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. It’s the third Rockchip RK3528A board from FriendlyELEC, but the other NanoPi NEO3 Plus serves other purposes with a single Gigabit Ethernet port, a USB 2.0 port, and a GPIO header, and the previous-generation NanoPi Zero2 offers similar features. Other Rockchip RK3528A-based routers with multiple Gigabit Ethernet interfaces include the Radxa ROCK E20C (dual GbE + USB-C debug), the Radxa E24C (quad GbE + USB-C debug), and the Banana Pi BPI-M1S, which is more of a complete SBC with HDMI video output, GbE + 2.5GbE networking, wireless, and so on.
