Declaration of Differences 2025/12/15 We, GWELL TECHNOLOGY CO., LTD., hereby declare the differences among the following Semtech LoRa transceiver chips: SX1262, and LLCC68. Parameter SX1262 LLCC68 Link Budget 170 dB 151 dB Max Tx Power +22 dBm +22 dBm Sensitivity -148 dBm -129 dBm Modulations LoRa, LR-FHSS, GFSK LoRa, GFSK Frequency Range 150 MHz ~ 960 MHz 150 MHz ~ 960 MHz Key Clarification 1. Main Chip: The module variants use different LoRa transceiver ICs (SX1262 vs LLCC68). 2. Functional Differences: Receiver sensitivity/link budget and modulation support differ with IC selection (see table above). 3. Transmit/Regulatory: Same frequency range and maximum transmit power are configured; RX differences do not affect transmitter emissions. Parameter Summary • Main Chip: SX1262 or LLCC68 (different) • TX: 150 MHz - 960 MHz, up to +22 dBm (configured the same) • RX / Features: Sensitivity, link budget, and modulation support differ (see table above) Statement The variants use different main transceiver ICs (SX1262 vs LLCC68). For compliance evaluation, transmitter operation (frequency range and maximum transmit power) is configured the same; therefore, transmitter-related regulatory characteristics are considered equivalent for both variants.

QA-FR-175-B Modular Approval Letter 2025/08/26 FEDERAL COMMUNICATIONS COMMISSIONS Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Subject: Modular Approval Letter The Device, FCC ID: 2AEMSGWLORA-A0, is seeking FCC authorization as a modular transmitter. The EUT meets the requirement for modular approval as detailed in FCC Public Notice DA 00-1407. Compliance to each of the requirements is described below: Item § 15.212 Requirement Y/N Comments (i) The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements. Y The module RF section is shielded. Please see external photos. (ii) The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over-modulation. Y The module chipset integrates buffered modulation/data inputs. (iii) The modular transmitter must have its own power supply regulation. Y On-board regulator ensures stable operation. (iv) The modular transmitter must comply with the antenna and transmission system requirements of §§15.203, 15.204(b) and 15.204(c). 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 (b) of this section. Y The module is designed with an onboard PCB antenna and an external Dipole antenna via a unique connector. The antennas used are limited to those specified in the filing. (v) The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with part 15 requirements. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in § 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be Y Compliance test was conducted in stand-alone mode per §15.207. QA-FR-175-B marketed with the module (see § 15.27(a)). The length of these lines shall be the 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 and commercially available (see § 15.31(i)). (vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. Y The module has a permanent label with FCC ID. See label exhibit. (vii) The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. Y User manual contains integration instructions and applicable conditions. (viii) Radio frequency devices operating under the provisions of this part are subject to the radio frequency radiation exposure requirements specified in §§ 1.1307(b), 1.1310, 2.1091, and 2.1093 of this chapter. Y RF exposure compliance addressed in RF exposure report. Sincerely Yours, James Liu Gwell Technology Co., Ltd.
