11/15/2021 Attention: Application Examiner RE:

Request for Confidentiality Applicant: Curiouser Products Inc. FCC ID: 2AOSD-MCW3 To Whom It May Concern:

Permanent Confidentiality Request is hereby submitted by Curiouser Products Inc. to withhold permanently from public review certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept permanently confidential:

Schematics Detailed Block Diagrams Detailed Operational/Functional Description Rationale for request for confidentiality:

Curiouser Products Inc. has invested considerable time and materials in research and development to produce the referenced product. Disclosure of the permanently confidential portions of this application to competitors would not only give them significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished, leading edge technology developed by us. Disclosure of the short-term confidential portions of this application during the period of importation and/or distribution would reveal key aspects of proprietary technology to competitors and diminish the value of our investment in research and development. Sincerely, Bradley Augustine VP of Hardware Curiouser Products Inc. 1(1) DocuSign Envelope ID: 51713283-3843-4715-850B-93CEFE6B33F9

Curiouser Products Inc. FCC ID: 2AOSD-MCW3 Model Name Product type / Description Note MCWD10 MCWD15 MCWD20 MCWD25 MCWD30 MCWD35 Connected Weights Connected Weights Connected Weights Connected Weights Connected Weights Connected Weights To Whom It May Concern:

The listed above models are very similar with identical electrical schematics. Further details regarding the similarities and differences are below. DocuSign Envelope ID: 5E12EDE7-C144-4D48-B140-4D831C2D21C2 Similarities:

All models radio operation, schematics, and BOM are identical. All models use a printed PCB trace antenna in the form of a meandered, inverted-F antenna (MIFA) design provided by Texas Instruments and detailed in application note AN043. The Bluetooth radio IC is a Texas Instruments FRE014RHB. Differences:

MCWD35: The MCWD35 PCBA may be considered the base design. The PCB outline is rectangular and measures 53.50mm x 51.00mm. The MCWD35 supports a single AA battery power input. The antenna design directly matches the reference design. The battery and reset connections enter the PCBA through a 3 pin connector, and a 5 pin connector provides connection to the passive second side LED PCBA for lighting the opposite side logo. Each PCBA utilizes 12 LEDs. MCWD30: The MCWD30 uses exactly the same PCBA as the MCWD35. MCWD25: The MCWD25 uses exactly the same PCBA as the MCWD35. MCWD20: The MCWD20 weight uses a nearly identical PCBA to the MCWD35, but with a slightly modified outline. The dimensions of the MCWD20 are 57.13mm x 49.50mm. MCWD15: The MCWD15 PCBA is nearly identical to the board in the MCWD20, but has slightly reduced dimensions which are 44.97mm x 46.81mm. MCWD10: The MCWD10 PCBA is nearly identical to the PCBA in the MCWD15, but has slightly reduced dimensions which are 43.57mm x 43.58mm. The power input connector, CON2 is also moved to support different cable routing within the mechanical design.
