Features: brand new and high quality TangNano 9K is a compact development board base on Gowin GW1NR-9 FPGA chip. It is HDMI-compatible connector, RGB interface screen connector, SPI screen connector, SPI FLASH and 6LEDs allow users to easily and quickly perform FPGA verification, RISC-V soft core verification and functional prototype-verification. The 8640 LUT4 logic-unit owned by GW1NR-9 can not only be used to design various complex logic-circuits, but also can run a complete PicoRV soft core, which meets the various need of users to learn FPGA, verify-soft core and in-depth design. It supports hardware description language, and can quickly realize related work such as calling IP-core, code synthesis, placement and routing, and bit-stream file generation in the FPGA development process. Users only need to use the USBC cable to connect the development board to the computer to complete the download operation, without the need to purchase an additional downloader and cumbersome wiring.
