Gemini V3

Product Features

Onboard computer, can replace Raspberry Pi as the host computer to run, it has 1GB of onboard DDR3 memory.
Enhanced 5v power protection, reducing the possibility of chip damage.
Cancelled the storage card setting of the MCU chip, making it easier to flash firmware.
The system is pre-installed with klipper, moonraker, mainsail, fulidd, klipper-screen, Crowsmest, resonance compensation plugin numpy and FLY-Tools, no need for complex operations such as changing sources, easier for beginners to get started (need to purchase TF card or M2WE)

CPU: High-performance Allwinner H5 chip, 4-core 64-bit Cortex-A53
GPU: High-performance 6-core Mali 450, pixel fill rate greater than 2.7gpixel/s
RAM: 1GB DDR3 (shared with GPU)
ROM: Supports up to 128GB SDCARD
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, can expand WIFI, eMMC, etc. (Private protocol, do not connect non-FLY π dedicated M.2 devices)
Supports 12-24V DC power supply, more stable power supply, eliminates the need for a step-down module
Reserved a 5V controllable fan interface, which can be used for host computer cooling
Reserved CAN expansion interface
