Important: About Storage

The FLY-C8P does not come with any storage device from the factory (i.e., it does not include an M2WE module or Micro SD card). You must configure at least one of the following storage media for the device to function properly:

• Option 1 (Recommended): Purchase the FLY customized M2WE module for faster system response and higher reliability.
• Option 2: Prepare a Micro SD (TF) card with a capacity between 16GB and 128GB.

Product Features

• Utilizes a 32-bit 550MHz Arm® Cortex®-M7 series STM32H723VGT6 main control chip
• Supports SPI and UART working modes for TMC drivers
• Onboard DIAG function pins, enabling endstop-less homing by simply plugging or unplugging jumper caps
• Digital fans support selectable 24V, 12V, and 5V voltages, eliminating the need for separate voltage step-down modules
• New Flash programming method allows direct firmware updates via command line
• Multi-channel power management; short circuits in ports, endstops, or drivers will not affect the host computer's operation
• Reserved RGB interface supports optional (12V, 5V) voltages
• TFT and HDMI screens support single-cable connectivity
• System pre-installs Klipper, Moonraker, Mainsail, Fluidd, Klipper-screen, Crowsnest, and resonance compensation plugin numpy, eliminating the need for complex operations like changing sources, making it easier for beginners
