DJI Agras T100 OEM Core Board (Main Control Board) — OEM flight control system, central processing unit, and communication & power management hub for the DJI Agras T100 and DJI T70P.
🇺🇸 U.S.A. FIRST
When the core board goes down, the whole aircraft goes down with it — and a grounded sprayer during a spray window costs an American operator far more than the board does. This is the brain of the machine. Get the right OEM unit, get it in, and get back over the crop while the weather still lets you fly.

🔧 Component Overview
The DJI Agras T100 / T70P Original Core Board is the central processing unit of the aircraft, responsible for managing all flight operations, communication systems, and internal component coordination.
This OEM DJI-spec core board serves as the primary control hub, integrating flight control algorithms, sensor data processing, and system-wide communication between ESCs, radar, RTK modules, and power systems.
The core board is critical to maintaining stable flight performance, accurate navigation, and real-time system response. Any failure or degradation in this component can lead to major operational issues, including loss of communication, flight instability, or system shutdown.
This is a mission-critical electronic component, essential for full aircraft functionality.
Working environments this board has to survive:
- Constant airframe vibration from eight-rotor propulsion loads
- Heat soak inside a sealed electronics compartment on hot spray days
- Humidity, condensation, and washdown moisture after chemical runs
- Agrochemical vapor and fine field dust working past seals
- Electrical stress from high-current battery cycling and ESC switching
- Transport shock from loading, hauling, and field-to-field moves
⚙️ Functional Purpose
The core board is designed to:
- Manage and execute flight control operations
- Process sensor data (IMU, radar, RTK, GPS)
- Coordinate communication between ESCs and motors
- Control power distribution and system logic
- Enable communication with the remote controller
- Maintain system stability and real-time responsiveness
⚠️ Common Replacement Indicators
- Drone fails to power on or initialize
- Persistent system or communication errors
- Unstable or inconsistent flight behavior
- Failure to connect to remote controller
- Sensor or module communication faults
- Damage from electrical failure, moisture, or impact
- Errors that follow the airframe no matter which battery, arm, or module is swapped
Diagnostic note: core board failures love to disguise themselves as module failures. If you have already replaced a sensor, an ESC, or a cable and the same fault code keeps coming back — or if multiple unrelated subsystems start throwing errors at once — the common denominator is the board they all report through, not the modules themselves.
What kills core boards in the field:
- Moisture ingress after a washdown with a compartment seal left open
- Vibration fatigue on solder joints and connector seats over long seasons
- Thermal cycling from full-load spray runs into cold overnight storage
- Voltage spikes and hot-swap abuse on the high-current power path
- Impact damage from a hard landing or a transport drop

🚜 Necessary For
This component is essential inventory for:
- Operators restoring full aircraft functionality
- Repair teams diagnosing flight control or communication failures
- Technicians performing full system rebuilds or refurbishments
- Farms and contractors requiring reliable, uninterrupted flight operations
- Fleet operators who cannot afford an aircraft sitting dead through a spray window
💡 Why This Part Matters
The core board is the brain of the aircraft—controlling every critical function from flight stability to system communication.
A compromised core board can result in complete system failure or unsafe operating conditions.
Replacing the core board:
- Restores full flight control and system functionality
- Re-establishes communication between all onboard components
- Improves reliability and operational safety
- Ensures consistent performance under demanding agricultural workloads
Experienced operators prioritize core system integrity to protect high-value aircraft and maintain operational uptime.
After installation:
- Seat every connector fully and confirm the harness routing matches the original layout
- Verify the electronics compartment seal is clean and closed before the first power-up
- Power up on the ground and confirm the controller links and all modules report in
- Run a sensor and compass calibration, then check for lingering fault codes
- Fly a short low-altitude hover and a clean test pass before loading a full tank
Restore the brain. Link the systems. Steady the flight. Finish the field.
