LCPI Allwinner D1 development board 64bit RISC-V Linux SBC supports Tina Debian system

About LCPI D1 development board

LC LCPI development board is equipped with Allwinner D1 processor.Allwinner D1 is an external processor based on the R18C-V architecture and the world's first general-purpose SOC developed based on Xuantie C906.D1 integrates a 64-bit Xuantie C906 RISC-V CPU, which provides efficient computing power and runs the Linux system, making it stable and efficient, and convenient for secondary development.D1 supports H.265, H.264, MPE-1/2/4, JPEG, VC1 and other full format decoding. A standalone encoder can encode with JPEG or MJPEG.The integrated multi-ADC/DAC and I2S/PCM/DMIC/OWA audio interface can work seamlessly with the CPU to accelerate multimedia algorithms and improve user experience.The development board integrates HDMI, BT2.1+WiFi, 1xUSB OTG+1xUSB Host 1xFEL+1xRST+1xLRADC buttons, 256MB NAND Flash, 4522 model microphone, 3.5mm stereo audio output interface, 40P RGB LCD liquid crystal interface, UART serial port and other rich peripherals and 2*20Pin GPIO outlet.It is not only a microcomputer that can realize audio and video entertainment, but also can be used for Linux programming learning and project development, supporting Debian, Tina and other operating systems.
