USB
| Item | Specifications |
|---|---|
| Type‑C | 1 × Type‑C power supply / charging / data interface. Supports fast charging via the USB‑PD protocol (a charger that supports USB‑PD must be used); can be used for data functions such as file transfer, USB tethering, MIDI, and PTP. Connecting the Type‑C interface to a computer is recommended only for officially specified upgrade / maintenance or debugging scenarios |
| USB‑A | 1 × USB 3.0 (if configured), used to connect USB flash drives, debugging tools, and other USB peripherals (exFAT format is recommended for USB flash drives) |
Display and Interfaces
| Item | Specifications |
|---|---|
| HDMI | 1 × HDMI 2.0, maximum output resolution of 1080p, with synchronized audio and video output (see Section 5.4 for usage instructions) |
| 3.5 mm PPM interface | Used for conventional PPM remote-control signals and similar purposes (whether it is enabled and its specific usage are subject to the product specification sheet and supplied documentation) |
Storage Expansion
| Item | Specifications |
|---|---|
| microSD card slot | 1 slot, supporting common microSD/SDHC/SDXC specifications; Class 10 or higher speed rating recommended |
Network and Communication
| Item | Specifications |
|---|---|
| Ethernet | 1 × RJ45 Ethernet port, supporting configurations such as static IP and DHCP; actual link speed is subject to measurement |
| nano‑SIM card slot (No. 45) | 1 × structurally reserved slot; no cellular/mobile network functionality; do not insert a SIM card (see Chapter 2, Regulations and Compliance Statement, for details) |
| PPM/other interfaces | Depending on the specific model, expansion interfaces such as PPM and serial ports are provided for integration with a flight controller or other devices |
Expansion and Compatibility
- Various data link or data transmission modules can be connected through the expansion bay and data link interfaces;
- The USB‑A interface can be used to connect storage devices, debugging tools, or certain human-machine interaction peripherals (such as a mouse or keyboard, depending on firmware support). USB‑A is generally preferred for routine data transfer; Type‑C is primarily used for power supply / fast charging via the USB‑PD protocol and can also serve as a supplementary data and upgrade interface when needed;
- Interfaces such as HDMI and Ethernet make it easy to connect to existing command systems and display systems.
For recommended cable specifications and adaptation methods, refer to Chapter 1, Quick Overview of Key Specifications, together with the related instructions under “Display and Touchscreen / HDMI Output” in this chapter.
