The Tang nano 9K FPGA Development Board is based on the Gowin GW1NR-9 FPGA chip. It equips with an HDMI connector, RGB screen interface connector, SPI screen connector, 32Mbit SPI flash, and 6 LEDs, so users can use it for FPGA verification, RISC-V soft core verification, and basic function verification easily and quickly.

Its 8640 LUT4 logic units can not only be used for various complex logic circuit designing but also used for running a complete PicoRV softcore. It also meets various needs of users, such as learning FPGA, verifying softcore, and further design.
