It addresses the most-requested improvements: LPDDR5 memory (up to 32GB), onboard eMMC flash options, integrated WiFi 6 and Bluetooth 5.2 (no separate module needed), and two M.2 Key-M PCIe 3.0 x2 sockets for dual NVMe SSD configurations. Networking is upgraded to 2.5 Gigabit Ethernet with PoE support, and a new M.2 Key-B socket plus dedicated SIM card slot enables 4G LTE or 5G cellular connectivity without sacrificing an NVMe slot. Video output reaches four independent simultaneous displays: two HDMI 2.1 (up to 8K@60Hz), one DisplayPort via USB-C (up to 8K@30Hz), and one MIPI DSI. A micro HDMI input (4K@60Hz) enables video capture. The RK3588's 6 TOPS NPU makes it a capable platform for on-device AI inference, computer vision pipelines, and edge ML workloads. A standard 40-pin GPIO header provides I2C, SPI, UART, and general GPIO access for expansion. Armbian, Ubuntu, Debian, and Android are all supported with well-maintained images. The ROCK 5B+ is popular for NAS builds (dual NVMe + 2.5GbE), home lab servers, Kubernetes edge nodes, and digital signage deployments where sustained compute throughput and multi-display support matter. ## Where to Buy - [Radxa (AliExpress)](https://openhardware.directory/r?to=https%3A%2F%2Fradxa.com%2Fproducts%2Frock5%2F5bp%2F&ref=openhardware.directory&product=radxa-rock-5b-plus&source=md-export) — 70.00 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fradxa.com%2Fproducts%2Frock5%2F5bp%2F&ref=openhardware.directory&product=radxa-rock-5b-plus&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fwiki.radxa.com%2FRock5%2F5b&ref=openhardware.directory&product=radxa-rock-5b-plus&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fwww.rock-chips.com%2Fa%2Fen%2Fproducts%2FRK35_Series%2F2022%2F0926%2F1660.html&ref=openhardware.directory&product=radxa-rock-5b-plus&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2Fradxa&ref=openhardware.directory&product=radxa-rock-5b-plus&source=md-export) ## Tags `rk3588`, `linux`, `arm`, `sbc`, `nas`, `wifi6`, `npu`, `radxa`, `pico-itx`, `lpddr5`, `nvme` ## Images ![Radxa ROCK 5B+](https://nbg1.your-objectstorage.com/openhardware-directory/entities/radxa-rock-5b-plus/17ab2164147d.webp) ![Radxa ROCK 5B+](https://nbg1.your-objectstorage.com/openhardware-directory/entities/radxa-rock-5b-plus/ca1027092500.webp) --- [View full device page](https://openhardware.directory/devices/radxa-rock-5b-plus)
