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
PerformanceROCK 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
ConnectivityROCK 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 CapabilitiesROCK 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
needNecessary1. ROCK Pi 4 main board* ROCK Pi 4 Model A or Model
B2. 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 HD-MI Cable* ROCK Pi 4 is
equipped with a full sized HD-MI connector. HD-MI capable monitor
is recommended.* HD-MI 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. Optional1. 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. PerformanceCPU PerformanceROCK Pi
