5 Electrical Specification

5.1 Power Requirements

The ROCK 5B supports various power supply technologies including smart power adapter as well as
fixed voltage:• USB Type‑C™ PD Version 2.0 with 9V/2A, 12V/2A, 15V/2A and 20V/2A.

• Power adapter with fixed voltage in 5V to 20V range on the USB Type‑C port

• 5V Power applied to the GPIO PIN 2 & 4

The recommended power source should be able to produce, at least, 24W without a M.2 SSD or 30W
with a M.2 SSD.

6 Operating Conditions
The ROCK 5B has been designed to operate between 0°C to 50°C.
This temperature range was defined based on typical usage where the efficient use of Arm big.LITTLE
technology can automatically select which processor core to utilise for a given task, the result of whichis minimal heat generation and responsive user experience.
The ROCK 5B is built on a high‑performance mobile chipset which is designed to oper‑ ate for extended
durations on batteries with efficiency at its core. As with all electronic devices heat is a by‑productof operation which increases with performance and workload; during basic use cases such as web
browsing, editing text or listening to music the SoC will automatically select the smallest processors
available or dedicated hardware accelerators to reduce heat generation thus reserving the higher per‑formance processors and thermal window for demanding tasks as and when required.
The SoC (RK3588) is specified to limit its maximum internal temperature to 80°C before throttling theclock speeds to maintain reliability within the allowed temperature range. If the ROCK 5B is intended
to be used continuously in high performance applications, it may be necessary to use external coolingmethods (for example, heat sink, fan, etc.) which will allow the SoC to continue running at maximum
clock speed indefinitely below its prede‑ fined 80°C peak temperature limiter.

7 Peripherals
7.1 GPIO Interface
The ROCK 5B offers a 40 pin GPIO expansion header which provides extensive compatibility with awide range of accessories developed for the SBC market.

7.2 Network
ROCK 5B offers a 10/100/1000/2500 Mbit RJ45 connector for wired networking. With additional
PoE module/HAT, ROCK 5B can be powered by ethernet cable via RJ45 port by a PoE capableswitch/router.

7.3 eMMC Socket
ROCK 5B offers a high speed eMMC socket for eMMC modules which can be used for OS and data
storage. The eMMC socket is compatible with readily available industrial pinout and form factor hard‑ware.
It is worth noting that the eMMC module shall be larger than 8GB and there is not maximum size limi‑
tation.

7.4 Camera and Display Interfaces
The ROCK 5B has one four‑lane(can be split into 2x two‑lane) MIPI CSI Camera and one four‑lane MIPIDSI Display connector. These connectors are designed for Radxa Camera and Display accessories andalso backwards compatible with standard industrial camera and display peripherals with adapter FPC
cables by Radxa.

7.5 USB
The ROCK 5B features one USB 3.0 Type‑C™ port supporting PD Version 2.0 and a DP supporting up to
4Kp60 as an alternative function.
The ROCK 5B has two USB2 HOST, one USB3 HOST and one USB3 OTG/HOST type‑A connectors. The
power output across these ports is 2.8A in aggregate over the four connectors.

7.6 HDMI Output
The ROCK 5B has two HDMI output ports(Type A), both support CEC and HDMI 2.1 with resolutions of
8Kp60 and 4Kp60 respectively.

7.7 HDMI Input
The ROCK 5B has one HDMI input port(Type D), which support HDMI 2.1 input with resolutions of
4Kp60.

7.8 Audio JackThe ROCK 5B supports supports high quality analogue audio output via a 4‑ring 3.5mm headphone
jack. The analog audio output can drive 32 Ohm headphones directly. The audio jack also supports
microphone input as default.

7.9 M.2 Connector
The ROCK 5B offers two M.2 connectors:• At the front a M.2 E Key with 2230 mouting hole providing PCIe 2.1 one‑lane, USB, SATA, SDIO,PCM and UART singal, supporting industrial standard M.2 WiFi 6 modules.
• At the Back a M.2 M Key socket with four‑lane PCIe 3.0 interface. A standard M.2 2280 mouting
hole is on the board to enable the deployment of a M.2 2280 NVMe SSD. Please note that M.2
SATA SSDs are not supported.

7.10 Fan Connector
The ROCK 5B has a 2pin 1.25mm header that enables users to connect a 5V fan (or other peripheral).
The fan can be PWM controlled without speed feedback.
