## Description

KM-64 ROYGBIV — Premium, Seamlessly Tileable 8x8 RGB LED Matrix
---------------------------------------------------------------

Bring your retro-computing projects, custom displays, and hardware prototypes to life with the **KM-64 ROYGBIV (Rev. 1.0)**. Proudly **Designed in Italy**, this high-density 8x8 RGB LED matrix module effortlessly combines robust industrial engineering with a clean, striking aesthetic.

Whether you are building a standalone visual indicator, replicating classic hardware layouts, or tiling multiple units together to form a massive custom LED wall, the KM-64 ROYGBIV delivers flawless performance and perfect alignment without the "pixel bleeding" typical of cheap, monoblock alternatives.

### Key Technical & Design Features

*   **Seamlessly Tileable Architecture:** Engineered with a compact, square form factor (approx. 5x5 cm / 1900 mil) and edge-to-edge spacing. You can perfectly align multiple modules side-by-side or stack them vertically to create scalable, gapless retro-displays or scrolling message boards.
*   **64-LED High-Intensity Array:** Features 64 precision-spaced, 5mm diffused cylindrical RGB LEDs that guarantee smooth color blending, excellent contrast, and wide viewing angles.
*   **Common Cathode Matrix Design:** Organized into an efficient multiplexed grid utilizing 8 dedicated cathode lines (K1–K8) mapped across Red (R1–R8), Green (G1–G8), and Blue (B1–B8) anode channels for absolute pixel control.
*   **Integrated Protective Backing Frame:** The bottom assembly features a precision-fitted, custom black frame designed to shield the delicate solder joints and internal routing from mechanical stress and accidental electrical shorts.
*   **Solid Brass Interface Pins:** Equipped with heavy-duty, custom-pinned brass interface contacts on the reverse side, ensuring rock-solid electrical conductivity, low contact resistance, and long-term durability.
*   **Clear Silkscreen Pin Mapping:** The back of the PCB features crisp, detailed labeling for every single pin, making manual wiring, debugging, and microcontroller integration incredibly straightforward.

### Optoelectronic & Electrical Specifications

Every single RGB LED in the 8x8 array is engineered for consistent brightness and color purity under multiplexed drive conditions:

*   **Architecture:** Common Cathode matrix configuration.
*   **Maximum Operating Current:** 20mA maximum per color channel under PWM (Pulse Width Modulation) control.
*   **Red (R) Channel:** Wavelength: 620 – 625 nm | Forward Voltage (VF): 1.8 – 2.0 V
*   **Green (G) Channel:** Wavelength: 515 – 525 nm | Forward Voltage (VF): 3.2 – 3.4 V
*   **Blue (B) Channel:** Wavelength: 464 – 475 nm | Forward Voltage (VF): 3.2 – 3.4 V

### Available Options

*   **Full DIY Kit:** Includes the high-quality KM-64 PCB, 64 diffused 5mm RGB LEDs, 32 solid brass pins, and the custom protective backing frame. Perfect for makers who want the full assembly experience.
*   **Fully Assembled & Tested :** Ready out of the box. Every single component is hand-soldered with geometric precision, fully cleaned, and rigorously tested to meet industrial standards before shipping.
