General Ask
Do I need Wi-Fi?
No. It’s a direct point-to-point wireless HDMI link.
Does it work with iPhone?
Yes — iPhone 15 and newer via USB-C video out (adapter included). Older Lightning-port iPhones are not supported for video out.
Can it connect to cameras or Raspberry Pi?
Yes. Mini/Micro HDMI adapters are included for popular camera boards and compact devices.
Gaming?
Great for casual/party use and large-screen mirroring. For competitive gaming that demands 1:1 wired latency, a cable is still recommended.
