Introduction

FLY C8

Product Features​

  • Uses a 32-bit ARM Cortex-M0+ series STM32F407VGT6 main control chip with a frequency of 168MHz
  • Equipped with TMC drivers in SPI and UART working modes
  • Equipped with a DIAG function pin, enabling zero-point homing by simply plugging in a jumper cap
  • Digital fan with selectable voltages of 24V, 12V, and 5V, eliminating the need for a voltage drop module
  • New Flash writing method, allowing direct firmware updates for the main board via FLY-Tools
  • Multi-channel power management; if ports, limit switches, or drivers short circuit, it will not affect the host machine operation *预留RGB接口支持（12V，5V）电压可选
  • Reserved SPI interface, allowing customers to connect external acceleration sensors for acceleration compensation
  • Support for one-wire connection between TFT screen and HDMI screen
  • The system pre-installs klipper, moonraker, mainsail, fulidd, klipper-screen, Crowsmest, resonance compensation plugins numpy and FLY-Tools, without the need for complex operations like changing sources, making it easier for beginners (requires purchasing an TF card or M2WE)
