ROCK PI is a Single Board Computer (SBC) in an ultra-small form factor that offers class-leading performance while leveraging outstanding mechanical compatibility. The ROCK PI offers makers, IoT enthusiasts, hobbyists, PC DIY enthusiasts and others a reliable and extremely capable platform for building and tinkering their ideas into reality.
This is the documentation for ROCK Pi 4, written by Radxa Team with community contributions.

ROCK Pi 4 is a Rockchip RK3399 based SBC(Single Board Computer) by Radxa. It can run android or some Linux distributions.
ROCK Pi 4 features a six core ARM processor, 64bit dual channel 3200Mb/s LPDDR4, up to 4K@60 HD-MI, MIPI DSI, MIPI CSI, 3.5mm jack with mic, 802.11 ac WIFI, Bluetooth 5.0, USB Port, GbE LAN, 40-pin color expansion header, RTC. Also, ROCK Pi 4 supports USB PD and QC powering.

ROCK Pi 4 comes in two models, Model A and Model B, each model has 1GB, 2GB or 4GB ram options.


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 and optional high performance eMMC modules, boost all applications.


Maker Friendly, IoT Connectivity
ROCK Pi features maker friendly expansion options, including a 40-pin GPIO interface that allow for interfacing with a range inputs from buttons, switches, sensors, LEDs, and much more.

ROCK Pi also features a Gbit LAN for network, with dedicated bus and controller, it works without latency under heavy load network applications. On board 802.11 ac wifi offers 2.4G&5G WLAN connectivity. With Bluetooh 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 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. Further more, 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 exsit cameras to ROCK Pi and ROCK Pi also supports industrial standard MIPI DSI for LCD and touch screen. With hardware accelerated algorithm, it's great for Computer Vision application, Robotics and much more.


What you need

1. ROCK Pi 4 main board
* ROCK Pi 4 Model A or Model B

2. One of the Storage media below:
* μSD card, larger than 8GB.
* eMMC Module , larger than 8GB with eMMC to μSD converter board.

3. Power supply
* The ROCK Pi 4 is powered by Type-C port and has a wide range of input voltage, from 9V to 21V. The Pi supports USB Type-C PD 2.0 with 9V/2A, 12V/2A, 15V/2A and 20V/2A. Besides, the Pi supports QC 3.0/2.0 with 9V/2A and 12V/1.5A.
* The Type-C cable you using needs to support data communication. We call it USB Type-C charging data cable.
