Elegoo Mars 4 Mainboard – Replacement Motherboard for Resin 3D Printer

Your Mars 4 won't boot. Screen's dead. Or it's throwing errors that no firmware reset will fix. You've already tried the obvious stuff, and now you're staring at a $169 machine doing nothing.

This is the mainboard that makes it all work. Straight swap into your Elegoo Mars 4. No reprogramming, no hunting for obscure drivers. Pull the old board, seat this one, power up, done.

$169 RRP. Cheaper than a new printer, and you keep the build plate, LCD, and resin tank you already have. Add to cart when you're ready to get back to printing
