Sipeed Tang Nano 1K FPGA Development Board (GW1NZ-LV1)

You need to install Gowin's official FPGA design software, Gowin EDA, which includes synthesis, place-and-route, and programming tools. After writing your design in Verilog or VHDL within the IDE, you generate a bitstream file. Connect the board via its onboard USB port, and use the software's programmer utility to flash the bitstream directly through the integrated USB-JTAG interface, configuring the FPGA's logic.

The board features a dedicated FPC (Flexible Printed Circuit) connector. You will need a compatible RGB LCD module with a matching FPC cable. Connect it directly to the onboard connector. Then, in your FPGA design, you must implement the appropriate display controller IP or write HDL code to drive the LCD's RGB data, sync, and clock signals using the I/O pins routed to that connector, referencing the board's pinout diagram.

Yes, the WSON8 pad is designed for attaching an external serial Flash memory chip, such as a 25-series SPI Flash. You would need to solder a compatible WSON8 package chip onto the pads. In your FPGA design, you must then instantiate a SPI controller IP core or write HDL to communicate with this external memory, allowing you to store additional configuration data, firmware, or application assets beyond the internal 128Kb flash.

The two tactile buttons are connected to general-purpose I/O pins of the FPGA, allowing you to define them as inputs for user control, reset signals, or mode selection in your design. The RGB LED is also connected to FPGA pins; you can implement a PWM controller in your HDL code to drive its red, green, and blue channels independently, creating status indicators, debugging visual outputs, or dynamic lighting effects for your project.
