ROCK Pi 4 > Hardware > ROCK Pi 4 Main Board
This hardware user manual provides information about the features and signals available on ROCK Pi 4 board.
Processor
The Rockchip RK3399 Soc used in ROCK Pi 4 includes 64bits hexa core processor with dual 1.8GHz Cortex-72 and qual 1.4GHz Cortex-A53, Mali T860MP4 graphics processing unit (GPU) and Internal SRAM. It has a level 1 (L1) cache and a level 2 (L2). For level 1 cache, 48KB Icache and 32KB Dcache is for each A72. 32KB Icache and 32KB Dcache is for each A53. For level 2 cache, 1024KB cache is for big cluster and 512KB cache is for little cluster.
Power supply
Via PoE
ROCK Pi 4 can be power on with ROCK Pi 23W PoE HAT.
Via Type-C port
The ROCK Pi 4A / 4A Plus/ 4B / 4B Plus / 4C is powered by USB Type C port and supports a wide range of input voltage, from 9V to 20V. The power adapter can be USB Type-C PD 2.0 with 9V/2A, 12V/2A, 15V/2A and 20V/2A protocol compatible, or Quick Charge 2.0 9V/2A, 12V/2A compatible. A dummy 9V or 12V power adapter with USB C tail will also work. Warning: 9V/12V USB C dummy power adapter is dangerous to other 5V only devices, don't mix them.
If the power adapter is PD/QC compatible, the USB power cable must support USB data communication(USB 2.0 or 3.0) between the board and the power adapter, or the power adapter will not output desired voltage wanted by the board.
Note: We don't suggest using a 5V only USB C power adapter. The board may boot but it will cause stability issue once the system load rises.
Via Type-C port
ROCK Pi 4C Plus is powered by USB Type C port with DC 5V only adapter.
Networking
On the ROCK Pi 4 Model A, B board, the Giga Bit Ethernet port is provided. From the test result, we know that the bandwidth is at least 939Mbits/sec. If you are interested in POE (Power Over Ethernet), you should try it on the Pi 4 board.
The ROCK Pi 4 Model B is equipped with 2.4GHz 802.11 b/g/n and 5G ac/a WIFI. The Pi 4B also features BT 5.0.
Two LEDs are built into the RJ-45 LAN connector. This table describes the LED states when the board is powered up and the LAN subsystem is operating.
| LED | LED Color | Led State | Condition |
|---|---|---|---|
| Link | Green | Off On |
LAN link is not established. LAN link is established. |
| Data Rate | Yellow | Blinking Off |
There is activity on this port. No link is established. |
Peripherals
The ROCK Pi 4 Model A and B have four USB-A connectors. One is for USB 3.0 OTG. One is for 3.0 HOST. And the others are for USB 2.0 HOST. The hardware switch for host/device switch may be useful when you use the USB 3.0 OTG connector. The ROCK Pi 4 may be operated with any generic USB computer keyboard and mouse. It may also be used with USB storage, USB to MIDI converters, and virtually any other device/component with USB capabilities.
The ROCK Pi 4 Model A and B are equipped with a standard 3.5mm jack. An audio lead is necessary to produce sound when there is not an HDMI cable. Audio can be played through speakers or headphones using jack. This requires you to use the Desktop volume control for configuration.
