Radxa Dual 2.5G Router HAT All-in-One Networking & Storage Expansion for SBCs - RA027G3
The Radxa Dual 2.5G Router HAT is a high‑performance expansion board specifically engineered for Radxa SBCs and the Raspberry Pi 5.
This HAT significantly enhances network and storage capabilities through its integrated PCIe Gen3 switch chip, which expands a single PCIe interface into multiple downstream ports:
- Two 2.5GbE Ethernet ports powered by RTL8125BG controllers
- One M.2 M Key slot for NVMe SSDs
- One FPC connector with PCIe signals for additional expansion
The HAT features a 40P IPEX connector with PCIe Gen3 2‑lane capability, though the included adapter board utilizes only 1‑lane due to limitations of compatible SBCs.
With its exceptional network bandwidth, flexible storage options, and expansion capabilities, the Radxa Dual 2.5G Router HAT is ideal for building high‑performance network devices, edge computing platforms, and embedded systems.
