Our custom DJI dropper system, servo driven, triggered by the drones on-board under light, carries 1 or 2 items. Fully built by us and code written by us so custom logic/triggers available on request.

Overview

The Firefly DJI Dropper gives commercial DJI platforms a reliable, controllable release mechanism for carrying and releasing small items. It is designed, built and programmed entirely in-house, so we control every part of it, from the mechanics to the firmware, and can change either to suit your requirements.

It is compact, light and quick to fit, so a standard DJI airframe becomes a delivery platform without permanent modification.

Key Features

Servo driven release: Positive, repeatable mechanical release.
1 or 2 item capacity: Carry a single item or two, released independently.
Triggered by the under-light: Uses the drone’s on-board under-light as its trigger, with no separate transmitter channel needed.
Custom logic and triggers: Because we write the code, release behaviour can be tailored on request, for example sequenced or conditional releases.
Designed and built by Firefly: UK built hardware and in-house firmware, with no dependence on third party dropper products.
Lightweight and compact: Minimal effect on flight time and handling.
Easy to fit and remove: Mounts to the airframe for quick installation.
