Description
The Elegoo Saturn 4 Ultra Mainboard is an official OEM replacement motherboard engineered specifically to drive the high-precision processing and automated hardware systems of the Saturn 4 Ultra16K Series resin 3D printers.
Acting as the central control unit, this PCB coordinates high-resolution MIPI display output to the mono LCD screen, controls the COB light source and Fresnel collimating lens array, drives the Z-axis stepper motor, and manages the tilt-release mechanism. Additionally, it processes real-time telemetry from onboard smart sensors, internal AI camera modules, Wi-Fi transfer, and active cooling fans.
Features
Genuine Elegoo OEM Component: Direct factory replacement matching original mounting dimensions, socket layout, and firmware architecture.
Ultra-High Resolution Display Control: Built to drive high-density 10-inch 16K monochrome LCD screens over high-speed MIPI interfaces without signal latency or image distortion.
Tilt-Release & Motor Synchronization: Controls dual-axis motion sequences (tilt vat mechanism and Z-axis lead screw) for fast printing speeds up to 150 mm/h.
Integrated Sensor & Camera Interfacing: Native port connections for the AI camera feed, automatic self-check sensors, and resin shortage/force sensors.
Wi-Fi & Storage Integration: Onboard network chip supports high-speed wireless print file transfers and cluster printing management.
