The MaixBit development board is an AIOT development board designed based intelligent computing chip K210 (RISCV architecture 64bit dualcore) of Canaan Kanzhi TechnologyThe development board is compact and powerful, with onboard TypeC interface and USBUART circuit. Users can directly connect to the computer for development through the USB TypeC cable. It is equipped with 128Mbit Flash, LCD, , MicroSD card and other interfaces and leads all IOs to facilitate user expansionThe MaixBit development board uses K210 as the core unit, which is very powerful. The chip has a builtin 64bit dualcore processor and 8M onchip . It has outstanding performance in AI machine vision and hearing performanceIt has builtin multiple hardware acceleration units (KPU, FPU, , etc.), with a total computing power of up to 1TOPS, which can easily implement machine vision/auditory algorithms for various application scenarios, and can also perform preprocessing of voice direction scanning and voice data outputIt not only supports conventional MCU functions, but also excels in machine vision and machine hearing, such as face recognition, object recognition, microphone array applications, etcK210 chip basic parameters:Core: RISCV Dual Core 64bit, with FPUMain frequency: 400MHz (can be overclocked to 600MHz): builtin 8M Image recognition: QVGA@60fps/VGA@30fpsSpeech recognition: microphone array (8mics)Network model: support YOLOv3/Mobilenetv2/TinyYOLOv2/face recognition, etc.Deep learning framework: support mainstream frameworks such as TensorFlow/Keras/Darknet/CaffePeripherals: FPIOA, UART, GPIO, SPI, IPC, I2S, Video processing: Neural network processor (KPU)FPU meets IEEE7542008 standardAudio processor (APU)Fast Fourier transform accelerator()Development board parameters:Onboard resources: buttonsx2, RGB lightsx1, MEMS Microphonex1, USB to UART, 128Mbit Flashx1Onboard interface: USB TypeC interface, 24PIN camera interface, 24PIN LCD interface, MicroSD card slot, all 10 pins are lead outPower supply voltage: 5.0V@300mA (power supply current must be 300mA)Operating temperature: 3085Software development:Chip : FreeRTOS, RTThread, etc.Development environment: for MaixPy IDE, PlatformIO IDE for IDE, etc.Programming language: C, C++, MicroPythonDue to different batches, the printed words on the product will be different, which does not affect useColour:BlackMaterial:PCBPackage Contents:1x Development BoardOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
