Significance:
Operating in the 2.4 GHz ISM band, the MG-1 leverages a globally accepted frequency range ideal for drone control and telemetry. The relatively high output power (906 mW) supports robust, long-range wireless links—critical for maintaining control and data integrity over large agricultural fields. Compliance with FCC Rule Part 15CMO2.124.125 ensures the device meets U.S. regulations for unlicensed wireless devices, balancing performance with minimal risk of interference to other spectrum users.

Technology Deep Dive

The AGRAS MG-1’s wireless systems are anchored in the 2.4 GHz band, a frequency commonly used for Wi-Fi, Bluetooth, and proprietary RF communications. While the equipment class is not explicitly cellular, the combination of high-output 2.4 GHz transmission and Bluetooth support provides a robust foundation for low-latency flight control, telemetry, and remote configuration.

Operating in this spectrum offers several advantages:
– Performance & Range:
The 2.4 GHz band, coupled with a 906 mW output, ensures strong signal penetration and reliable connectivity at distances up to 5 km—essential for large-scale agricultural missions.
– Interference Management:
The MG-1’s design incorporates extensive EMI/RFI shielding and advanced signal integrity practices (as observed in the teardown), reducing susceptibility to interference from other ISM band devices and ensuring stable operation in electromagnetically noisy environments.
– Power Consumption:
Efficient power management ICs and local regulation circuits (visible in the internal PCB analysis) help maintain battery life despite high transmission power.

While the FCC filings do not specify the exact Bluetooth revision, its presence suggests the MG-1 may support close-range device pairing for configuration or diagnostics. The focus on 2.4 GHz aligns with industry standards for remote control and telemetry, offering a balance between range, data throughput, and regulatory compliance.

In-Depth Internal Component Analysis / Teardown

Main Flight Control & RF Communication Modules

A close examination of the internal electronics reveals a sophisticated, multi-board assembly tailored for reliability and high performance. The left PCB showcases a dense population of integrated circuits, dominated by a large BGA package—likely the main flight controller or system-on-chip responsible for real-time drone operation. Surrounding it are memory modules and power management ICs, ensuring rapid data access and stable voltage regulation. The right PCB features gold-plated edge connectors, probably for RF signal interfacing, and is flanked by robust metallic enclosures with extensive EMI/RFI shielding. The modular, multi-layer PCB design and meticulous partitioning between processing, power, and RF domains underscore DJI’s commitment to signal integrity and electromagnetic compatibility, crucial for stable flight and wireless communication in complex environments.

Sensor Interface & Power Regulation Board

The next internal PCB is notable for its black soldermask and moderate-to-high component density. Multiple medium-sized ICs, possibly microcontrollers or power management chips, dominate the layout, with additional smaller ICs likely supporting sensor interfacing and logic functions. The board’s architecture features numerous white connectors for flat-flex cables and power delivery, test points for diagnostics, and local DC-DC converters for clean voltage supply. The layout demonstrates clear separation of analog and digital domains, with robust grounding via internal planes and stitching vias. Absence of visible RF connectors suggests this board primarily handles control logic and sensor integration, rather than direct wireless communication.

Circular Communication or Sensor Module

A circular, high-density PCB stands out for its compact, modular design and robust shielding. The upper section is anchored by a large microcontroller or SoC, likely orchestrating flight control or sensor data fusion. Gold traces on the edge hint at impedance-controlled routing, possibly supporting high-frequency or RF signals. A prominent metal shield covers the lower right, indicating a sensitive RF or high-speed digital section—possibly for telemetry, GPS, or Wi-Fi. Multiple wire harness connectors enable integration with other drone subsystems, while large capacitors and inductors point to efficient onboard power regulation. The overall design is optimized for signal integrity, EMI suppression, and modularity, all essential for UAV reliability in the field.

Circular Power Management and Signal Processing Board

Another circular PCB reveals a focused design for power management or sensor interfacing. Two large electrolytic capacitors dominate the center, ensuring ample local power filtering—vital for stable operation during high-current events like motor startup. The board features several ICs (likely operational amplifiers and microcontrollers), a compact connector for module interfacing, and multiple test points for diagnostics. Dense ground pours and stitching vias reinforce EMI resistance, compensating for the lack of metal shielding. The compact, efficient layout and presence of unpopulated pads suggest modularity and adaptability for various drone configurations.
