2.4 GHz Wi-Fi Module User Manual
General Description
The 2.4 GHz Wi-Fi module is an 802.11b/g/n solution containing RF frontend circuitry, baseband, MAC,
Clock Management and Power Management for direct battery attach. The module is designed to be
soldered to a PCB using with three external interfaces, power, SPI bus and u.fl antenna. The module
is designed for use within the mobile devices category with the antenna placed greater than 20 cm
from the body. The module comes fully tested and calibrated at the factory.
Placement of FCC ID on the finished product
Use of this module requires placement of the FCC ID on the exterior of the finished product. The FCC ID
must be visible on the exterior of the product and cannot be placed on a removable part. The FCC ID
should be permanent (e.g. stamped, etched, engraved, printed with permanent ink or on a label with
permanent adhesive, etc). Hand held devices may be permitted to place the FCC ID in the battery
compartment under certain restrictions contained within KDB 784748 section 4:
https://apps.fcc.gov/oetcf/kdb/forms/FTSSearchResultPage.cfm?id=27980&switch=P
The finished product label must include the FCC ID of the incorporated module preceded by the phrase
“This device contains” or any similar such verbiage conveying similar meaning:
This device contains FCC ID: 2ADXI-SK370-00020
Or more simply:
Contains FCC ID: 2ADXI-SK370-00020
Product Label Requirement
The ID Label of the finished product must include the following statement. However, devices which are
smaller than 4x4” are permitted to place this statement in the instruction manual, pamphlet or
packaging in which the device is marketed.
“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..”
Usage Restrictions
“Changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment.”
Manual for Products
Only one of the below statements is required to be in the finished product’s users manual, depending on
whether the product is either Class A or Class B.
Part 15 Class A Devices
“Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the F
to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This
can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful int
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to co
expense.”
Part 15 Class B Devices
“This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rul
provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can ra
if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, t
interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television recep
turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measure
-- 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”
Electrical Data
Absolute Maximum Ratings
The absolute maximum ratings specify the values beyond which the device may be damaged
permanently. Exposure to absolute maximum ratings conditions for extended periods of time may
affect reliability. Each condition is applied with all other values kept within the recommended operating
condition.
Recommended Operating Conditions
The recommended operating conditions specify the values in which region the device is operational
meeting specification.

WLAN Firmware
The firmware is executed from on-chip ROM. Firmware patches are downloaded from host at Power on
Reset, or loaded into RAM from a serial Flash Memory connected to the SPI interface. The firmware
implements the full IEEE 802.11b/g/n wireless LAN MAC protocol, an embedded IP stack together with a
few commonly used applications that can be easily configured and controlled via the chip interface.
The wireless LAN MAC stack supports basic service set (BSS), Mobile AP and WiFi Direct. Low-level
protocol functions such as RTS/CTS, acknowledgement, fragmentation, defragmentation, frame
encapsulation (802.11h/RFC1042) and automatic beacon monitoring / scanning are handled by the
baseband MAC. The IP stack supports TCP, UDP, RTP, and ICMP over IPv4. On top of the IP stack there is
web server with support for Server-Side Includes (SSI) and Common Gateway Interface (CGI) available.
The web pages can be customized via the serial interface.
4.7.1 Features

• Supports WPS 2.0
• Supports 802.11n up to MCS6 (Tx/Rx). Supporting block ACK, MIMO 1x1 & 2X1, STBC, A-MPDU
aggregation and 0.4us guard interval.
• WMM Power Save U-APSD
• Multiple queue management to fully utilize traffic prioritization defined by the 802.11e standard.
• 802.1h/RFC1042 Frame encapsulation.
• Scattered DMA for optimal CPU off load on Zero Copy data transfers operations.
