The CUAV C-RID from China is a Remote ID module for installation that runs on a dual-core processor of the ESP32 class and uses the open-source ArduRemoteID firmware. It offers DroneCAN and MAVLink interfaces and sits in an aluminium shell. That points to systems based on ArduPilot whose flight controller supplies position and operator data.
It transmits over Wi-Fi or Bluetooth on 2.4 GHz at 20 dBm, which equals 100 mW. The module has no GNSS receiver of its own; position comes from the flight controller. It weighs 15.5 g, more than board-only modules, and so clearly counts towards take-off weight on small drones. CUAV quotes a range of more than 300 m; it depends on the receiving device, the antenna and the surroundings and is no guarantee that the identification can be read in every situation.
In the EU a module must transmit to ASD-STAN EN 4709-002 and carry an EU declaration of conformity; US standards alone are not enough. Add-on modules for direct remote identification are governed by Part 6 of the Annex to Delegated Regulation (EU) 2019/945. The module has to accept the operator registration number and send serial number, time, position, altitude, course and speed as well as the pilot position or take-off point throughout the flight.
When choosing, the EU declaration of conformity counts, and it should be requested before buying. With a metal housing it matters that the aluminium does not shield the antenna. The ArduRemoteID firmware is under active development; updates and the correct parameters for operator ID and serial number should be checked before each season. The connectors for CAN and the serial port are the mechanical wear points.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Ask about parts availability for this build year — the running costs hang on it.
