Gemini V3

Product Features

Onboard host computer can replace Raspberry Pi as the host computer, with 1GB of onboard DDR3 memory.
Enhanced 5V power protection reduces the possibility 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, and numpy are preinstalled in the system. No complicated operations such as changing sources are needed, making it easier for beginners to get started (TF card or M2WE needs to be purchased).

CPU: High-performance Allwinner H5 chip, 4-core 64-bit Cortex-A53
GPU: High-performance 6-core Mali 450, pixel fill rate greater than 2.7 Gpixels/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 Wi-Fi, eMMC, etc. (private protocol, do not connect non-FLY π dedicated M.2 devices)
Supports 12-24V DC power supply for more stable power, eliminating the need for a step-down module *预留了一个5V可控风扇接口，可用于上位机散热 *预留CAN扩展接口
