$18 Tang Nano 4K FPGA board comes with HDMI output, optional camera

Sipeed’s Tang Nano 4K FPGA board is an upgrade to the company’s Tang Nano FPGA board with a more powerful GOWIN GW1NSR-LV4C FPGA with 4608 LUT (instead of 1152) and a Cortex-M3 microcontroller embedded into the chip.

Like the previous board, the new Tang Nano 4K features a USB-C port for power and downloading the bitstream, but replace the RGB LCD interface with an HDMI port, and adds support for an optional OV2640 camera.

The board can be programmed using Verilog with the GOWIN IDE available for Windows and Linux. One sample is provided to stream the camera input to an HDMI display. You’ll find documentation and download links on Sipeed Wiki (in Chinese only for now), and the code on Github.

Sipeed Tango Nano 4K FPGA board has just launched on Aliexpress for $18 without a camera or $21 with an OV2460 camera.
