1. Overview
BL3353-P is an embedded Wi-Fi module designed by BroadLink, which supports
802.11 b/g/n standards and UART communication with other devices. The module
integrates radio transceiver, MAC, baseband, all Wi-Fi protocols, configurations and
network stack. It can be widely used in applications like smart home devices, remote
monitoring devices and medical care instruments.
The module integrates an ARM Cortex-M4 processor speed up to 125MHz and 256KB
SRAM with external 1MB flash.

1. In default, UART0 is used for bypass communication and UART2 is used for
output of debugging information. Please refer to the description in DC
Characteristics for UART output current level.
2. RESET is hardware reset pin and will be effective with VIL. Configuration
information will be remained after module reset. The module is already
designed with RC reset upon power-on.
3. TX and RX in UART0 are used for communication with external MCU
powered by 3V. Please refer to the description in 3.3. DC Characteristics for
UART output current level.

2.10 Additional testing, Part 15 Subpart B disclaimer
Part 15B required for the entire device even though module is 15C certified.
FCC Warning
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.
NOTE 1: Any changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. End users must follow the specific operating instructions for satisfying RF exposure
compliance.
Note 1: This module certified that complies with RF exposure requirement under mobile or fixed
condition, this module is to be installed only in mobile or fixed applications.
A mobile device is defined as a transmitting device designed to be used in other than fixed
locations and to generally be used in such a way that a separation distance of at least 20
centimeters is normally maintained between the transmitter's radiating structure(s) and the body of
the user or nearby persons. Transmitting devices designed to be used by consumers or workers that
can be easily re-located, such as wireless devices associated with a personal computer, are
considered to be mobile devices if they meet the 20 centimeter separation requirement.
A fixed device is defined as a device is physically secured at one location and is not able to be
easily moved to another location.
Note 2: Any modifications made to the module will void the Grant of Certificatio n, t his module is
limited to OEM installation only and must not be sold to end-users, end-user has no manual
instructions to remove or install the device, only software or operating procedure shall be placed
in the end-user operating manual of final products.
Note 3: Additional testing and certification may be necessary when multiple modules are used.
Note 4: The module may be operated only with the antenna with which it is authorized. Any
antenna that is of the same type and of equal or less directional gain a s an antenna t hat is
authorized with the intentional radiator may be marketed with, and used with, that intentional
radiator.
Note 5: To ensure compliance with all non-transmitter functions the host manufacturer is
responsible for ensuring compliance with the module(s) installed and fully operational. For
example, if a host was previously authorized as an unintentional radiator under the Supplier’s
Declaration of Conformity procedure without a transmitter certified module and a module is added,
the host manufacturer is responsible for ensuring that the after the module is installed and
operational the host continues to be compliant with the Part 15B unintentional radiator
requirements. Since this may depend on the details of how the module is integrated with the host,
Hangzhou BroadLink Technology Co., Ltd.shall provide guidance to the host manufacturer for
compliance with the Part 15B requirements.
Note 6: FCC ID label on the final system must be labeled with “Contains FCC ID:
2ATEV-BL3353-P” or “Contains transmitter module FCC ID: 2ATEV-BL3353-P”.
IC WARNING

Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following
two conditions:
(1) This device may not cause interference.
(2) This device must accept any interference, including interference th at may cause undesired
operation of the device.
L’émetteur/récepteur exempt de licence conten u dans le présent appareil est conforme aux CNR
d’Innovation, Sciences et Développement économique Canada applicables aux appareils radio
exempts de licence. L’exploitation est autorisée aux deux conditions suivantes:
1. L’appareil ne doit pas produire de brouillage;
2. L’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est
susceptible d’en compromettre le fonctionnement.
IC Radiation Exposure Statement:
This device and its antenna(s) must not be co-located with any other transmitters except in
accordance with IC multi-transmitter product procedures. Referring to the multi-transmitter policy,
multiple-transmitter(s) and module(s) can be operated simultaneously without reassessment
permissive change.
Cet appareil et son antenne (s) ne doit pas être co-localisés ou fonctionnement en association avec
une autre antenne ou transmetteur.
This equipment complies with IC RSS-102 radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator & your body.
Cet équipement est conforme aux limites d'exposition aux rayonnements IC établies pour un
environnement non contrôlé. Cet équipement doit être installé et utilisé avec un minimum de
20cm de distance entre la source de rayonnement et votre corps.
This module is limited to OEM installation only and must not be sold to end-users, end-user has
no manual instructions to remove or install the device, only software or operating procedure shall
be placed in the end-user operating manual of final products. Additional testing and certification
may be necessary when multiple modules are used.
Any changes or modifications not expressly approved by the manufacturer could void the user's
authority to operate this equipment.
The final end product must be labeled in a visible area with the following " Contains IC:
25062-BL3353P ".
