Overview

FLY C8

Uses ARM Cortex-M0+ series STM32F407VGT6 main control chip with a 32-bit architecture and 168MHz main frequency
Supports SPI and UART working modes of TMC drivers
Onboard DIAG function pin, allows easy use of endless limit homing by simply plugging or removing a jumper cap
CNC fan with selectable 24V, 12V, or 5V voltage options, eliminating the need to purchase a buck module
New Flash writing method, allows direct firmware updates via FLY-Tools
Multi-channel power management; short circuits in ports, limit switches, or drivers won't affect the host computer's operation *预留RGB接口支持（12V，5V）电压可选
Reserved SPI interface for connecting external accelerometers for acceleration compensation
TFT screen and HDMI screen support single cable connection
System pre-installed with klipper, moonraker, mainsail, fulidd, klipper-screen, Crowsmest, resonance compensation plugin numpy, and FLY-Tools; no need for complex operations such as switching sources, easier for beginners to get started (requires purchase of TF card or M2WE)
