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.

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 Certification, 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. 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 as an antenna that 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 Suppliers 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 This device contains licence-exempt transmitter(s) that comply with Innovation, Science and Economic Development Canadas 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 that may cause undesired operation of the device. Lmetteur/rcepteur exempt de licence contenu dans le prsent appareil est conforme aux CNR dInnovation, Sciences et Dveloppement conomique Canada applicables aux appareils radio exempts de licence. Lexploitation est autorise aux deux conditions suivantes:
1. Lappareil ne doit pas produire de brouillage;
2. Lappareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible den 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 tre co-localiss 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 quipement est conforme aux limites d'exposition aux rayonnements IC tablies pour un environnement non contrl. Cet quipement doit tre install et utilis 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:
