FLY-Pi Host Board

  • We are excited to release the new FLY-π board. This board can replace a Raspberry Pi as a host board, featuring 1GB of onboard DDR3 memory.
  • This host board can run Klipper and RRF firmware, and can even run the Klipper screen when using an SHT tool board.

Key Highlights​

  • Powerful Core, Deep Optimization: Equipped with the Allwinner H5 quad-core processor and preloaded with deeply customized FlyOS & Klipper firmware, delivering significantly improved instruction processing and motion planning performance compared to stock systems.
  • Dual Storage Options, Flexible Choices: Offers onboard M2WE interface (for FLY custom modules) and a standard Micro SD card slot, allowing users to choose between high-speed eMMC or cost-effective and flexible SD card solutions as needed.
  • Out-of-the-Box Experience, Complete Ecosystem: The system comes with all necessary plugins pre-installed (such as environments required for input shaping and resonance compensation), greatly reducing debugging time and enabling rapid printing deployment.
  • Industrial-Grade Design and Power Supply: Supports 12-24V wide voltage input, features a dedicated SPI accelerometer interface, ensuring long-term stable and reliable operation.
  • Rich Interfaces, Full Expansion: Provides multiple display outputs (HDMI, TFT), 4 USB 2.0 ports, Ethernet port, and CAN bus interface to meet various peripheral device connection needs.
  • Easy Maintenance with OTA Support: Supports one-click over-the-air (OTA) system updates, allowing users to obtain the latest features and security patches without reflashing the system.

Purchase and Usage Notes​

Important: About Storage

The FLY-Pi does not come with any storage device from the factory. You must prepare at least one of the following storage media yourself for the device to function properly:

  • Option 1 (Recommended): Purchase the FLY custom M2WE module (Wi-Fi/eMMC) for faster system response and higher reliability.
  • Option 2: Provide your own Micro SD (TF) card, with a recommended capacity between 16GB-128GB.

    Configuration Note

    This function requires manual configuration and enabling within the system; it is disabled by default at the factory.

5. System and Software​

  • Operating System: FlyOS-FAST (a lightweight system deeply optimized for 3D printing)
  • Core Firmware: Deeply optimized Klipper firmware & native support for RRF
    • Optimization Note: We have carried out low-level optimization and adaptation of Klipper, achieving significant improvements in command processing and motion planning performance compared with the original version.
  • Pre-installed Software:
    • Core: Klipper, Moonraker
    • Web Interface: Mainsail, Fluidd (Fluidd by default)
    • Functional Plugins: Essential plugins and environments such as input shaping and resonance compensation are pre-installed.
    • Optional Features: Klipper-Screen (touchscreen) and Crowsnest (camera) support are integrated and disabled by default.

Important Notes​

Interface Conflict Warning

The TFT screen, SPI accelerometer interface, and RRF expansion interface cannot be used simultaneously!

  • Hardware Conflict: The above interfaces physically share the same set of SPI resources.
  • Consequences: Connecting them simultaneously will result in abnormal screen display and severe accelerometer data errors.
  • Solution: Connect and use only one of these interfaces at a time.
M2WE Interface Warning

Proprietary protocol - connecting non-FLY devices is strictly prohibited!

  • The onboard M2WE interface uses a FLY proprietary custom protocol, with both physical and electrical specifications being non-standard.
  • Only connect the officially provided FLY M2WE module (Wi-Fi / eMMC).
  • Strictly prohibited from connecting any standard or third-party M.2 devices, as this will cause permanent hardware damage to the board.
About Wi-Fi Functionality

The FLY-Pi has no onboard Wi-Fi.

For wireless connectivity, please choose:

  1. Recommended Solution: Use the official FLY M2WE Wi-Fi module.
  2. Alternative Solution: Use a driver-free universal USB Wi-Fi module, ensuring it is compatible with Linux systems.
