Class-Leading Performance

ROCK Pi has a modern and powerful hexa-core ARM-based processor, RK3399 inside, it offers significantly improved performance versus other popular SBC boards. All models are equipped with LPDDR4 3200Mb/s RAM. Furthermore, you can add high-performance eMMC modules, to boost all applications performance.

Maker Friendly, IoT Connectivity

ROCK Pi features maker friendly expansion options, including a 40-pin GPIO interface that allows for interfacing with range inputs from buttons, switches, sensors, LEDs, and much more. ROCK Pi also features a Gbit LAN for the network, with dedicated bus and controller, it works without latency under heavy load network applications. Onboard 802.11 ac wifi offers 2.4G&5G WLAN connectivity. With Bluetooth 5.0, ROCK Pi benefits-improved Bluetooth speed and greater range. ROCK Pi also features one USB 3.0 host and one USB 3.0 OTG ports, each 5Gbps/s, working independently. The USB 3.0 OTG can work as a USB device such as Android ADB or USB gadgets. A hardware switch is provided for OTG mode switch.

AI Capabilities

ROCK Pi supports mainstream AI stack with GPU acceleration. Furthermore, a dedicated hardware NPU accelerator coming up next for ROCK Pi will boosts complex Machine Learning algorithm and reduce the power. Industrial standard MIPI CSI connector makes it easy to connect existing cameras to ROCK Pi and ROCK Pi also supports industrial standard MIPI DSI for LCD and touch screen. With the hardware-accelerated algorithm, it's great for Computer Vision application, Robotics and much more.
