LORDWORLD PCIe to M.2 E Key HAT for Raspberry Pi 5 16PIN

Target Platform and Purpose

This HAT adds an M.2 E-key slot to the Raspberry Pi 5 using its 16PIN PCIe interface. It accepts A/E-key and E-key wireless NIC modules and routes Bluetooth signals to the Pi through a USB connection. An onboard SMA female connector allows external antenna attachment for improved wireless range. The board is aimed at makers and developers who need to add Wi-Fi or Bluetooth capability to a Pi 5 project.

Build Integration Requirements

The HAT connects to the Pi 5 via the supplied 16PIN cable and occupies the PCIe lane on the single-board computer. An M.2 E-key wireless module must be sourced separately and installed on the HAT before the assembly is mounted. The USB link for Bluetooth consumes one USB port on the Pi 5. The SMA antenna connector requires a compatible antenna and cable, which are not included with the HAT.

Sustained Operation Behaviour

During continuous data transfer the wireless module draws power through the Pi 5 PCIe supply and the USB link, so the Pi’s own power budget must accommodate both. The SMA antenna connection maintains a stable RF path under prolonged use, reducing drop-outs compared with onboard chip antennas. Thermal performance depends on the chosen wireless module and the airflow inside the enclosure, as the HAT itself has no active cooling.
