Intruduction

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 HDMI, 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 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

Necessary

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.

4. USB Keyboard and Mouse

• With four USB-A connectors, ROCK Pi 4 can be equipped with a full sized keyboard and mouse.

5. Monitor and HDMI Cable

• ROCK Pi 4 is equipped with a full sized HDMI connector. HDMI capable monitor is recommended.
• HDMI EDID display data is used to determine the best display resolution. On monitors and TVs that support 1080p (or 4K) this resolution will be selected. If 1080p is not supported the next available resolution reported by EDID will be used. This selected mode will work with MOST but not all monitors/TVs.

6. USB to TTL serial cable

• ROCK Pi 4 exports a dedicated serial console, which can access the low level debug message.

7. USB Male A to Male A cable

• If you want write image on ROCK Pi 4 from USB OTG port or use fastboot/adb commands you need an USB Male A to Male A cable to connect ROCK Pi 4 and PC.

Optional

1. μSD Card Reader

• For flashing the image into μSD Card or eMMC Module.

2. USB type A to type A cable

• This is needed for fastboot/adb commands.

3. USB to TTL serial cable

• This is needed for serial console.

4. Ethernet cable

• ROCK Pi 4 supports Internet access via WIFI or Ethernet.
• An Ethernet cable is used to connect your ROCK Pi 4 to a local network and the Internet.

5. Camera Module

• ROCK Pi 4 supports camera function.

6.LCD Module

• ROCK Pi 4 supports LCD display function.

7. Audio cable

• Audio can be played through speaker or headphones using a standard 3.5mm jack.
