HD Cast + Wireless Video Extender
Cut the cable. Extend the screen. This reference covers PCB design + chipset kits for mirroring (cast) and TX/RX video-link modes, with multiple product form factors.
Phones, tablets, PCs, and HD sources connect wirelessly to TVs, projectors, and monitors—combining HD transport, stable links, multi-OS support, and flexible customization for meetings, home entertainment, and interactive teaching.
Highlights
Up to 1080P @ 60Hz · 5G Wi-Fi · plug-and-play · about 100–150 m in open space
1. Two operating modes
Cast / mirroring mode
Wirelessly mirror phone, tablet, or PC content to a TV, projector, or monitor.
- AirPlay (iOS / macOS), Miracast (Android / Windows), and DLNA
- Mainstream phone and PC brands
- P2P links without relying on a public network
- Media sharing, mobile office, classroom interaction, and demos
Video-link mode (wireless extender)
Use a paired transmitter (TX) and receiver (RX): the source connects to TX over HD or Type-C; the display connects to RX over HD.
- No app required after pairing
- One-to-one, one-to-many, and many-to-one
- More direct and stable than software-only casting for many setups
- Meetings, STBs, game consoles, media boxes, and professional HD wireless extension

2. Key features
Plug-and-play
Minimize pairing friction. Phones, tablets, notebooks, or HD sources can cast wirelessly without a third-party app. Switch between P2P video-link and phone mirroring.
1080P 60Hz, low latency
5G Wi-Fi module supports up to 1920 × 1080 @ 60Hz for slides, film, and motion content.
Interference-aware links
Automatic channel preference helps avoid congested bands and keep meetings or playback more stable in dense Wi-Fi environments.
Broad device coverage
iOS, Android, Windows, and macOS, plus AirPlay, Miracast, and DLNA. Sources include PCs, phones, consoles, STBs, and media boxes.
Compact forms, expandable SKUs
Portable housing with thermal design for long sessions. Expandable to:
- External stick-antenna variants
- Internal-antenna variants
- Type-C direct-plug variants
- LED status-display variants
