Gemini V3 Integrated 3D Printer Control Board

Loading...

Product Overview​

The Gemini V3 is a highly integrated, all-in-one control solution featuring an embedded host computer. Its onboard high-performance computing core can directly replace a standalone host computer like a Raspberry Pi. It integrates 1GB of DDR3 memory and incorporates an enhanced 5V power protection design, significantly improving system reliability and stability.

Storage Device Notice

The Gemini series does not include storage devices by default. You will need to prepare one of the following storage media to install and run the system:

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

Key Features​

  • All-in-One Design: Features an onboard Allwinner H5 host computer with integrated 1GB memory, eliminating the need for an external Raspberry Pi, simplifying wiring, and reducing costs.
  • Enhanced Reliability: Optimized 5V power circuit protection effectively reduces the risk of chip damage caused by voltage anomalies.
  • Out-of-the-Box Experience: The system image comes pre-installed with the complete Klipper ecosystem software (including Moonraker, Mainsail, KlipperScreen, etc.) and common plugins, eliminating complex configuration and significantly lowering the entry barrier for beginners (requires a self-provided storage device).

Important Parameters and Safety Notes​

Port Output Current Capabilities​

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

Output PortMaximum Current at 24VMaximum Current at 12V
Heated Bed Port15 A7.5 A
Heater Cartridge Port6 A3 A
Fan Port1 A0.5 A

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