Tang Nano 9K is an exquisite development board based on the Gowin GW1NR-9 FPGA chip featuring 6480 flip flops and an extended DRAM of 64Mbit. Compared to the predecessor Tang Nano 1K and Tang Nano 4K with about 1152 and 4608 LUTs respectively, Tang Nano 9K has pushed the limits to around 8640 LUT4 logic units. These logic units can not only be used for various complex logic circuit designs but also used for running a complete PicoRV soft-core. It meets various needs of users, such as learning FPGA, verifying softcore, and further design.

This board contains a USB Type-C interface for the power supply and downloading code. There is a JTAG downloader on the FPGA board, so you can simply use a USB cable connected to the board to download the code without an extra downloader outside the board.

It is equipped with an HDMI connector, RGB screen interface connector, SPI screen connector, 32Mbit SPI flash, and 6 LEDs. Tang Nano 9K loses the Cortex-M3 core and support for the OV2640 camera, but gains a MicroSD card, more display interfaces, a more complete debugger, and obviously extra logical units.
