The RTD2281-V1.0NI is a high-performance, multi-functional LCD AD controller board designed for 7.0-inch TFT LCD displays[cite: 7]. Powered by the Realtek RTD2281CL main chipset, this board converts HDMI video signals (supporting input resolutions up to 1920x1080 @ 60Hz) for 50-pin FPC screen interfaces[cite: 7]. It also features integrated analog audio input, 2x1.2W speaker outputs, onboard control keys, and flexible touch screen passthrough support (configurable for 4-wire resistive or 6-wire capacitive touch)[cite: 7]. Ideal for Raspberry Pi DIY projects, portable monitors, and industrial control interfaces[cite: 7].
Key Features
- Main Processor: Built on the Realtek RTD2281CL main chipset[cite: 7].
- Display Compatibility: Designed for 7.0-inch TFT LCD display panels (3.3V panel voltage / 50-pin FPC interface)[cite: 7].
- Video Signal Input: Mini-HDMI input (CN4) or optional 20-pin FPC HDMI interface (CN13), supporting input formats up to 1920x1080 @ 60Hz[cite: 7].
- Audio & Speaker Support: Includes PC analog audio input (3.5mm / 3-pin connector) and built-in speaker output (2x 1.2W @ 4Ω)[cite: 7].
- Touch Panel Passthrough: Integrated interfaces supporting either 6-wire capacitive touch (CN6 FPC) or 4-wire resistive touch (CN11 FPC) via USB passthrough[cite: 7].
- Flexible Power Supply: Powered via Type-C (+5V DC, CN1) or optional 4-pin 2.0mm connector (CN9) with standby power under 0.2W[cite: 7].
- Onboard Keys & OSD: Built-in SMD function buttons (Power, Menu, Up, Down, Exit) supporting multi-language OSD navigation[cite: 7].
