5 Pin Definition & Encapsulation

5.1 Pin Definition

The signal connection uses 28pin SMD pad of stamp hole(half hole).

Note: M660 module IO interface level is 2.8V.

Because the module IO uses 2.8V power supply system, the maximum input voltage of all

the IO interface can not exceed the maximum 3.3V, otherwise it may damage the module

IO. Considering the signal integrality designing reasons,while the external circuit use 3.3V

power system the IO interface output voltage will exceed 3.3V because of overshoot

phenomenon, sometimes can even reach 3.5V.Therefore,the IO pin of the module will be

damaged if 3.3V IO signal is connected to 2.8V IO of the module directly.

9 Assembling

In order to prevent the product of M660 from being affected with damp, caused by using

the SMT way to perform the furnace welding, in the process of production and use of the

costumer, we employ the way of damp-proof packing, such as Aluminum Foil Bag,

desiccating agent, Humidity Indicator Cards, Suck plastic trays, and vacuolization. As a

result the product is kept dry and its life span will be long.

In order to make the SMT way easy, we use the tray to load the product. The user only

needs to install it in the chip machine according to the fixed direction.

M660 storage and SMT notes, please refer to <Neoway module SMT reflow production

recommendation_V1.0>.

FCC Caution

Any Changes or modifications not expressly approved by the party responsible for

compliance could void the user’s authority to operate the equipment.

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 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.

FCC Radiation Exposure Statement:

This equipment complies with FCC 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.

This transmitter must not be co-located or operating in conjunction with any other antenna

or transmitter.
