Tang Nano 4K

Edit on 2022.08.16


Tang Nano 4K is a development board designed based on Gowin little-bee GW1NSR-LV4C FPGA chip. The board is equipped with camera interface and HDMI interface. There is also an onboard USG-JTAG debugger, which make it convinent for users to use. Its Cortex-M3 hardcore can help users study mcu.

Development methods


  • GOWIN IDE verision should over v1.9.7.01 Beta.
  • The programmer application used for burning FPGA should be this one: Click me
  • Visit Install-IDE to install IDE.

Burn methods

Tang Nano 4K contains a on-board BL702 chip, used for burning GW1NSR-4C chip. Just connect this coard with computer and use this GOWIN programmer to burn bitstream, not need extra debugger to download.



  1. If you have trouble with this board, you can join our telegram (t.me/sipeed) or contact us on twitter (https://twitter.com/SipeedIO).

  2. For Fpga burning we require using this Programmer application. Because other version Programmer application may fail burning this board.

  3. If you meet problems, please visit problems first, normally most problems will be solved after using this programmer Click me.

  4. For debugging Cortex-M3, we suggest to use serial-port debug way. If you are excellent enough you can try other ways to debug it.
