Operating Frequencies
According to the FCC filing for FCC ID SS3-PL512M21611, there is no detailed frequency data available or parsed for this device.
For most storage modules like the CINESSD, this is expected. These devices do not contain intentional RF transmitters or receivers (such as Wi-Fi or Bluetooth radios). Instead, their primary function is high-speed data storage and transfer via wired interfaces (PCIe/NVMe or SATA).
However, compliance with FCC regulations ensures that any unintentional emissions—such as electromagnetic interference generated by high-speed digital circuits—remain within safe, regulated limits. This is crucial for preventing interference with other onboard wireless systems, especially in drone and professional video environments.
Technology Deep Dive
The DJI CINESSD, under model CINESSD and FCC ID SS3-PL512M21611, is fundamentally a high-performance solid-state storage module. It does not incorporate intentional wireless technologies such as Wi-Fi, Bluetooth, or cellular radios. Instead, its core technology revolves around advanced NAND flash memory and a high-speed SSD controller, interfaced via the M.2 edge connector for PCIe/NVMe or SATA connectivity.
The absence of specific operating frequencies highlights the device’s nature as a passive electronic component with respect to RF communications. However, the internal high-speed digital signals—especially those routed over PCIe/NVMe—necessitate careful PCB layout, grounding, and shielding to minimize electromagnetic emissions. This is particularly important in drone applications, where the proximity of storage modules to sensitive RF equipment (GPS, telemetry, video transmission) demands strict EMC (electromagnetic compatibility) standards.
From a performance standpoint, the use of multi-layer PCBs, BGA-packaged NAND, and a dedicated controller ensures low latency and high throughput. This architecture supports the sustained write speeds required for high-resolution, high-frame-rate video capture—an essential capability for professionals relying on DJI’s aerial platforms. The device’s power management circuitry further aids in optimizing efficiency, minimizing heat generation, and ensuring reliable operation during extended shoots.
Test report summaries, while not available in detail for this filing, would typically confirm that the CINESSD meets all FCC Part 15 requirements for unintentional radiators, validating its use in environments where low EMI is critical.
In-Depth Internal Component Analysis / Teardown
High-Density NAND and Controller Architecture
Upon removal of the EMI shield, the heart of the CINESSD’s design is revealed: a densely populated M.2 2280 PCB packed with high-performance components. Dominating the board are several large BGA-packaged ICs, which serve as the primary NAND flash memory banks—likely sourced from industry leaders to ensure data reliability and speed. Centrally positioned, a prominent SSD controller orchestrates all memory operations, balancing wear leveling, error correction, and high-speed host communication. Surrounding these main elements are smaller ICs, potentially DRAM for caching and power management units, all supported by a robust array of surface-mount passives. The PCB layout showcases tightly coupled differential pairs for PCIe/NVMe data integrity, extensive copper pours for grounding, and high-precision SMT assembly, underscoring the module’s professional-grade build quality and its optimization for demanding video capture environments.
Precision SSD Layout and High-Speed Signal Routing
Examining the opposite side of the module, the design philosophy remains clear: maximize performance within a compact footprint. Three large BGA NAND flash chips are aligned on the left, while the right side features the main controller, a testament to balanced signal routing and thermal management. The green multi-layer PCB is densely populated with small SMD passives and features differential pair traces, ensuring data integrity at the highest transfer rates. Power delivery is handled by a network of small inductors and capacitors strategically located near the controller. The absence of onboard antennas and additional connectors confirms the device’s singular focus on storage. Overall, the meticulous layout, clean soldering, and modular design reflect industry best practices for professional SSD modules intended for high-speed, high-reliability applications such as aerial video recording.
PCB Integrity and Signal Control
The reverse side of the CINESSD PCB offers insight into the foundational engineering supporting its high-speed operation. While devoid of major ICs, this side reveals a meticulously routed green PCB, with controlled impedance traces and extensive via stitching for optimal grounding. The M.2 2280 form factor is evident, as is the high-density edge connector that interfaces with the host system for PCIe-based data transfer. Several test points and manufacturing markings are present, facilitating quality control and diagnostics. The lack of components here is typical for double-sided SSDs, where one side is reserved for labeling, thermal pads, or mechanical stability. The overall design demonstrates DJI’s commitment to signal integrity, thermal efficiency, and robust construction, all essential for reliable performance in professional drone environments.
