In-Depth Internal Component Analysis / Teardown
Main PCB: Core Control and Communication Module
A close examination of the main PCB reveals a densely populated, multi-layer board—likely with four or more layers—showcasing DJI’s commitment to high-quality, reliable electronics. Several medium-sized integrated circuits are visible, which likely serve as microcontrollers, RF transceivers, or power management units, forming the heart of the WM230’s control and communication systems. Differential pairs and impedance-controlled traces suggest high-speed data or RF signal routing, while abundant ground vias and sophisticated power regulation components (large capacitors and inductors) indicate careful attention to signal integrity and EMI control. The modular approach, with multiple FPC/FFC and power connectors, points to a design optimized for both manufacturability and repair. The overall build demonstrates robust engineering practices necessary for a high-performance drone or remote controller.
Precision Submodule: Power or Sensor Interface Board
This submodule displays a compact, green multi-layer PCB populated with a prominent ‘MP66’ (likely power management or sensor interface IC) and a scattering of passive components. Clean soldering and mounting holes suggest it is designed for precision placement and mechanical stability within the drone’s assembly. While the cropped view limits visibility of connectors or antennas, the density and layout reflect a module optimized for reliability and noise reduction, possibly handling sensor inputs or localized power regulation. The absence of large capacitors or inductors hints that this is not the main power supply but could be essential for interfacing sensitive sensors or subsystems in the WM230.
Ceramic Patch Antenna Module: GNSS Reception
The internal antenna module is dominated by a ceramic patch antenna, expertly mounted on a black ENIG-finished PCB with multiple gold-plated grounding and mounting holes. This design is indicative of a GNSS (GPS/GLONASS/BeiDou/Galileo) reception module, critical for drone navigation and positioning. The central mounting screw likely serves both mechanical and electrical purposes, ensuring optimal grounding and RF performance. The overall construction supports high-sensitivity signal acquisition, with the modular setup allowing for straightforward replacement or upgrades. The precision and robust build quality here underscore DJI’s focus on reliable navigation in diverse flight environments.
GNSS Navigation PCB: u-blox M8030 Integration
A highlight of the WM230’s internal engineering is the integration of a u-blox M8030-KT chip, a high-performance multi-constellation GNSS receiver, onto a densely populated black PCB. The chip is surrounded by a soldered metal RF shield, essential for minimizing interference and ensuring accuracy in positioning data. The PCB features a carefully routed trace antenna, controlled impedance lines, and a multitude of test points, reflecting a meticulous RF design. Supporting components include crystals for timing, small inductors and capacitors for power filtering, and additional ICs for power management.
