Overview
The NanoPi R76S is FriendlyElec's compact dual-2.5GbE network appliance built around the Rockchip RK3576 — an octa-core SoC combining four Cortex-A72 performance cores with four Cortex-A53 efficiency cores, and a 6 TOPS NPU. At just 58×58mm it matches the footprint of the popular R3S/R4S family but upgrades networking to dual 2.5 Gigabit PCIe Ethernet ports.
The 2.5GbE ports enable multi-gigabit routing and bridging without external adapters — a key advantage for home lab users on 2.5G switches, multi-gig fiber connections, or NAS-to-router direct links. RAM is 2GB or 4GB LPDDR4X, storage is 32GB eMMC, and a microSD slot provides a fallback boot or storage option.
Video output is available via HDMI (up to 4096×2304@60Hz), and optional M.2 SDIO WiFi modules (RTL8822CE or compatible) can be added via the E-Key slot for wireless capability. A USB 3.2 Gen 1 Type-A port handles USB storage and peripherals, while a 12-pin FPC connector exposes UART, I2C, and GPIO for light GPIO expansion needs.
FriendlyWrt, Armbian, OpenWrt, Ubuntu, and Debian are all supported. The R76S is a popular choice for WireGuard/OpenVPN gateways, multi-gigabit home routers, Pi-hole DNS servers, and compact Docker hosts where network throughput matters more than raw compute.
Use Cases
6Home Lab Networking
Networking equipment for home lab environments including high-speed NICs, switches, and time servers.
IoT Gateway
Acting as a local IoT gateway that aggregates data from sensors, runs MQTT broker, Node-RED, or Home Assistant, and bridges to the cloud.
Home Server
Used as a low-power home server for file sharing, self-hosted apps, and local services — often running Docker, Home Assistant, or similar on Armbian/Debian/Ubuntu.
Network Automation
Automate network tasks, monitor connectivity, and control networked devices via WiFi and Ethernet.
Embedded Linux
Running a full Linux distribution in embedded or headless applications, such as servers, gateways, edge devices, and automation controllers.
Wired Networking
