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.

  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). Leaving message below is also OK.
  2. Visit Tang questions first if you have any trouble.
  3. Debugging Cortex-M3, we suggest to use serial-port debug way. If you are excellent enough you can try other ways to debug it.
  4. THe HDMI ports are multiplexed as IO and routed to the pin headers. The actual results of the IO which are multiplexed with HDMI pins on the pin headers may not be consistent with what you want because of the external pull up.
