ROC-RK3308-CC 256M/8GB Quad-Core 64-Bit open source AIoT motherboard

It is a miniature and compact main board which is equipped with a cost-effective RK3308 Core Processor and a high-performance CODEC.

It can support various artificial intelligence and IOT operating systems, and can be configured with six microphone array board and POE expansion board.

ROC-RK3308-CC is a kind of AI+IOT open source main board incorporating many kinds of functions.


Cost-effective Quad-core Processor

It's equipped with cost-effective RK3308 64-Bit Quad-Core ARM Cortex-A35 processor, frequency up to 1.3GHz, and with high-performance CODEC and VAD, which can be used for development of the smart audio solution, automatic speech recognition, etc.


Support Operating Systems And Services

ROC-RK3308-CC supports the Buildroot system now and is about to support ROS, AliOS Things and other operating systems. The voice service function supports three-voice suits: Baidu DuerOS, AISpeech, iFLYTEK, and will support Amazon Alexa later. Rich operating system/service support for AIOT development and product application easily.


Configure Far-field Microphone Array Board

It can be configured with a far-field microphone array board, including 6 digital microphones, 12 three-color LEDs, 5 keys. It supports keyword wakeup, echo cancellation and noise reduction, VAD (Voice Activation Detection) and sound source location etc., which can significantly improve the accuracy and precision of automatic speech recognition.


Support MCU Display Screen

The main board can support MCU Display Screen with the maximum resolution of 480P, which can make display simpler and more convenient.


Rich Expansion Interfaces

Equipped with 40Pin expansion interfaces, including I2C x 3, LCD, PWM x 3, SPI x 1, I2S x 1, SPDIF RX, UART x 2 (one UART is used as Debug) and other interfaces, and can support POE expansion.

sOpen SDK

Open SDK, tutorials, technical materials and development tools to make development easier and more convenient.
