01/Product Overview
The CORVON RID is an add-on unmanned aircraft Remote ID broadcast module. It attaches to the airframe and connects to the flight controller with a single cable. The module obtains the aircraft's identification and position data from the flight controller and continuously broadcasts identification reports via Bluetooth, allowing any compliant receiving terminal, including a mobile app, to identify the aircraft in flight.
No flight-controller firmware or airframe modification is required: attach the module and connect one cable.

Product Features
- Add-on design: no change to the existing flight controller or airframe; installs with 3M adhesive and one GH1.25 cable to the flight controller.
- U.S. and EU modes on one hardware platform: the broadcast mode is preset at the factory for the variant you order.
- 11.2 g, 38 × 23.5 × 9 mm, CNC aluminum-alloy enclosure.
- Broadcasts at power-on: does not rely on a command from a ground station; broadcasting starts when powered.
- Configurable with a phone: built-in Wi-Fi configuration page opens in a browser; no dedicated software or driver is required.
- One-time identity lock: after locking, the identifier is read-only to prevent tampering.
- Signed OTA: online upgrade packages must carry a CORVON signature; writing is rejected if verification fails.

04/Interface Definition
| Interface | Pinout | Function |
|---|---|---|
| CAN (GH1.25 4-pin) | 1 = 5V · 2 = CAN-H · 3 = CAN-L · 4 = GND | Connects to the flight-controller CAN port (DroneCAN); pin order matches the DroneCAN standard JST-GH connector. |
| UART (GH1.25 4-pin) | 1 = 5V · 2 = RX · 3 = TX · 4 = GND | Connects to a flight-controller serial port (MAVLink); default 57600 bps. Pin 1 is the 5 V supply. Signals are 3.3 V TTL: connect directly to the flight-controller serial port; do not connect to a 5 V logic serial port. RX / TX are named from the module side: module TX to flight-controller RX, module RX to flight-controller TX. |
| USB-C | — | Configuration and firmware flashing; driver-free. |
| MMCX | — | RF output; connects to external antenna RID-ANT-01. |
05/Broadcast Modes
| Variant | Transport | Broadcast Content |
|---|---|---|
| US | Bluetooth 4 + Bluetooth 5 Long Range | ASTM F3411 Remote ID message set |
| EU | Bluetooth 4 + Bluetooth 5 Long Range | Remote ID message set + EN 4709-002 operator registration number |
Both variants use the same hardware; the broadcast mode is preset at the factory for the variant ordered.
06/Antenna Installation Requirements
The antenna is external, and its installation location directly determines whether ground reception is possible. Follow all three requirements:
- Install the antenna vertically, with the long edge of the antenna board upright.
- Mount it on a non-metallic, non-carbon-fiber surface.
- Keep metal and carbon fiber at least 10 mm away from the back of the antenna.
For a carbon-fiber airframe, route the antenna to a non-carbon-fiber location, such as the landing-gear cover or an antenna bracket, before attaching it.
07/Status Indicator
| LED Pattern | Meaning |
|---|---|
| Rapid red → green → blue sequence at power-on | LED self-test (once) |
| Dim white breathing | Booting (approximately the first 15 s) |
| Blue double flash (twice every 2 s) | No flight-controller data received. Check the cable and flight-controller serial-port settings. |
| Cyan breathing | Connected to the flight controller and waiting for a GPS fix (normal indoors). |
| Yellow breathing | Operating normally; identity not locked. |
| Green breathing | Operating normally; identity locked. |
| White flash at 1 Hz | Firmware upgrade in progress; do not power off. |
| Red triple flash | Fault. Power cycle once; if the red indication remains, contact after-sales service. |
