Tang Nano 9K FPGA Geliştirme Kartı GOWIN GW1NR-9 RISC-V HDMI

Introduction

The Tang Nano 9K, powered by Gowin's GW1NR-9 FPGA chip, is a versatile and feature-rich development board. It features several often used connectors, including HDMI, RGB screen, and SPI screen interfaces, aswell as a 32Mbit SPI flash and six LEDs. It has 8640 LUT4 logic units, an onboard 27MHz clock and 2 PLLs meaning, as well as basic FPGA designs, it can also be used for full risc-v softcores such as PicoRV.

Attention and Best Practices

• Troubleshooting: If you encounter any issues, consult our Tang Questions page first.
• Avoid using JTAG, MODE0/1, and DONE pins unless necessary. For details, refer to SUG100-2.6E_Gowin Software User Guide.pdf.
• Static Electricity Precautions: Always discharge static electricity before handling the PCBA to prevent damage.
• GPIO Voltage Compliance: Ensure that the actual working voltage of GPIOs does not exceed their rated value as indicated in the schematic. Exceeding these limits can cause permanent damage to the PCBA.
• FPC Cable Connection: When connecting FPC flexible cables, ensure that the cable is fully inserted into its base without any offset.
• Avoid Short Circuits: Prevent liquids or metals from coming into contact with the component pads on the PCBA while it's operating, as this could cause a short circuit and damage the PCBA.
• Handling Multiplexed IO and HDMI Ports: Be aware that the HDMI IO ports are pulled up. When using IOs routed to pin headers, they may not operate as intended.
