In-Depth Internal Component Analysis / Teardown
Precision Power & Signal Management Board
The internal photograph reveals a meticulously engineered PCB with a black ENIG finish, characteristic of DJI’s high standards. The layout is modular, with distinct zones for power management and signal processing, separated by gold traces for RF isolation. While most major ICs are unpopulated in this view, the presence of smaller SMD components, crystals, and extensive test points suggests this board is dedicated to local power regulation, clock distribution, and interface logic. The density of vias and controlled impedance routing indicate a multi-layer design optimized for high-speed signals and robust EMI/RFI suppression. The large gold-bordered area is clearly intended for an EMI shield, underscoring the importance of noise control in drone applications. This board likely serves as a central hub for managing power distribution and low-level communications between sensors, controllers, and RF modules, playing a vital role in the drone’s reliable operation.
High-Performance RF & Antenna Interface Board
This board exemplifies DJI’s expertise in RF design and system integration. The most prominent features are two intricately designed PCB trace antennas, likely tuned for the 2.4 GHz and 5.8 GHz bands, enabling robust wireless communications for telemetry, video, and control. The layout is highly organized, with analog/RF and digital sections clearly separated and extensive ground pours for EMI suppression. Multiple high-density connectors along the board’s edge facilitate seamless integration with other drone subsystems. The absence of metal shielding in this stage suggests further assembly steps, but the unpopulated shield area and via stitching confirm careful RF design. Local power regulation components support sensitive analog circuits, while onboard oscillators ensure precise timing for wireless operations. This board is a cornerstone of the Agras T25’s communication subsystem, delivering reliable, long-range connectivity essential for professional agricultural UAV missions.
Circular Sensor or Control Module
The circular PCB, densely populated with ICs and passives, is indicative of a highly integrated sensor or control module. The presence of larger QFN/BGA ICs suggests embedded processing or sensor fusion capabilities, while multiple crystals provide precise clocking for time-critical applications. The central hole and mounting provisions point to a stacked or gimbal-mounted assembly—possibly for the drone’s omnidirectional radar, gimbal stabilization, or environmental sensing. Local power regulation is achieved through visible inductors and capacitors, ensuring clean power delivery to sensitive circuits. The dense via placement and ground pours reinforce EMI resilience. Although no antennas are visible, the board’s complexity and compactness highlight the Agras T25’s modular approach, allowing for easy upgrades or repairs in the field.
Power Distribution & Motor Driver Board
This PCB stands out for its robust thermal management and power handling capabilities. Large ICs, some covered with thermal interface material, are likely high-power MOSFETs or H-bridge drivers responsible for controlling the drone’s brushless motors. The layout features clear separation between power and logic domains, minimizing EMI and ensuring operational stability. Gold-plated edge contacts and FPC connectors enable reliable interconnection with other subsystems. Multiple large inductors and capacitors support high-current regulation, crucial for consistent motor performance during demanding spray missions. The presence of well-labeled test points and blue thermal pads indicates a design focused on serviceability and long-term reliability. This board is central to the Agras T25’s propulsion and power distribution, directly impacting flight efficiency and safety.
