Bambu Lab TH Board - H2S

The Bambu Lab TH Board – H2S is a genuine OEM replacement for the main electronic board inside the H2S toolhead. It coordinates several critical toolhead components, including the hotend, extruder, cooling fan, and filament cutter, allowing them to operate together reliably during printing.

Replace the TH Board when diagnosing confirmed board damage, damaged connectors, electrical faults, or persistent toolhead errors that are not caused by the individual hotend, extruder, fan, or cutter components themselves.

This replacement includes the TH Board and four BT2.6-8 mounting screws. It is compatible with both the Bambu Lab H2S and H2S Laser.
