We just wrote about the NanoPi R3S LTS dual gigabit Ethernet SBC and router with HDMI output and a speaker connector last week, but FriendlyELEC is back again with the similar NanoPi R76S equipped with two 2.5GbE ports, HDMI video output, an M.2 socket for a WiFi/Bluetooth SDIO module, and a more powerful Rockchip RK3576 octa-core SoC coupled with up to 16GB LPDDR5.
Like its predecessors, the NanoPi R76S is offered as a bare board or with a metal enclosure. It comes with a 32GB eMMC flash, microSD card slot, a USB 3.0 port for storage or wireless expansion, a USB-C port for power, a small 8-pin GPIO FPC connector, and a few buttons and LEDs.
NanoPi R76S specifications:
- SoC – Rockchip RK3576
- CPU – Octa-core CPU with 4x Cortex-A72 cores at 2.2 GHz, 4x Cortex-A53 cores at 2.0 GHz

- Optional WiFi/Bluetooth SDIO module via M.2 E-Key socket
- USB
- 1x USB 3.2 Gen 1 Type-A port
- 1x USB-C port for power and data (to flash firmware)
- Expansion – 8-pin GPIO FPC connector
- Debugging – 3-pin UART header (1.5 Mbps baudrate)
- Misc
- Power, User, and Mask buttons
- 2-pin connector for RTC battery for the HYM8563TS RTC
- 3x LEDs: SYS, LED1, and LED2
- Power Supply – 5V/3A via USB Type-C port
- Dimensions – PCB: 58 x 58 mm (8-layer PCB); enclosure: 62.5 x 62.5 x 29.2 mm
- Weight – 37.5 grams without the case, 145.5 grams with the metal enclosure
- Temperature Range – 0 to 70°C
FriendlyELEC provides a long list of supported OS and software tools: Alpine Linux, Android 14 Tablet/TV, Buildroot, Debian 12 Core, Debian 11 Desktop, FriendlyWrt 21.02/23.05/24.10 (OpenWrt fork), OpenMediaVault, Proxmox VE, Ubuntu 20.04/24.04 Desktop, and Ubuntu 24.04 Core, all with Linux 6.1 LTS and u-boot 2017.09 support. That’s pretty much the same list as for the NanoPi R3S LTS, albeit with a few variations. More technical details and links to images can be found on the wiki.
People who want to use the R76S as a headless networking device with its enclosure will again deplore the lack of access to the UART header without having to open the device, while the similar Rockchip RK3582-based Radxa E52C provides USB-C debug port for easy access to the serial console. However, note that the Radxa device does not offer HDMI output or an M.2 socket for WiFi/Bluetooth.

Most other NanoPi boards do not support WiFi and Bluetooth, but the new Rockchip RK3576 board does through an M.2 socket for an SDIO wireless module and two internal antennas.
The NanoPi R76S starts at $49 with the board only, 2GB RAM, and 32GB eMMC flash, and goes up to $99 for the module with 16GB RAM and a metal enclosure. For some reason, the company has yet to offer the AC200 SDIO wireless (WiFi 5 + Bluetooth 5.0) module as an option on the R76S page, but I could find it for $9.99 on another page.
