Introduction

Overview
The SM35B02 is a highly integrated AIoT module with built-in low power dual-band Wi-Fi 802.11 a/b/g/n and Bluetooth specification 5.1. The high- resolution 1080P camera interface can transmit images immediately with low latency via high-performance Wi-Fi. This module includes a powerful NPU AI computing engine to accelerate AI model processing and can be widely used in various IoT applications that need image processing, (like image recognition, and face recognition…), suitable for smart homes, industrial smart control, smart retail, health care or automotive electronics markets.
With the small size design of this module, it can easily fit into the product space. A variety of pre-trained AI models will be supported directly in the module so it can be quickly applied to each kind of application.

FCC

Federal Communications Commission (FCC) Statement
You are cautioned that changes or modifications not expressly approved by the part responsible for compliance
could void the user’s authority to operate the equipment.

This equipment has been tested and found to comply with the limits for a Class B digital device, under part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used by the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

1. this device may not cause harmful interference, and
2. this device must accept any interference received, including interference that may cause undesired operation of the device.

FCC RF Radiation Exposure Statement

1. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
2. This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body.

This equipment should be installed.
Note: The end product shall have the words “Contains Transmitter Module FCC ID: 2AOAOSM35B02”

OEM statement
The Original Equipment Manufacturer (OEM) must ensure that the OEM modular transmitter must be labeled with its own FCC ID number. This includes a visible label on the outside of the final product enclosure that displays the contents shown below. If
the FCC ID is not visible when the equipment is installed inside another device, then the outside of the device into which the equipment is installed must also display a label referring to the enclosed equipment. The end product with this module may be subject to FCC part 15B unintentional emission test requirements and be properly authorized while installation to host(s), and platform, and the integrator is obligated to have its manual or instruction with the related compliance warning to end users.

This device is intended for OEM integrators only
The end product with this module may be subject to re-evaluating RF exposure as per 47CFR § 2.1091, and §2.1093 if the antenna or usage, including co- located usage of other transmitters, of the subsequent installation is changed.

This radio transmitter has been approved by FCC/Innovation, Science and Economic Development Canada to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that Have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device. PCB Trace Antennas: 2.4G:3.12dBi / 5G:4.54dBi
