Note:
1. In default, UART2 (pin1 and pin2) are used for bypass communication and UART0
(pin16 and pin17) are used for output of debugging information and burning firmware. Please
refer to the description in DC Characteristics for UART output current level.
2. PDN is hardware reset for the module and will be effective with VIL. Configuration
information will be remained after module reset. The module has pull-up process for PDN
designed internally.
3. In default, PIN13 (GPIO8) is the PIN for external LED indicator to show the module
configuration status and output VIH after configuration is successful.
4. In default, PIN14 (GPIO5) is the module software reset PIN and will be effective with
VIH. The previous configuration information will be cleared after the module is reset (reset to
factory settings).
5. The module supports max 4 channels of external interruption simultaneously except
GPIO25 and UART0.
6. The ADC is 10bit with input voltage 0-2V
7. The power supply VDD should not be lower than 3.3V.
4.3. PCB Antenna
Please refer to Fig 2 for PCB antenna. Please avoid to place any electrical components,
wiring or grounding under PCB antenna area on main board and it’s better to leave this area
blank on PCB.

The following precautions should be considered during designing with PCB antenna:
1. Do not place any electrical components or grounding in antenna area on main board and
it’s better to leave this area blank on PCB.
2. It is recommended to not place any electrical components within 30mm range of module

antenna and not design any circuit or bond copper on main board under this area.
3. Do not use the module inside any metal case or containers with metal painting.
4. Keep the antenna of wifi module next to the edge of main board during design of PCB to
ensure better performance of antenna, as illustrated below.

5.1. UART Interface Design
For devices with 3.3V power supply, you can directly connect the device UART port with
module UART port according to the illustration in Fig Fig 7.
Fig 7 Circuit diagram (3.3V)
If your device is powered by 5V, you can refer to the circuit shown in Fig Fig 8 or design your
own circuit for power conversion. The value of resistor can be adjusted according to actual circuit
design.

Fig 8 Circuit diagram (5V)
5.2. Power Supply Requirement
If an LDO is used to supply the module with 3.3V power, C1 capacitor can be considered to
be used with 10u-22u; If a DCDC is used to supply 3.3V power, C1 capacitor can be considered to
be used with 22uF.
It is recommended to supply the module with power higher than 400mA to ensure enough
power supply to the module and avoid power down during data transmission.

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: This product has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This product generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with 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 product 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 receiver.
—Connect the equipment into 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.
Please take attention that changes or modification not expressly approved by the
party responsible for compliance could void the user’s authority to operate the
equipment.
This equipment complies with FCC/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.
2.2 List of applicable FCC rules
FCC Part 15.247
2.6 RF exposure considerations
This equipment complies with the FCC RF radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with a
minimum distance of 20cm between the radiator and any part of your body.
2.8 Label and compliance information
FCC ID label on the final system must be labeled with “Contains FCC ID:
2ATEV-BL3362T-P” or “Contains transmitter module FCC ID: 2ATEV-BL3362T-P”.

2.9 Information on test modes and additional testing requirements
Contact Hangzhou BroadLink Technology Co., Ltd. will provide stand-alone modular
transmitter test mode. Additional testing and certification may be necessary when
multiple modules are used in a host.
2.10 Additional testing, Part 15 Subpart B disclaimer
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.

Under Industry Canada regulations, this radio transmitter may only operate using an
antenna of a type and maximum (or lesser) gain approved for the transmitter by
Industry Canada. To reduce potential radio interference to other users, the antenna
type and its gain should be so chosen that the equivalent isotropically radiated power
(e.i.r.p.) is not more than that necessary for successful communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio
peut
fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé
pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et
son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse
pas l'intensité nécessaire à l'établissement d'une communication satisfaisante.
This equipment complies with FCC/IC RSS-102 radiation exposure limits set forth
for an uncontrolled environment. This eqipment should be installed and operated
with minimum distance 20cm between the radiator & your body.
