Hotend Interface Board

The 2101020308 PCB acts as an adapter and breakout board within the K1 Series toolhead. It provides connection points between components such as the ceramic hotend heater, thermistor, cooling system and the printer's toolhead wiring, helping maintain reliable electrical communication within the printhead assembly.

Replacement for Toolhead Repairs

A damaged hotend adapter PCB can affect electrical connectivity within the toolhead and may contribute to heater, temperature-sensing or other hotend-related faults. The 2101020308 provides a genuine replacement board for compatible printer and hotend revisions.

Compatibility

• Creality K1 - compatible revisions
• Creality K1 Max - compatible revisions
• Creality K1 SE - compatible revisions
• Creality K1C - selected compatible revisions

Compatibility is dependent on the printer and hotend revision. Newer and older K1 Series toolheads can use different PCB connectors and adapter boards. In particular, certain 2025 K1C and K1 Max configurations use different part numbers. Confirm that the existing board is Creality part number 2101020308 and compare its connectors before replacement.
