Intelligent  IoT Development Kit

The micro IoT main board with a high-resolution display is combined into a high-performance intelligent IoT development kit that supports various IoT systems, audio systems and services, and Buildroot+Qt application development. With rich expansion interface, it can be quickly applied to intelligent IoT, intelligent Automatic Speech Recognition (ASR), Human Machine Interaction(HMI), industrial control, intelligent robot, etc.

Quad-core 64-bit IoT Processer

A special IoT processer for RockChip RK3308B, based on ARM quad-core 64-bit Cortex-A35 kernel, 1.3GHz frequency, and integrated high-performance Codec and Hardware VAD, directly supports at most 8-channel analog MIC array.

Powerful Display Capability

It with powerful display drive capability and can support up to 1024*720 resolution, suitable for HMI, smart home, AIOT and other screen display applications.

Support IoT Systems And Services

t can support a variety of voice systems and services, such as Buildroot（Linux/QT）embedded system, ROS(Robot os), and iFLYTEK, Amazon Alexa. Rich operating systems/services support can use for IoT, intelligent speech recognition and other products easily.

Buildroot+QT Application Development

It can support Buildroot + QT application development. The open source QT application program provided by the SDK includes music application (supporting various audio formats, such as mp3, wav, ogg, etc.), video application (supporting various video formats, such as mp4, avi, flv, etc.), picture application, and setting application (various control functions: WiFi connection, volume, brightness adjustment, language switch).

Voice Intercom 

Not limited by transmission distance, keep the call in the place with network, realize functions such as sensitive word filtering and the automatic storage of call recording. It widely used in fields such as finance, education, transportation, medical treatment, etc.

Rich Expansion Interfaces

With multiple expansion interfaces such as PWM×8, I2C×3, UART×5, SPI×2, I2S×2, ADC×4, LineOut, and so on, to meet the requirements of various application scenarios.

Open SDK

Equipped source code, tutorial, technical materials, and development tools are provided, making development easier and more convenient.

Application

Widely used in scenes such as IoT, intelligent voice interaction, audio input or output, etc.
