W600 Module
The W600 Module is a cost-effective 2.4GHz WiFi module support 802.11b/g/n. Seeed W600 Module is based
on the W600 chip which features ARM Cortex-M3 with 1MB on-chip flash and freeRTOS kernel.
We take the pins of the W600 chip out and put them on the back of the board, including
I2S/I2C/SPI/GPIO/PWM/UART/SDIO. In addition, this module has an on-board PCB Antenna, no need to
design the antenna separately, so you can quickly deploy the module to your own board. We also have made
CE/FCC certification for this module and you can use it directly for business projects.

Getting Started
To use the W600 Module, you need to use USB-to-Serial Tools to connect the RX/TX pins to your computer,
also you need to power this module with the 3.3v and GND pins.
!!!Note For mac, we found that some version of mac system can not recognize the on-board USB-to-Serial
chip CH330N, please check here for solution Mac os driver issue
We use the serial port tool sscom to send the AT command. You can use your favorite serial port tool, in case
you want to use sscom, you can download it Here.
What ever, please make sure you have checked the option AddCrLf, and set the baud rate to 115200
Tap AT+ then click SEND or press ++enter++ key to to check if the connection was successfully established.

Recommend using antenna which certified with this module mentioned in this manual. If you desire to
increase antenna gain and either change antenna type or use same antenna type certified, a Class II
permissive change application is required to be filed by us, or you (host manufacturer) can take responsibility
through the change in FCC ID (new application) procedure followed by a Class II permissive change
application, based on the new emissions testing. Please perform testing on frequency bands where the
antenna gain is highest, worst-case band-edges based on original filing, and only on frequency bands where
the antenna gain is highest.
1.2 RF exposure compliance instruction
This module is limited to installation in mobile application with a minimum separation distance of at least 20
cm from a person’s body, a separate approval is required for all other operating configurations, including
portable configurations with respect to §2.1093 and different antenna configurations. Host product
manufacturer shall at least provide information of minimum separation distance to end users in RF exposure
compliance statement to end users in their end-product manuals.

Please note that For a Class B or Class A digital device or peripheral, the instructions furnished the user
manual of the end-user product shall include statement set out in §15.105 Information to the user or such
similar statement and place it in a prominent location in the text of host product manual. Original texts from
FCC Rules are as following you may refer to:
For Class B
Note
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 Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. 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.
For Class A
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 FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.

including interference that may cause undesired operation.
§15.21 Information to user
Warning: changes or modifications not expressly approved by the party responsible for compliance could void
the user’s authority to operate the equipment.
RF Exposure compliance statement
This module complies with FCC 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 your
body. This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
