    ROCK Pi S >  Hardware >  Main Board

Processor

The Rockchip RK3308 Soc used in ROCK Pi S RK3308is a high-performance Quad-coreapplication 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 developmentcomplexity 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 L1data 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.

Peripherals

The ROCK Pi S have A USB2.0 Type-A host connector and a USB3.0 Type-C OTG connector. It also have tow 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.
