Gemini V3 All-in-One 3D Printer Control Board

Loading...

Product Overview​

The Gemini V2 is a highly integrated all-in-one control solution with an onboard host. Its high-performance computing core can directly replace standalone hosts like the Raspberry Pi. It integrates 1GB of DDR3 memory and, combined with an enhanced 5V power protection design, significantly improves system reliability and stability.

Storage Device Notice

The Gemini series does not include a storage device by default. You need to provide one of the following storage media to install and run the system:

  1. Recommended Option: Purchase a dedicated FLY M2WE module for faster system speeds and higher reliability.
  2. Alternative Option: Use a Micro SD (TF) card with a capacity between 16GB and 128GB.

Core Features​

  • All-in-One Design: Features an onboard Allwinner H5 host, integrated 1GB memory, eliminating the need to purchase and connect a separate Raspberry Pi, simplifying wiring, and reducing costs.
  • Enhanced Reliability: Optimized 5V power circuit protection effectively reduces the risk of chip damage due to voltage abnormalities.
  • Ready to Use: The system image comes pre-installed with a complete Klipper ecosystem (including Moonraker, Mainsail, KlipperScreen, etc.) and common plugins, eliminating complex configurations and significantly lowering the entry barrier for beginners (requires your own storage device).

Important Parameters & Safety Notes​

Port Output Current Capability​

The maximum output current for each port varies with the supply voltage (12V or 24V). Please strictly refer to the table below when configuring your devices and ensure the power supply has sufficient capacity.

Output PortMax Current @ 24V SupplyMax Current @ 12V Supply
Heated Bed Port15 A7.5 A
Hotend Heater Port6 A3 A
Fan Ports1 A0.5 A

Note: It is recommended to plan for sufficient power headroom for loads operating near the current limits (especially the heated bed) and ensure all wiring connections are secure to avoid overload risks.
