Introduction

Mellow Fly-D8 is a high-performance 3D printer motherboard launched by the Fly3D motherboard R&D team of Guangzhou Melun Electronics Technology Co., Ltd. It supports up to 8 stepper motors.

Product Features​

  • The motherboard's limit switch and other interfaces are powered by 5V with isolation protection. If the POWER supply is not connected, no power will be output.
  • Uses a 32-bit ARM Cortex-M4 series 168 MHz STM32F407 chip.
  • Supports CAN bus and RS232 connection for more stable data transmission, lower latency, and more stable connections.
  • The motherboard has BOOT and RESET buttons reserved for users to update firmware via USB in DFU mode.
  • The power interface has reverse polarity protection to prevent damage to the board during DIY when the power cable is connected incorrectly.
  • Provides two USB 2.0 ports, expanding more connection possibilities. One USB port can be switched to an RS232 port via a switch to adapt to various device connection needs.
