Creality MF003 Interface V20 CFS 485 PCBA Module

Description

The Creality MF003 Interface V20 CFS 485 PCBA Module is a replacement circuit board designed for Creality’s Filament System (CFS) box. It acts as the hub for communication between the 3D printer and the multi‑filament box, using RS‑485 (or equivalent bus) to manage sensor data, filament switching, and system status. The board enables detection of filament presence, run‑out/tangle sensors, and interfaces with other PCBA modules in the CFS system. Its compact design and plug‑and‑play layout make it ideal for replacing a broken or faulty CFS interface board in printers like the K2 Plus Combo or Hi Combo. It ensures consistent communication, signal integrity, and modular upgradeability in multi‑filament setups.
