Based on the provided identifier **"2AMLS3"**, this corresponds to an **FCC ID** registered by **SZ DJI TECHNOLOGY CO., LTD**. This specific FCC ID is associated with the **DJI RC-N1 Remote Controller** (specifically the hardware internal to the 2.4GHz/5.8GHz transmission systems used for drones like the Mavic 3, Air 2S, and Mini 2). --- ## 1. Device Overview The 2AMLS3 refers to the radio communication module within the **RC-N1 Remote Controller**. It serves as the primary ground station link between the pilot and the Unmanned Aerial Vehicle (UAV). ### Technical Specifications | Feature | Details | | :--- | :--- | | **FCC ID** | 2AMLS3 | | **Frequency Range** | 2.400 - 2.4835 GHz / 5.725 - 5.850 GHz | | **Max Output Power** | Approx. 26 dBm (2.4G) / 26 dBm (5.8G) | | **Modulation Type** | OFDM (Orthogonal Frequency Division Multiplexing) | | **Transmission System** | OcuSync 2.0 / O3 (depending on firmware) | --- ## 2. Key Electronic Components The internal PCB (Printed Circuit Board) of the 2AMLS3 device consists of several critical sub-systems: ### A. The RF Front-End (Radio Frequency) * **Transceivers:** Highly integrated chips designed to handle the OcuSync protocol, switching between 2.4GHz and 5.8GHz to avoid interference. * **Power Amplifiers (PA):** Boosts the outgoing signal to ensure long-range control (up to 10-12km in ideal conditions). * **Low Noise Amplifiers (LNA):** Sensitive components that amplify the weak signals returning from the drone (telemetry and live video). ### B. Processing Unit * **Main SoC:** A DJI-proprietary or semi-custom ARM-based processor that handles the video decoding, USB communication with the smartphone, and encryption of the control link. * **Flash Memory & RAM:** Used for storing firmware and buffering the high-definition video stream before it is sent to the mobile device. ### C. Power Management * **Li-ion Battery Cell:** Typically a 1S2P or 2S configuration (approx. 5200 mAh). * **PMIC (Power Management IC):** Manages the charging via USB-C and distributes regulated voltages (3.3V, 1.8V, 1.2V) to the RF chips and processor. --- ## 3. Connectivity Interfaces The electronics are designed to bridge the drone's wireless signal to a physical mobile device: * **USB-C Port:** Used for both charging the internal battery and high-speed data transfer to the smartphone. * **Antenna System:** Dual-polarized antennas integrated into the top housing (the "cradle" that holds the phone). --- ## 4. Compliance Information The **2AMLS3** certification ensures the device meets FCC Part 15 subpart C/E requirements. This means the electronics are tested to: 1. Not cause harmful interference. 2. Accept any interference received. 3. Operate within the legal SAR (Specific Absorption Rate) limits for human exposure to RF.
