Bambu Lab AP Board - HV for X2D

The Application Processor Main Board, or AP Board for short, is the circuit board that manages all internal communication and system-level processing for the printer. It provides an independent operating environment—handling things like memory management, firmware operations, graphics processing, multimedia decoding, Wi-Fi, camera signals, LEDs, and the user interface. This is the HV variant, intended for 220V printers. After replacement, the new serial number is not yet registered, so binding cannot be performed on first startup; skip the binding process to test the printer, then register the new SN through the Bambu Lab website or customer service.
