Product information "ROC-RK3308-CC Quad-Core 64-Bit AIOT Main Board"


Quad-Core 64-Bit AIOT MainBoard

It is a miniature and compact main board which is equipped with a cost-effective RK3308 Core Processorand 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 to1.3GHz, and with high-performance CODEC and VAD, which can be used for development of the smart audiosolution, automatic speech recognition, etc.


Support Operating Systems And Services

ROC-RK3308-CCsupports the Buildroot system now and is about to support ROS, AliOS Things and other operatingsystems. The voice service function supports four-voice suits: Baidu DuerOS, AISpeech, iFLYTEK, and Amazon Alexa later. Rich operating system/service support for AIOT development and productapplication easily.


Configure Far-fieldMicrophone Array Board

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


Support MCU Display Screen

Themain board can support MCU Display Screen with the maximum resolution of 480P, which can make displaysimpler andmore convenient.


Rich Expansion Interfaces

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


Open SDK

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