FLY-C5 Mainboard Overview

Product Features​

  • 32-bit ARM Cortex-M4, 550MHz, STM32H723VGT6 chip
  • Supports TMC-driven SPI, UART, STEP/DIR working modes
  • DIAG function pin does not occupy limit switches; after configuration, it can achieve homing without limit switches
  • Digital control fans support 24V, 12V, 5V, no additional voltage drop module required
  • Supports power-off auto shutdown and power-off resume printing (power-off auto shutdown is enabled by default)
  • Pre-installed USB Klipper firmware at factory
  • Multi-channel power management, short circuits on ports, limit switches, and drivers do not affect host machine operation -预留 5V RGB interface
  • TFT and HDMI screens support one-line connection
  • System pre-installs klipper, moonraker, mainsail, fulidd, klipper-screen, Crowsmest, resonance compensation plugin numpy, no need to change source, easy to use (TF card or M2WE purchase required)
