The MaixBit development board is an AIOT development board designed based intelligent computing chip K210 (RISC-V architecture 64-bit dual-core) of Canaan Kanzhi Technology The development board is compact and powerful, with onboard Type-C interface and USB-UART circuit. Users can directly connect to the computer for development through the USB Type-C cable. It is equipped with 128Mbit Flash, LCD, , Micro-SD card and other interfaces and leads all IOs to facilitate user expansion The MaixBit development board uses K210 as the core unit, which is very powerful. The chip has a built-in 64-bit dual-core processor and 8M on-chip . It has outstanding performance in AI machine vision and hearing performance It has built-in 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 application scenarios, and can also perform pre-processing of voice direction scanning and voice data output It not only supports conventional MCU functions, but also excels in machine vision and machine hearing, such as face recognition, object recognition, microphone array applications, etc K210 chip basic parameters: Core: RISC-V Dual Core 64bit, with FPU Main frequency: 400MHz (can be overclocked to 600MHz) : built-in 8M Image recognition: QVGA@60fps/VGA@30fps Speech recognition: microphone array (8mics) Network model: support YOLOv3/Mobilenetv2/TinyYOLOv2/face recognition, etc. Deep learning framework: support mainstream frameworks such as TensorFlow/Keras/Darknet/Caffe Peripherals: FPIOA, UART, GPIO, SPI, IPC, I2S, Video processing: Neural network processor (KPU) FPU meets IEEE754-2008 standard Audio processor (APU) Fast Fourier transform accelerator() Development board parameters: Onboard resources: buttonsx2, RGB lightsx1, MEMS Microphonex1, USB to UART, 128Mbit Flashx1 Onboard interface: USB Type-C interface, 24PIN camera interface, 24PIN LCD interface, Micro-SD card slot, all 10 pins are lead out Power supply voltage: 5.0V@300mA (power supply current must be 300mA) Operating temperature: -30-85 Software development: Chip : FreeRTOS, RT-Thread, etc. Development environment: for MaixPy IDE, PlatformIO IDE for IDE, etc. Programming language: C, C++, MicroPython Due to different batches, the printed words on the product will be different, which does not affect use Colour:Black Material:PCB Package Contents: 1x Development Board Only 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. The measurement allowed error is +/- 1-3cm.
