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 is compatible with high-voltage drivers. It comes with 11 limit switch inputs onboard and can be expanded to 16 limits via FPC, along with 4 servo control outputs. This tool board is compatible with the Klipper firmware and offers CAN bus and RS232 connectivity options for flexible communication and control solutions.
