Note：
1. UART 0 is used for general transparent transmission , and UART1 is used for the
output of debug information,and the serial ports output level is described with
reference to DC characteristics,by default.
2. NRST is that module hardware resets ,and low level is effective ,restars after
module resets,adn keeps original configuration information. The inner existing
RC electrify restoration circuit of module itself.
3. Under the default situations,PIN 12 (GPIO33) is the network light pin,is used for
external LED,the configuring condition of indicating module.
4. Under the default situations,PIN11 (GPIO35) is the module software reset pin,and
high level is effective,and former configuration information of the back module
that resets is eliminated similar factory reset.
5. All GPIO all support PWM output.
6. TX and RX are used for communicating with the ppu of 3V power supply among
the UART0,and the serial ports output level is described with reference to
3.3joint DC characteristics.
7. Unsettled processing is done in the GPIO suggestion that is not used,and forbids
on the circuit that to GPIO35,GPIO37 does and draws processing.
1.2.3 Built-in Antenna
The support of this module selects PCB board to carry antenna,and in 2.4G~2.5G
frequency range,antenna port S11 is less than -10dB,the about 1.5dB of antenna gain.
antnna gain emulation rediation diagram
The antnna port S11simulation curve
When selecting the PCB antnna,the module in place should pay attention to the
following points when ：
1. Components and parts and floor files can not be placed in user PCB base plate and
module antenna corresponding region,preferably can be with PCB hollow out that
should the zone.
2. Do not place any components and parts in the suggestion module antenna area
10mm,the module base plate is also avoided cabling as for as possible in this
zone,forbids applying copper
3. Use in the mould that module is not placed on metal-back or has metal to spray
paint.
4. The user is when the pcb board layout in suggestion,as far as possible with the
antnna of wifi module near bottom edge,be shown in the following figure,to
guarantee the good performance of antnna.
1.3The Hardware Reference Design
1.3.1 The UART Interface Design
For the equipment of 3.3V power supply,can equipment of serial and module serial
ports directly be linked to each other by the diagram circuit and accomplish
communication；
If the 5V power supply unit can or design the associated level change-over circuit
voluntarity with reference to following circuit,resistance value can be adjusted
according to side circuit.
1.3.2 Power Reguirements
Give module for power supply if produce 3.3V voltage through LDO, then the
capacitance of C1 can be considered with 10u ~ 22u;Give module for power supply if
produce 3.3V through the DCDC power supply, the electric capacity of C1 can be
considered with 47u or bigger alminium electrolytic condenser。
Please guarantee that power supply can provide enough big electric current, power
down occur to avoid module when sending data, the maximum input current of
suggestion module is greater than 330mA
Module leaves two 3.3Vpin, both can select a pin to module voltage to be provided
arbitrarily, also can supply power simultaneously by two pin

This equipment 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 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 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.
The distance between user and device should be no less than 20cm.
The Wifi module is designed to comply with the FCC statement. FCC ID is
2ACDZ-3303-SBSL. The host system using Wifi module, should have label
indicated it contain modular FCC ID: 2ACDZ-3303-SBSL
