VisionFive JH7100開發板 RISC-V架構單板計算機，香蕉派合作款 賽昉科技

　　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.
StarFive VisionFive JH7100 是世界上第一代經濟實惠的 RISC-V 板，旨在運行 Linux。 基於 RISC-V 架構，VisionFive 將開源推向新的高度，為開發人員提供更多的自由和動力來創新和設計行業領先的解決方案。 這不是 Banana Pi 社區的官方開發板，但 Banana Pi 開源社區和 StarFive 緊密合作，共同推進 risC-V 開源硬件。

　　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.
VisionFive 是第一代經濟實惠的 RISC-V 計算機，旨在運行 Linux。 它是完全開源的，具有開源軟件、開放硬件設計和 RISC-V 開放架構。它由具有 4GB/8GB LPDDR4 RAM 變體的 RISC-V SiFive U74 雙核 64 位 RV64GC ISA SoC 提供支持，具有豐富的 I/O 外圍設備，例如 USB 3.0 端口、40 針 GPIO 接頭、千兆以太網連接器、Micro-SD 卡插槽等等。VisionFive 還具有豐富的 AI 功能，包括神經網絡引擎和 NVDLA 引擎。 它具有板載音頻和視頻處理功能，並具有用於視頻硬件的 MIPI-CSI 和 MIPI-DSI 連接器。 它具有 Wi-Fi 和藍牙 (BLE) 的無線功能，並具有廣泛的軟件兼容性，包括對 Fedora 的支持。

【VisionFive JH7100 硬件規格】：

• 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.
  每個 GPIO 引腳可以安全地汲取 39 mA 的最大電流，而所有 GPIO 組合時的最大電流汲取應小於 100 mA。 請考慮到這一點，否則您最終會破壞 GPIO 引腳。
• All GPIOs can be configured to support different functions including but not limited to SDIO, Audio, SPI, I2C, UART and PWM.
  所有 GPIO 均可配置為支持不同的功能，包括但不限於 SDIO、音頻、SPI、I2C、UART 和 PWM。
