Radxa E25 (Compact Edge Board/Rockchip RK3568/Quad-Core Cortex-A55 2.0GHz/Up to 8GB LPDDR4/5-Port Managed Ethernet Edge Router) Review
Radxa E25 compact edge computing board built on the Rockchip RK3568, up to 8GB LPDDR4 RAM, five Gigabit Ethernet ports with hardware switch/routing support, an M.2 NVMe slot, and a small NPU, aimed at edge networking and gateway deployments.
With five wired Ethernet ports on one small board, the E25 is built for the specific job of sitting between several network segments -- a home lab with VLANs, a small office needing managed switching with a Linux brain attached, or an IoT gateway aggregating multiple wired sensor networks.
Overview
Radxa's E-series targets industrial and edge-networking deployments rather than general hobbyist use, and the E25 packs five independent Gigabit Ethernet ports plus RK3568's CPU and small NPU into a fanless board meant to run OpenWrt, VLAN-aware Linux router stacks, or lightweight edge-AI gateway software.
Performance & Connectivity
An M.2 M-key NVMe slot supports fast local storage for logging or caching, while the onboard NPU can handle basic traffic-classification or vision inference at the network edge. No wireless radio or GPIO header keeps the design focused purely on wired networking and edge compute.
Comparison to Alternatives
Against the FriendlyElec NanoPi R5S, the E25 offers three more Ethernet ports for larger network topologies, at a similar RK3568-based CPU performance level. Compared to the Hardkernel ODROID-M1, the E25 leans further into multi-port networking rather than balancing NAS and router roles.
