Gemini V3

Product Features

Onboard host computer can replace Raspberry Pi as the host computer, with 1GB onboard DDR3 memory.
Enhanced 5V power protection, reducing the chance of chip damage.
Removal of the storage card setup for the MCU chip makes firmware flashing easier.
Klipper, Moonraker, Mainsail, Fluidd, Klipper-Screen, Crowsnest, resonance compensation plugin numpy, and FLY-Tools are pre-installed in the system. No complex operations such as switching sources are required, making it easier for beginners to get started (TF card or M2WE needs to be purchased).

CPU: High-performance Allwinner H5 chip, Quad-core 64-bit Cortex-A53
GPU: High-performance 6-core Mali 450, pixel fill rate greater than 2.7 Gpixel/s
RAM: 1GB DDR3 (shared with GPU)
ROM: Supports up to 128GB SD card
Peripherals: SPI x2, UART x2, USB x4 (USB 2.0 x3, OTG x1), Micro HDMI x1, Eth x1 (100M), CAN x1
Interface: Onboard M.2 interface for expandable WIFI, eMMC, etc. (Private protocol, do not connect non-FLY π dedicated M.2 devices)
Supports 12-24V DC power input for more stable power supply, eliminating the need for a step-down module
Reserved 5V controllable fan interface for host computer heat dissipation *预留CAN扩展接口
