We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.
Every autonomous decision the aircraft makes passes through one module. The aerial electronics system is the central processor — the board that takes position from GPS and RTK, attitude and motion from the inertial sensors, terrain and obstacle returns from the radar and sensing hardware, and commands from the remote controller, then turns all of it into coordinated instruction for propulsion and payload. When it works, the aircraft holds a line across a field and nobody thinks about the board that made it happen. When it fails, the symptoms almost never announce themselves as a mainboard problem. The aircraft throws sensor errors, will not accept a mission, loses RTK fix, reports components that test fine on the bench, or simply refuses to arm on a morning when the wind is finally right.
That is the economics this module exists to fix. An avionics failure does not ground one subsystem — it grounds the entire aircraft, along with the payload, the route plans, and the contract acres that were supposed to be covered this week. Replacing the electronics module returns the whole machine to service in a single defined bench job, instead of leaving a working sprayer parked while parts are chased one sensor at a time and the application window closes around it.
We use specialized technicians to deliver the DJI Agras Aerial Electronics System / Avionics Module ordered.
That is why Ares Acres keeps hard-to-find OEM avionics in stock and shipped fast to the U.S.A., helping operators return grounded aircraft to service, minimize downtime, and keep their sprayers flying when every acre counts.
For professional farmers, aerial applicators, and commercial drone operators, this module is the difference between an aircraft in the shop and an aircraft on the schedule.
The DJI Agras Original Aerial Electronics System / Avionics Module is the main flight control board for the aircraft — the central processor that coordinates flight, sensing, navigation, and payload behavior into one synchronized system. It is the component that turns a collection of motors, sensors, and pumps into an aircraft that can fly a planned route over a field by itself.
The module handles real-time flight coordination, sensor integration, GPS and RTK signal handling, and data relay between the aircraft body systems and the remote controller. It arrives with pre-installed firmware and integrated communication ports, which is what allows it to be installed as a defined replacement job rather than an open-ended electronics project. Everything the aircraft knows about where it is, what is around it, how it is oriented, and what it has been told to do converges here — which is also why a fault in this one module can surface as a fault in almost any other.
The Aerial Electronics System Module coordinates:
Commercial agricultural drones work this module hard every operating day, including through:
Throughout that duty, avionics hardware sits in one of the least forgiving environments on the aircraft and is routinely exposed to:
Over time that duty stresses solder joints, connectors, and processing hardware — and because this module is the hub every other system reports through, its degradation tends to be read as somebody else's fault first. Operators can spend real money replacing sensors, cables, and peripheral boards that were only ever the messenger.
A sound Aerial Electronics System Module helps maintain:
For operators whose entire schedule sits on one or two airframes, avionics availability is not a convenience — it is the recovery plan.
The Aerial Electronics System / Avionics Module is designed to serve as the central flight control and processing hub of the aircraft, coordinating navigation, sensing, propulsion, and payload into one synchronized system.
The module helps:
Nothing else on the aircraft can substitute for this board. Propulsion can be re-motored, a pump can be swapped, a nozzle can be cleaned in the truck — but there is no flying around a failed central processor. It is the one component whose absence stops every mission at once.
A sound module keeps navigation, sensing, and propulsion talking to each other in the same language, flight after flight, through a full season of commercial duty.
A failing avionics module may contribute to:
Replacing a failed module restores the coordinated, autonomous operation the aircraft was engineered around.
Replacement may be recommended when operators observe:
Common causes of avionics failure include vibration fatiguing solder joints and connector seats across seasons of flight, heat cycling stressing processing hardware every time the aircraft powers up and shuts down, electrical transients arriving at battery connection and disconnection, moisture and chemical mist working past seals in field conditions, corrosion attacking ports and traces on machines that live outdoors, and impact damage from hard landings or crop-canopy strikes. Some of these arrive suddenly and some accumulate quietly over a season. The pattern worth learning is the second kind: an aircraft that has become slightly less predictable, that logs faults which never quite reproduce, and that has already had two or three peripherals replaced without the behavior fully going away.
For commercial operators, a module on the shelf is usually cheaper than a week of the aircraft sitting while the fault is narrowed down by elimination.

Especially valuable during:
When the aircraft stops thinking, having the module on the shelf is what keeps the schedule intact.
An agricultural drone is a set of good components and one conversation between them. Motors, pumps, nozzles, radar, GNSS, and the remote controller are all capable hardware, but none of them decides anything. The aerial electronics module is where the decision happens — and when that conversation breaks down, every participant starts looking guilty. This is why avionics faults are the most expensive kind to chase: the symptom appears in the sensor, the arm, or the payload, so that is where the money goes first.
