WIRELESS MOBILE MINI TRAVEL ROUTER - Convert a public network(wired/wireless) to a private Wi-Fi for secure surfing. Create a secure Wi-Fi hotspot quickly

The FriendlyElec NanoPi R4S is a compact powerhouse built for developers and tech enthusiasts who need serious networking performance in a tiny package. Powered by the RK3399 SoC and 4GB LPDDR4 RAM, this mini router delivers dual gigabit Ethernet ports that actually hit the advertised speeds—941 Mbps up and down. Whether you’re building a custom firewall, setting up a home NAS, or creating IoT projects, this board gives you the flexibility of OpenWRT with the reliability of enterprise-grade hardware.

What sets the R4S apart is its open-source foundation. Running FriendlyWrt (an OpenWRT distribution), you get full control over your network without vendor lock-in or bloatware. Docker CE support means you can containerize applications and run multiple services simultaneously. The dual Ethernet setup—one native from the SoC, one via PCIe conversion—makes it perfect for router applications, VPN gateways, or network monitoring setups. The included MAC chip ensures proper network identification right out of the box.

Who Is This For?

This isn’t a plug-and-play consumer router. The R4S targets developers, network admins, and hobbyists comfortable with Linux and command-line interfaces. You’ll need to supply your own microSD card for the OS, a 5V/3A power supply, and a WiFi module if wireless connectivity is required. If you’re looking to learn OpenWRT, build a custom travel router for secure public WiFi access, or deploy a lightweight home server, this board offers exceptional value. It’s ideal for anyone who wants networking hardware they can truly customize and control.

Bottom Line

The NanoPi R4S delivers genuine gigabit performance, open-source flexibility, and solid build quality at a competitive price point. You’re getting real networking capability without the limitations of consumer routers. Just remember this is a DIY solution—budget time for setup and configuration. For developers and enthusiasts ready to build their own network solutions, the R4S is one of the best mini router platforms available.
