Overview
The Radxa ROCK 5B+ is an upgraded version of the popular Rock 5B, built around the Rockchip RK3588 and fitting into a compact 100×72mm Pico-ITX footprint. 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.
