Overview
The NanoPi R2S is the quintessential budget open-source router. Powered by the Rockchip RK3328 quad-core Cortex-A53 at 1.3GHz with 1GB DDR4, it provides dual Gigabit Ethernet (one native, one via USB 3.0) in a tiny 55.6×52mm package — all for just $27.
Despite its small size and low price, the R2S handles typical home router duties with ease: NAT routing, VPN, firewall, ad blocking (Pi-hole/AdGuard), DNS, and DHCP. Running FriendlyWrt (OpenWrt), it supports hundreds of packages for network monitoring, traffic shaping, and IoT gateway functions.
With USB 2.0, microSD boot, and a metal case option, the R2S has become one of the most popular DIY router platforms worldwide. Its low power consumption (5V/2A) makes it suitable for always-on deployment as a network appliance.
