailor-made for Raspberry Pi 5, providing a reliable expansion solution for wireless network modules. It utilizes the PCIe interface of Raspberry Pi 5 to expand a standard M.2 E-Key slot, allowing users to install various NGFF M.2 E-Key wireless cards to upgrade WiFi and Bluetooth performance. Comes with a matched 16P connection cable for quick connection between the adapter and Raspberry Pi 5.

Sustained signal integrity

The PCB adopts optimized circuit design to guarantee stable PCIe signal transmission and reduce signal interference during continuous operation. Standard M.2 E-Key slot fits mainstream NGFF wireless adapters for consistent connectivity. Pre-reserved mounting holes facilitate fixed installation inside equipment housing to maintain reliable contact over extended periods.

Thermals noise power in normal use

The onboard SMA antenna connector supports connecting external high-gain antennas, effectively improving wireless signal reception and transmission range without increasing internal heat. Compact layout and passive design ensure silent operation and minimal power draw from the Raspberry Pi 5 itself. Perfect for smart home gateway construction, media server, industrial IoT projects and wireless communication development based on Raspberry Pi 5.

Questions about this item

Does the 16P cable add noticeable heat or power draw when the adapter runs continuously?

The 16P cable simply carries the PCIe link to the M.2 E-Key slot; power consumption and heat depend on the wireless card you install, not the adapter itself.

What else must I already own for this adapter to work?

You need a Raspberry Pi 5 and a standard NGFF M.2 E-Key wireless card; the board, 16P cable and SMA antenna connector are included.

Will this adapter fit inside my existing Raspberry Pi case alongside the original board?

The compact PCB has pre-reserved mounting holes designed for installation inside a Raspberry Pi 5 case, but internal clearance varies by case model.
