In-Depth Internal Component Analysis / Teardown

Rotary Encoder and User Input Sub-Board

A compact sub-board houses a prominent blue rectangular component marked ‘1038 703C’, which functions as a potentiometer or rotary encoder—essential for precise analog user input such as dial or knob control. The board’s clean, black FR4 construction, flat flexible cable interface, and minimal component count suggest a low-power, high-reliability design focused on user interface functionality. No RF, power, or processing components are present, reinforcing its role as a modular input assembly. The robust mounting and straightforward layout facilitate easy replacement and long-term durability, aligning with the professional build standards expected in the Cendence Remote Controller.

Simple Rotary Encoder Subassembly

This subassembly consists of a green, single-sided PCB supporting a mechanical rotary encoder or potentiometer, with minimal trace routing and a bundle of connecting wires. Its straightforward design—lacking complex ICs or RF components—reflects its role as a dedicated user interface element, likely for adjusting gimbal or camera parameters. Through-hole mounting ensures mechanical stability, while the modular wiring enables straightforward integration and maintenance. The design prioritizes reliability and ease of service, making it a vital yet uncomplicated part of the controller’s overall user input system.

Modular Switch Assemblies

A collection of small, single-sided PCBs populated with tactile switches and lever actuators forms the backbone of the Cendence’s customizable button interface. The green FR4 boards, connected via flat ribbon cables, are optimized for high-cycle reliability and ease of replacement. Their wide traces and basic grounding reflect low-speed, low-frequency operation, suitable for direct user input rather than signal processing or RF communication. The modular design ensures that individual switch assemblies can be serviced independently, supporting the controller’s field-repairable architecture.

Indicator and Toggle Switch Modules

This set of internal modules features small black PCBs equipped with tactile pushbuttons, toggle switches, and likely indicator LEDs. Connected via flat flexible cables and labeled for specific functions (e.g., ‘FOCUS-R’, ‘HL-ASS’), these subassemblies handle critical user interface roles such as mode selection and input feedback. The minimal component density and absence of complex ICs or RF elements highlight their dedicated function as reliable, modular user input and status indicator units, further contributing to the controller’s customizable and serviceable design ethos.

Shielded RF/Digital Module

Dominating the internal architecture is a high-density, multi-layer PCB module enveloped in extensive EMI/RFI shielding. The presence of a coaxial RF connector, gold-finger edge connector, and robust grounding points signifies its central role in wireless communication—likely integrating RF transceivers, digital processing, and power management ICs beneath the shields. The modular, serviceable construction allows for future upgrades or repairs, while the heavy shielding and careful partitioning ensure optimal RF performance and minimal interference—critical for long-range, high-reliability drone control.

Integrated Antenna PCB and Shielding

A white PCB featuring large planar copper traces acts as the integrated antenna system, optimized for operation in the 2.4 GHz and/or 5.8 GHz ISM bands. The substantial metal plate adjacent to the board serves as both EMI/RFI shielding and mechanical reinforcement. The design leverages PCB antennas for compactness and reliability, with careful attention to trace geometry and grounding to ensure consistent, high-quality wireless performance—underscoring DJI’s expertise in RF engineering for mission-critical applications.

Main Controller PCB and Housing

The main PCB, housed within the controller’s robust chassis, features multiple high-integration ICs (likely including the main SoC, RF transceivers, and memory), dense via structures, and a modular layout with FPC/FFC connectors for joysticks, buttons, and displays. Extensive power management circuits, test points, and crystal oscillators are evident, supporting the controller’s complex RF, video, and telemetry functions. The design also accommodates coaxial connectors for external or internal antennas, with a focus on EMI/RFI control and mechanical stability. The overall construction reflects DJI’s commitment to high build quality, modularity, and serviceability in professional equipment.

Antenna Subsystem and RF Module

A pair of large, white PCB antennas and a compact black PCB module comprise the core of the Cendence’s RF front-end. The antennas, likely of IFA or similar planar design, are engineered for efficient 2.4 GHz/5.8 GHz operation, while the small module hosts RF signal processing or antenna switching ICs. Clean trace routing, modular construction, and attention to ground plane integrity ensure robust wireless communication and ease of assembly or replacement—hallmarks of a well-designed RF subsystem in a high-end controller.