Replacing the module ends the guessing. A fresh mainboard with pre-installed firmware gives the airframe a known-good processing baseline, which does two things at once. It restores the aircraft, and it turns any surviving fault into a bounded problem — because whatever is still wrong after a module replacement is definitively not the mainboard. On a machine that has already eaten a week of diagnosis, that certainty is worth as much as the repair. Shops that keep avionics on the shelf are not being lavish with inventory; they are refusing to let a single board hold a season hostage.
The Aerial Electronics System Module helps maintain:
Without avionics on hand, operators risk:
For practical, hardworking operators, the value is simple:
Protect the module. Protect the aircraft. Protect the mission. Protect the season.
Professional DJI Agras operators understand that autonomy is only as reliable as the board that produces it. Keeping an aerial electronics module in the repair inventory means a grounded airframe becomes a bench job instead of a lost month — and that difference is what separates a good season from a frustrating one.

What is the DJI Agras Aerial Electronics System / Avionics Module? It is the main flight control board of the aircraft — the central processor that handles real-time flight coordination, sensor integration, GPS and RTK signal handling, and data relay between the aircraft's body systems and the remote controller. It is what allows the drone to fly a planned route autonomously rather than simply respond to stick inputs. Ares Acres LLC, a U.S.-based authorized DJI Agras reseller, stocks it brand new, one module per order, with pre-installed firmware and integrated communication ports.
What does it fit? The module is listed for the DJI Agras T50, and the supplier also lists it for the DJI Agras T40 and DJI Agras T25 (supplier-listed). Because avionics modules are revision-sensitive, match the part against your aircraft's parts diagram or the label on the module currently installed before ordering, and confirm the model your airframe is built to.
How do I tell an avionics module failure from a sensor, ESC, or GNSS failure? Look at how many systems are complaining and whether the complaint travels. A genuine peripheral failure is usually singular and consistent: one sensor, one arm, one motor, the same fault every time, reproducible on the bench, and it moves with the component if you swap it to another position or another airframe. An avionics module problem behaves the opposite way — unrelated systems report faults on the same aircraft, errors appear and clear without a clean pattern, RTK or positioning drops out under conditions that were fine last week, and missions fail to start for reasons that change. Two signs carry the most weight. First, faults that stay with the airframe after the reported peripheral has already been replaced, including replacement parts that fault the same way the originals did. Second, physical evidence at the module itself: moisture intrusion, corrosion on ports and connectors, heat discoloration, or impact damage after a hard landing. That evidence is close to decisive, because a downstream sensor cannot corrode the board upstream of it. Getting this call right is where the money is — an operator chasing scattered errors one peripheral at a time can replace several assemblies and still be flying the cause.
Why replace the module instead of continuing to replace the parts that report the faults? Because on a hub component the reported fault and the failed part are frequently not the same thing. Every sensor, ESC, and controller link on the aircraft reports through this board, so a degraded board can generate believable evidence against hardware that is perfectly healthy. Replacing peripherals in sequence is the slowest and most expensive way to arrive at the mainboard, and it usually happens during the exact weeks the aircraft needs to be flying.
Is the module ready to use out of the box? It ships brand new with pre-installed firmware, integrated communication ports, a basic setup guide for replacement and calibration, and electrostatic-safe packaging. It is a direct-fit replacement rather than a bare board to be sourced and matched afterward. Treat the installation as flight-critical bench work: follow the setup and calibration guidance, verify sensor and positioning behavior on the ground, and fly a short verification pass before the aircraft returns to paid work.
Why does a single board failure affect navigation, sensing, and payload all at once? Because all three depend on the same processing hub. Positioning data, inertial and radar input, controller commands, and payload timing converge on this module and leave it as coordinated instruction. When the hub degrades, everything downstream of it inherits the problem, which is why avionics symptoms so rarely look like avionics symptoms at first.
What are the signs an aerial electronics module needs replacing? The aircraft refuses to arm, flight control or attitude errors repeat, GPS or RTK fix will not hold, sensor errors appear across unrelated systems, obstacle avoidance behaves inconsistently, missions will not upload or complete, communication with the remote controller drops, or faults persist after peripherals have been replaced. Visible evidence counts too — moisture intrusion, corrosion on the board or connectors, heat discoloration, or physical damage after a hard landing.
What causes these modules to fail? Vibration fatiguing solder joints and connector seats across seasons of flight, heat cycling stressing processing hardware through every power-up and shutdown, electrical transients at battery connection and disconnection, moisture and chemical mist reaching the electronics in field conditions, corrosion on ports and traces, and impact damage from hard landings or canopy strikes. None of that is unusual duty for an agricultural aircraft — it is simply what a full season of commercial spraying does to flight electronics.
