BIAONU UV LED Board for ELEGOO Saturn 2 & Saturn 8K

The light engine for the ten-inch Saturn machines. It gets swapped when a model that used to print flawlessly starts pulling off the plate and the corners of the build area come out undercured. If a pixel test shows a clean panel but prints still fail, the light source is the culprit. BIAONU makes this board — ELEGOO sells no original light engine.

Specifications

• 48-point COB emitter, 405 nm wavelength
• Sized for the 10" 8K panel shared by Saturn 2 and Saturn 8K
• Four mounting holes with vibration-damping grommets
• Tinned power leads ready for the driver terminals

Compatibility: ELEGOO Saturn 2 and Saturn 8K — the same platform with a 10" 8K panel and a 405 nm light engine. The Saturn 3 and Saturn 3 Ultra (12K) and the original 8.9" Saturn 4K each need their own board. If the light engine doesn't fire at all, check the driver board first — the emitter itself may be fine.
