Introduction

FLY C8

Uses the STM32F407VGT6 main control chip from the ARM Cortex-M0+ series with a 32-bit main frequency of 168MHz
Supports SPI and UART operation modes of TMC drivers
Onboard DIAG function pin allows unlimited homing with a simple jumper cap installation/removal
CNC fan with optional 24V, 12V, or 5V voltage eliminates the need to purchase a step-down module
New flash programming method allows direct firmware updates via FLY-Tools
Multi-channel power management ensures that short circuits in ports, limit switches, drivers, etc., will not affect the operation of the host computer *预留RGB接口支持（12V，5V）电压可选
Reserved SPI interface allows customers to connect external accelerometers for acceleration compensation
Supports one-cable connection for TFT and HDMI displays
System pre-installed with klipper, moonraker, mainsail, fulidd, klipper-screen, Crowsmest, resonance compensation plugin, and numpy, eliminating the need for complex operations such as changing sources, making it easier for beginners to get started (requires purchase of TF card or M2WE)
