K210 kit adopts RISC-V processing architecture, a mini full-featured development board kit designed for machine vision and auditory multi- recognition. It can be widely used in smart homes, smart robots, security monitoring and other fieldsBoard comes with HD camera, capacitive touch screen, on-board indexing electronic components, such as three-way switches, RGB , gyroscopes, speakers, ESF8285-WIFI module, microphone interface, etc. In addition, all IO ports of the K210 chip are led out through the pin header, which is convenient for users to expand.Supports 3 development environments of Windows/Linux/ OS. When the computer and the K210 development board are connected to the same WiFi, they can communicate with each other, is, combined with IOT to achieve remote controlThe development board comes with a factory test program, but the demo program needs to be burned in by yourself.Core:RISC-V Dual Core 64bit, with FPUMain frequency :400MHz (overclocked to 600MHz)Chip manufacturing process : TSMC's ultra-low- 28-nanometer advanced manufacturing processCore instruction set : Simple instruction set RISC-VSecurity : Support firmware encryption, support AEX and SHA256 encryption algorithmsSRAM : -in 8M recognition : QVGA@6fps/VGA@30fpsSpeech recognition : microphone (8mics)AI vision: Comes with KPU, supports convolutional neural network calculations, etc.Network : Supports YOLOv3/Mobilenetv2/TinyYOLOv2/face recognition, etc. learning framework : Supports mainstream frameworks such as TensorFlow/Keras/Darknet/caffePeripherals : GPIO, FPIOA, UART, TIMER, SPI, I2C, I2SVideo processing: Neural Network Processor (KPU), FPU meets IEEE754-2008 standard, Audio processor (APU), Fast Fourier Transform Accelerator()Working temperature: -30Celsius-85CelsiusWorking voltage : 3.3V/1.8V voltage support, without level conversionColour:blackMaterial:pvcSize:100 x 70mmPackage Contents:1 x Motherboard1 x LCD touch screen1 x HD camera1 x Speaker1 x Digital Microphone1 x usb cableOnly the above package content, other products are not included.Note: Light and different displays may the color of the item in the a little different from the real thing.
