2BWYT-QCG18F30Data transmission module

Rainbow Dynamics Inc 8314 Sherwick Ct, Jessup, MD 20794, United States QCG18F30 User Manual General QCG18F30 is a highly integrated, cost-effective, high-power 16-channel full-duplex data transmission module. It features a built-in high-speed micro-controller, high-performance RF transceiver chip, and RF power amplifier. The module provides a standard serial port for communication, enabling easy and quick parameter settings and control of the transmit/receive functions. Users can achieve data transmission simply by connecting the module to the serial port. Its ultra-compact size allows for easy and fast integration into various handheld devices, enhancing the overall performance of terminal products, making this module widely applicable. QCG18F30 is a 16-way full-duplex wireless data communication module that can achieve up to 16 transmitters transmitting simultaneously without interfering with each other. It is designed for scenarios where multiple transmitters operate concurrently in complex environments, minimizing the likelihood of re-transmissions and significantly reducing interference and the chances of being interfered with. The combination of LoRa modulation with 1W output power, along with its low-power design for receiving and sleep modes, makes it ideal for long-distance wireless IoT applications. 2 Parameters List Power supply: 3.3V DC Frequency band: 902.125-917.125MHz Channel Number: 16 Channel Separation: 1MHz Modulation: LoRa Max. peak power: [email protected] Antenna: Permanently attached folding rod antenna, 2.15dBi Module Dimensions: 3 Reset Timing Diagram Power-on Reset Timing Diagram Operating State Reset Timing Diagram Communication protocol The module provides a user-friendly interface (standard serial port), allowing users to send commands via the serial port to control the module and read its parameters. 4 Pin Definition Pin NO.

Rainbow Dynamics Inc 070920-02b Request for Modular/Limited Modular Approval Date: July 31, 2026 Subject: Manufacturer’s Declaration for ☒ - Modular Approval ☐ - Split Modular Approval ☐ - Limited Modular Approval ☐ - Limited Split Modular Approval Confidentiality Request for: ______2BWYT-QCG18F30______ 8 Basic Requirements – FCC Part 15.212(a)(1) For Items Marked “NO(*)”, the Limited Module Description Must be Filled Out on the Following Pages Modular Approval Requirement Requirement Met 1. The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with FCC limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation. The physical crystal and tuning capacitors may be located external to the shielded radio elements. 15.212(a)(1)(i) ☒ - YES ☐ - NO(*) Details: The module contains a metal shield which covers all RF components and circuitry. The shield is located on the top of the board next to antenna connector. 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with FCC requirements under conditions of excessive data rates or over-modulation. 15.212(a)(1)(ii) ☒ - YES ☐ - NO(*) Details: Data to the modulation circuit is buffered as described in the operational description provided with the application. 3. The modular transmitter must have its own power supply regulation on the module. This is intended to ensure that the module will comply with FCC requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. 15.212(a)(1)(iii) ☒ - YES ☐ - NO(*) Details: The module contains own power supply regulation. Please refer to schematic filed with this application. 4. The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b), 15.204(c), 15.212(a), and 2.929(b). The antenna must either be permanently attached or employ a ‘‘unique’’ antenna coupler (at all connections between the module and the antenna, including the cable). The ‘‘professional installation’’ provision of § 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph 15.212(b). 15.212(a)(1)(iv) ☒ - YES ☐ - NO(*) Details: The module uses permanently attached straight rod antenna. Please refer to the internal photos for details. 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see Section 15.31(i)). 15.212(a)(1)(v) ☒ - YES ☐ - NO(*) Details: The module was tested stand-alone as shown in test setup photographs filed with this application. Rainbow Dynamics Inc 070920-02b Modular Approval Requirement Requirement Met 6. The modular transmitter must be labeled with its own FCC ID number, or use an electron display (see KDB Publication 784748). If using a permanently affixed label with its own FCC ID number, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. If the modular transmitter uses an electronic display of the FCC identification number, the information must be readily accessible and visible on the modular transmitter or on the device in which it is installed. If the module is installed inside another device, then the outside of the device into which the module is installed must display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains FCC certified transmitter module(s).” Any similar wording that expresses the same meaning may be used. The user manual must include instructions on how to access the electronic display. A copy of these instructions must be included in the application for equipment authorization. 15.212(a)(1)(vi) ☒ - YES ☐ - NO(*) Details: There is a label on the module as shown in the labeling exhibit filed with this application. Host specific labeling instructions are shown in the installation manual .filed with this application. 7. The modular transmitter must comply with all specific rule or operating requirements applicable to the transmitter, including all the conditions provided in the integration instructions by th…
