StarFive VisionFive JH7100 RISC-V Single Board Computer
Contents
Introduction
StarFive VisionFive JH7100 is world‘s first generation of affordable RISC-V boards designed to run Linux. Based on RISC-V architecture, VisionFive pushes open-source to the next level and gives developers more freedom and power to innovate and design industry-leading solutions. This is not an official development board for the Banana Pi community, but the Banana Pi open Source community and StarFive work closely together to advance risC-V open source hardware.
VisionFive is the first generation of affordable RISC-V computers designed to run Linux. It is fully open-source with open-source software, open hardware design and RISC-V open architecture.It is powered by RISC-V SiFive U74 Dual-Core 64-bit RV64GC ISA SoC with 4GB/8GB LPDDR4 RAM variants and has rich I/O peripherals such as USB 3.0 ports, 40-pin GPIO header, Gigabit Ethernet Connector, Micro-SD card slot and much more.VisionFive also has rich AI features with Neural Network Engine and NVDLA Engine. It has onboard audio and video processing capabilities and has MIPI-CSI and MIPI-DSI connectors for video hardware. It has wireless capabilities with Wi-Fi and Bluetooth (BLE) and has a wide software compatibility including support for Fedora.
