Product Introduction

The Fly-MMU Multi-Function Tool Board is a high-performance control board specifically designed for 3D printers and automation equipment. It integrates a powerful H723 microcontroller, supports up to 4 TMC stepper motor drivers, and features high-voltage drive capability. It comes with 11 limit switch inputs onboard and can be expanded to 16 limits via an FPC connector, along with 4 servo control outputs. This tool board is compatible with Klipper firmware and offers CAN bus and RS232 connection options for flexible communication and control solutions.
