5. Layout and Soldering Considerations

To make sure wireless performance is at its best condition, please layout the module on the
carrier board as below instructions.

5.1 Carrier board under the antenna area of the module like the picture;

5.2 Keep out enough area for the antenna area;

5.3 Reflow profiles are to be selected according to standard manufacturing process;

5.4 The soldering temperature should be less than 206℃;

5.5 The module should be placed far away other low frequency and digital circuits;

5.6 The MS50 series modules contain highly sensitive electronic circuitry and are Electrostatic
Sensitive Devices (ESD). Handling the MS50 series modules without proper ESD protection
may destroy or damage them permanently.

Recommended Layout for the Carrier Board

*PCB: It’s the mother board / carrier board.

6. UART Commands

Please refer to the UART commands document to know more.

FCC Caution：
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.

Any changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.

NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital devic e, pu rs ua n t to P art 1 5 of the FCC Rule s . The s e limits are designed to provide
reasonable protection against harmful interference in a residential insta lla t ion . Th is 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 antenn a.

-- 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.

To maintain compliance with FCC’s RF Exposure guidelines, This equipment should be
installed and operated with minimum distance between 20cm the radiator your body: Use
only the supplied antenna.
