Possible to use as a LED output depend on firmware (driver) version. Regardless of the I/O supply
(1.8V or 3.3V), the supply to the actual board LED always need to use 3.3V on the other end of the
LED and works as open drain circuitry in that case. LED current limiting resistor should be used.
Maximum sink to the ground current - 10 mA.
Should be provided from external source in case of power save operation modes necessity. Not
required for full power mode and for automotive use (firmware & driver version 14.44). Mandatory
for all other releases with sleep mode support. Sleep clock signal requirements: frequency
32.768kHz ±250ppm, low level from 0 to 0.25V, high level from 0.8 to 2.0V, duty cycle 20-80%,
slew rate less than 100nS (10-90%).
Leave it unconnected when 32.768KHz Sleep Clock provided, pull down by 47K resistor for Sleep
Clock less operation.

Reference Design
Overview
Reference design shows how to connect a WiBear11n module to the host controller. WLAN and Bluetooth
(BT3.0 HS + EDR) may be connected to the host simultaneously over the SDIO bus. The layout is equipped
with the possibility to either use an onboard antenna or an external antenna connected via coaxial connector by
means of setting of jumper R7 or R8. Host interface voltage can also be changed by jumper J6. The readymade reference design is available as WiBear11n Evaluation Kit from Lesswire AG.

Version 1.10
Mounting process
The WiBear11n is a surface mount module supplied on a 6-layer FR4-type PCB with gold plated connection
pads and produced in a lead-free process with a lead-free soldering paste.
Modules rated at moisture sensitivity level 3. See moisture sensitive warning label on each shipping bag for
detailed information. After opening the dry pack, modules must be mounted within 168 hours in factory
conditions of maximum 30°C/60%RH or must be stored at less than 10%RH. Modules require baking if the
humidity indicator card shows more than 10% when read at 23±5°C or if the conditions mentioned above are
not met. Please refer to J-STD-033B standard for bake procedure.
Module is compatible with industrial reflow profile for RoHS/Pb-free solders, Sn96.5/Ag3.0/Cu0.5 solder is a
right choice. Use of "No Clean" soldering paste is strongly recommended, cleaning the populated modules is
strongly discouraged - residuals under the module cannot be easily removed with any cleaning process.
Cleaning with water can lead to capillary effects where water is absorbed into the gap between the host board
and module. The combination of soldering flux residuals and encapsulated water could lead to short circuits
between neighboring pads.
Only a single reflow soldering process is encouraged for host boards with WiBear11n modules.
The reflow profile used is dependent on the thermal mass of the entire populated PCB, heat transfer efficiency
of the oven and particular type of solder paste used. Since the profile used is process and layout dependent,
the optimum profile should be studied case by case. Recommendations below should be taken as a starting
point guide. In case of basic information necessity please refer to J-STD-020C standard.
