ND-Pi turns a Raspberry Pi into an NDI & RTSP multiview switcher you cut live from the lighting desk over DMX. One binary set runs on both the Pi 5 (dual HDMI, higher source ceiling) and the Pi 4 (headless, NDI program out) — the app detects the model and sets its own limits.
Download the appliance bundle, then follow the guide. It is a technical setup — you supply the Pi and install the free NDI runtime yourself — and the full, illustrated step-by-step lives in the PDF.

Pi 5 vs Pi 4. The Pi 5 (recommended) drives dual HDMI — program + multiview — and carries more live sources; the Pi 4 runs headless (NDI program out, no HDMI) with RTSP capped. You do not pick a profile: the app self-reports its model and sets its own limits. Bring your own Pi, install the free NDI runtime yourself, and this is a technical setup — if you would rather it arrive ready to run, the Ready-to-Run Unit ships pre-loaded and configured.
