This hardware user manual provides information about the features and signals available on ROCK Pi S board.
Processor
The Rockchip RK3308 Soc used in ROCK Pi S RK3308 is a high-performance Quad-core application processor designed for intelligent voice interaction, audio input/output processing, and other digital multimedia applications. Embedded rich audio interfaces, such as I2S, PCM, TDM, PDM, SPDIF, HDMI ARC and so on, can meet different audio application development, reduce hardware development complexity and development cost.
- Quad-core ARM Cortex-A35CPU
- Full implementation of the ARM architecture v8-A instruction set
- ARM Neon Advanced SIMD (single instruction, multiple data) support for accelerated media and signal processing computation
- ARMv8 Cryptography Extensions
- In-order pipeline with symmetric dual-issue of most instructions
- 256KB unified system L2 cache
- Include VFP v3 hardware to support single and double-precision operations
- Integrated 32KB L1 instruction cache, 32KB L1 data cache with 4-way set associative
- TrustZone technology support
Networking
ROCK Pi S has 100M Bit Ethernet port, equipped with 2.4GHz 802.11 b/g/n/i/e WIFI and Bluetooth 4.0.
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 S has a USB 2.0 Type-A host connector and a USB 3.0 Type-C OTG connector. It also has two 26-pin Header.
TF Card Interface
The TF card can be used as a system storage or an external storage. When it's used as a system storage, you had better choose the ones with storage space larger than 8GB. When it's used as an external storage, you can choose the ones with storage space up to 128GB. When the TF card is inserted into the TF card slot, the device will be automatically recognized by the system.
The TF card interface pin specification shows below.
| Pin# | Name |
|---|---|
| 1 | SDMMC0_D2 |
| 2 | SDMMC0_D3 |
| 3 | SDMMC0_CMD |
| 4 | VCC3V3_SYS |
| 5 | SDMMC0_CLK |
| 6 | GND |
| 7 | SDMMC0_D0 |
| 8 | SDMMC0_D1 |
| 9 | SDMMC0_DET_L |
| 10 | GND |

Buttons
The ROCK Pi S Board presents two buttons. They are Reset key and Maskrom key.
The Reset button is closer to the Type-C port than the Maskrom button.
The Reset button serves as the hardware reset button. Short press and release the button, the system will be rebooted.
The Maskrom Button is for firmware flash/upgrade. .
General purpose input-output (GPIO) connector
ROCK Pi S has two 26-pin expansion header. Each pin is distinguished by color.
For more details, see the GPIO page.
