YTYIN UV LED Board for ELEGOO Mars 2 & Mars 2 Pro
Where to Buy
Description
A light panel for the LCD stack of the original Mars 2 machines. After five or six years the emitter fades: prints get unpredictable, supports snap off the plate, and more exposure just blows out fine detail. YTYIN builds this board — an aftermarket maker, not ELEGOO. It uses a plug instead of soldered leads and carries a thermistor next to the emitter.
Specifications
- COB emitter on a metal-core PCB
- Seller-stated wavelength of 385 nm
- NTC thermistor soldered next to the emitter
- Multi-pin connector instead of soldered leads
Compatibility: ELEGOO Mars 2 and Mars 2 Pro, both built around a 6.08" 2K panel. One caveat: both printers ship with a 405 nm light engine, but this seller lists the board as 385 nm. Confirm the wavelength and the connector before you pay — a different wavelength means recalibrating every exposure, and 405 nm resins may behave differently. It's the only listing on offer, and pricier than boards for newer models.
