No. Interface Name Function
①, ③, ⑪, ⑭ Vision Positioning Camera Interfaces Used to connect the standard positioning cameras
IMU Interface The reserved interface can be provided to the X86 computer for use as the IMU of the vision positioning system
RTK Data Serial Port Used to communicate with the RTK module; corresponds to ttyS5 on the onboard computer (available to both x86 and RK3588, with ttyS5 used for both)
Perception Data Output Serial Port Outputs positioning data (MAVLink protocol); corresponds to ttyS2 on the x86 computer
⑥, ⑨ USB3.0 Interfaces USB 3.0 interfaces on the x86 computer; support the DP protocol
⑦, ⑫, ⑳ Production Debug Interfaces Production debug interfaces. ⑫ also provides ttyS6 and ttyS7 for the gimbal
RK3588 Download Interface Reserved RK3588 image download interface for downloading firmware
Three-in-One Ethernet, Power, and Serial Interface The Ethernet port is used for x86 network communication; the serial port is used to communicate with the RK3588 (corresponding to ttyS6); the power cable supplies power to the FlyCore-U
Mission Payload Interface Provides MIPI, USB 2.0, and serial interfaces for connecting a mission payload to the perception and planning computer. A Heq custom dual-sensor, dual-axis miniature gimbal can be connected. Corresponds to ttyS7 and ttyS8 on the RK3588
Fan Interface Used to connect the x86 cooling fan
⑯, ⑲ Expansion Serial Ports External serial ports of the RK3588 that provide 3.3 V and 5 V power, respectively. ⑯ corresponds to ttyS3, and ⑲ corresponds to ttyS9
Expansion Ethernet Port External Ethernet port of the x86 computer that provides 12 V power externally
LiDAR Interface Used to connect a LiDAR
Coin Cell Battery Interface Used for the RTC battery of the onboard computer
