In-Depth Internal Component Analysis / Teardown

Main Flight Controller PCB with Rockchip RK3288 SoC

At the heart of the AGRAS MG-1S lies a meticulously engineered main PCB, anchored by the Rockchip RK3288—a powerful quad-core ARM Cortex-A17 system-on-chip. This processor delivers substantial computational capability, enabling real-time flight control, image processing, and advanced automation tasks. Flanking the SoC are large BGA-packaged DRAM and flash memory modules, providing the high-speed volatile and persistent storage necessary for mission data, maps, and system firmware. The PCB’s black ENIG finish and dense via placement point to a multi-layer (likely 6+ layers) design, optimized for signal integrity and EMI resilience. Differential pair routing supports high-speed interfaces, while robust ground pours and stitching vias minimize electromagnetic interference. A prominent metal shield protects sensitive RF and digital circuits, and a white U.FL connector at the board’s edge allows for modular antenna attachment. The overall build quality reflects DJI’s commitment to reliability and serviceability, supporting the demanding operational environment of agricultural drones.
