FLY-Pi V3 Host

The FLY-Pi V3 is a standard-sized host computer with a form factor compatible with the Raspberry Pi, designed to provide a stable and powerful computing core for professional-grade 3D printing. It not only serves as a perfect replacement for the Raspberry Pi but also, with its deeply optimized Klipper system, industrial-grade interfaces, and flexible storage expansion options, helps you unlock a faster, more precise, and more reliable printing experience.

Core Highlights

• Deep Optimization, Performance Leap: Equipped with an Allwinner H618 quad-core processor and pre-installed deeply customized FlyOS & Klipper firmware, offering significant improvements in processing efficiency and printing performance compared to the native versions.
• Flexible Storage, Configure as Needed: Features an onboard dedicated M2WE interface, supporting the FLY custom M2WE module (Wi-Fi/eMMC), providing you with a high-speed system boot option.
• Ready-to-Use, Complete Ecosystem: The system comes pre-configured with all essential plugins, eliminating complex debugging and significantly reducing the time from installation to the first print.
• Industrial-Grade Design, Stable and Reliable: Offers 12-24V wide-voltage power input, power-loss shutdown protection, and a dedicated SPI accelerometer interface, ensuring long-term stable operation.
• Rich Interfaces, Worry-Free Expansion: Multiple display outputs, multiple serial ports, and an RRF expansion interface meet various peripheral connection needs.
• One-Click Updates, OTA Support: Supports one-click system updates, allowing you to easily obtain the latest features and security patches without re-flashing the system.

Purchase and Usage Notes

Important: Regarding Storage

The FLY-Pi V3 does not come with any storage device (i.e., it does not include an M2WE module or a Micro SD card). You must configure at least one of the following storage media for the device to function:

• Option 1 (Recommended): Purchase the FLY custom M2WE eMMC module for faster system response and higher reliability.
• Option 2: Prepare your own Micro SD (TF) card (maximum support 128GB).

  • Advanced Feature Plugins: Essential plugins like Input Shaping and Resonance Compensation are pre-installed (numpy is pre-installed, no additional configuration needed).

Important Notes

Interface Conflict Warning

TFT Screen and SPI Accelerometer Interface CANNOT be used simultaneously!

• Physical Conflict: The TFT screen (via the FPC-TFT interface), the SPI accelerometer interface (ZH1.5-7P), and the RRF expansion interface share the same set of SPI resources on the hardware.
• Consequence: If connected simultaneously, it will cause abnormal screen display and severely inaccurate accelerometer measurement data.
• Solution: Ensure only one of them is connected during use.

M2WE Interface Warning

Proprietary Protocol, Strictly Prohibit Connecting Non-FLY Devices!

• The onboard M2WE expansion interface uses a FLY proprietary protocol, with both physical and electrical specifications being custom.
• Only supports connection of the officially provided FLY M2WE module (for expanding Wi-Fi or eMMC storage functionality).
• Absolutely prohibit connecting any standard or unofficial M.2 devices, as this will inevitably cause permanent hardware damage to the mainboard.

Regarding Wi-Fi Functionality

The FLY-Pi V3 does not have onboard Wi-Fi.

If you need Wi-Fi, you have two options:

1. Recommended Solution: Purchase and use the FLY official M2WE Wi-Fi module.
2. Alternative Solution: Use a generic USB Wi-Fi module, but be sure it supports Linux systems and is driver-free to ensure compatibility.
