NanoPi R28S – A tiny dual GbE Rockchip RK3528A wireless SBC and router with a USB-C console port

NanoPi R28S Dual GbE router USB C Debug port

NanoPi R28S is yet another tiny dual Gigabit Ethernet single board computer or router (with a metal enclosure), and the second from FriendlyELEC to implement a USB-C console port, often requested by our readers, after the NanoPi R2S Plus launched in 2024. At just 49.5 x 49.5 x 24 mm in its metal case, the Rockchip RK3528A-powered router also features 1GB LPDDR4, a microSD card slot and an eMMC module socket for storage, WiFi 6 and Bluetooth 5.3 wireless connectivity. The USB-C ports are only used for power, eMMC firmware upgrades, and debugging, and the system doesn’t feature any USB port for data connectivity, nor any GPIO header for expansion. In other words, it’s mostly useful for networking (firewalls, soft routers), as well as IoT gateway applications. NanoPi R28S specifications: SoC – Rockchip RK3528A CPU – Quad-core ARM Cortex-A53 @ 1.8 GHz GPU – Arm Mali-450 GPU with support for […]
