I O I I/O 1. AC_TRIAC_DETECT is used to detect if a device is powered through a triac dimmer and to determine the dimmer settings. The circuit that feeds this signal should give a scaled DC voltage representation of the average AC voltage integrated over approximately 200ms. If the triac is set to chop the AC waveform 50%, the AC_TRIAC_DETECT signal should be at 50% of VCC.If the triac dimmer is turned up completely, the AC waveform will be minimally chopped and the AC_TRIAC_DETECT signal should be at 100% of VCC. 10 11 12 13 14 Note:

Type of Confidentiality Requested Short Term Short Term Short Term Short Term Short Term Short Term Short Term Short Term Permanent Permanent Permanent Permanent Permanent Permanent Exhibit Block Diagrams External Photos Internal Photos Operation Description/Theory of Operation Part List/Tune-Up Procedure Schematics Test Setup Photos Users Manual LEEDARSON LIGHTING CO., LTD. has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality:

The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality:

The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of 180 days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify TUV Rheinland in the event information regarding the product or the product is made available to the public. TUV Rheinland will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-

Date: 2020-07-30 FCC ID:2AB2Q-MLA02302 IC: 10256A-MLA02302 Type of Module: Single Modular Transmitter No. 1 Requirements 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. Device Conditions The module has its own RF shielding. Refer to the external photos. Comply (Y/N) Y 2 3 4 5 6 7 8 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. The EUT has buffered modulation/data inputs. Its integrated on the chipset IC U1 /

ESP32-U4WDH. Refer to the schematics diagram. The modular transmitter must have its own power supply regulation. 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. The module has its own power supply regulation. The antenna is permanently on the PCB and antenna gain is

-0.2dBi. 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. The modular transmitter was tested in a stand-alone configuration via a laptop PC USB interface. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. FCC ID is permanently on the PCB. Refer to the Label Location and Label. The User Manual instruction that the OEM how to use the label. Y Y Y Y Y Y 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. The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. Refer to the test report.
