Gemini V2 All-in-One 3D Printer Control Board
Loading...
Product Overview
The Gemini V2 is a 3D printer control board that integrates both a host and a secondary MCU. It features an onboard Allwinner H5 host and an STM32F405 secondary MCU, allowing it to run the Klipper environment directly and eliminating the need for an external host and data cable connections.
Product Features
- All-in-One Design: Features an onboard Linux host and STM32 secondary MCU, capable of running Klipper directly.
- RAM: The Gemini V2 is upgraded to 1GB DDR3, enabling simultaneous use of CAN and KlipperScreen.
- Expandable Storage: Supports Micro SD cards and can be expanded with WiFi or eMMC modules via the FLY-specific M.2 interface.
- Peripheral Interfaces: Supports common interfaces such as USB, Micro HDMI, Ethernet, SPI, and UART.
- Driver Interface: Provides 4 high-voltage driver sockets, supporting TMC driver UART/SPI modes.
