Product Introduction

The Fly-MMU multifunctional tool board is a high-performance control board designed for 3D printers and automation equipment. It integrates a powerful H723 microcontroller, supports up to 4 TMC stepper motor drivers, and supports high-voltage driving. It comes with 11 limit switch inputs and can expand to 16 limits via FPC, as well as 4 servo control outputs. This tool board is compatible with the Klipper firmware and offers CAN bus and RS232 connection options for flexible communication and control solutions.
