What does the Holybro Remote ID module do?
The module broadcasts your drone ID, position, altitude, and velocity in flight over WiFi and Bluetooth. It uses the Open Drone ID framework in ArduRemoteID firmware.
It takes position data from the flight controller over CAN or serial. It has no GPS of its own, so the flight controller must feed it a fix.
The radio is FCC and CE certified as a radio module. That certification covers the radio, not FAA Remote ID compliance.
Which flight controllers work with it?
The module works with PX4 and ArduPilot flight controllers. ArduPilot supports Remote ID from version 4.3, and PX4 from version 1.14.
Holybro lists the Pixhawk 6C as a compatible controller. Any PX4 or ArduPilot board with a free CAN or TELEM port can host it.
Check your firmware version before you order. An old ArduPilot build without Remote ID support will not feed the module.
How do you wire it to the flight controller?
Wire the 4-pin CAN port to a DroneCAN port, or wire the 6-pin TELEM port to a serial port. The module takes 5V from either port.
Set the flight controller port for Remote ID traffic. ArduPilot documents the CAN and serial setup in its Remote ID guide.
Keep the antenna clear of carbon and metal. A blocked antenna cuts the broadcast range, which the manual lists above 500m.
Is this module FAA approved for end users?
No, not as a plug-and-play broadcast module. Holybro states it is a Standard Remote ID solution for manufacturers and integrators.
Holybro states USA users must do their own FAA Declaration of Compliance submission. The QRC listing states the same warning.
No FAA Declaration of Compliance entry for this module as an end-user broadcast module could be verified. Check the FAA DOC list before you fly with it.
When should you pick a different module?
Pick an FAA-accepted broadcast module when you need a plug-and-play retrofit for an older drone. Check the FAA DOC list for accepted modules.
Pick the Holybro module when you build a Standard Remote ID aircraft as a manufacturer or integrator with a DoC plan.
Pick a FRIA flight area when your drone has no Remote ID and you fly for recreation. A FRIA needs no module at all.
How the options compare
| Remote ID option | Who it fits | FAA path | Needs |
|---|---|---|---|
| Holybro module | PX4 and ArduPilot builders | Own DoC submission | CAN or serial port |
| FAA-accepted broadcast module | Older drone owners | DOC listed, enter serial | Mount and power |
| Built-in Standard Remote ID | New drone buyers | DOC listed by maker | Nothing to add |
| FRIA flight | Recreation pilots | Fly inside a FRIA | FRIA site access |
