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.

Notes:

  • Each GPIO pin can safely draw a maximum current of 39 mA, whereas the maximum current draw when all GPIOs are combined should be less than 100 mA. Please take this into account or otherwise you will end up destroying the GPIO pins.
  • All GPIOs can be configured to support different functions including but not limited to SDIO, Audio, SPI, I2C, UART and PWM.
