LIXIU Motherboard for ELEGOO OrangeStorm Giga

The main control board for ELEGOO's largest printer. Boards get replaced after a heater MOSFET cooks itself, after a shorted motor cable takes out a stepper driver, or after a failed firmware flash bricks the machine. LIXIU makes this one — ELEGOO doesn't sell the Giga mainboard at retail, only through service channels.

Specifications

• Stepper headers for X, Y and multiple Z axes
• Ethernet jack plus an external Wi-Fi antenna in the box
• Two USB-A ports, USB-C and a memory card slot
• 24 V screw terminal and MOSFET outputs for the heaters

Compatibility: ELEGOO OrangeStorm Giga. The board in this listing is silkscreened IGA-V3.0.7 — photograph yours and compare the revision and connector layout before ordering, since Giga units shipped with more than one. Plan on recalibrating after the swap: bed mesh, endstops and extruder settings all come back at factory defaults.
