New controller for RTX 5080 AORUS MASTER 16G (GV-N5080AORUS M-16GD) with per-LED fan ring control. This GPU uses a different protocol than legacy RGB Fusion 2 cards and requires a separate controller. Hardware info: - PCI Device ID: 0x2C02 (NVIDIA Blackwell) - Subsystem ID: 0x4178 - I2C Address: 0x71 LED configuration: - 3 fan rings × 8 LEDs each = 24 fan LEDs - 1 logo LED - Total: 25 individually addressable zones Protocol details (reverse engineered from Gigabyte Control Center on Windows): - Mode command (0x88) must include zone selector byte (0x02/0x05/0x06) - Each fan requires mode command before color registers will respond - Color registers: 0xB0-0xB3 (left), 0xB4-0xB7 (middle), 0xB8-0xBB (right) - Logo: 0xBC with mode byte 0x00 (fans use 0x01) - Apply command (0xAA) must be sent after each zone for multi-zone updates Verified working on Linux with i2ctransfer and OpenRGB CLI: - All 24 fan LEDs individually addressable - Logo LED working - Color cycling and per-LED gradients tested Note: Fan LEDs only illuminate when fans are spinning.
