1. Power Supply
The CM-43438-V1 module supports SDIO bus power level DC 3.3V, 2.8V or 1.8V. If the voltage level
of SDIO bus is DC 3.3V, like most PC or NB, then CM-43438-V1 can be powered by this single DC 3.3V
from SDIO bus. But if the voltage level of SDIO bus is DC 2.8V or 1.8V, most the embedded platforms.
WiFi interface and SDIO bus power option
The WiFi interface on CM-43438-V1 is SDIO, and it works under different SDIO bus power conditions such
as DC 3.3V, 2.8V or 1.8V.
Please open the connector of J4 to provide an additional DC 3.3V power supply to CM-43438-V1 when it be
used under SDIO bus power of DC 2.8V or 1.8V(The additional DC 3.3V is supplied from a PWM circuit from
power of micro-USB, so remember to connect DC power into the micro-USB).
Please close the connector of J4 when SDIO bus power is DC 3.3V.

Bluetooth interface
The Bluetooth interface on CM-43438-V1 is through UART, provided signal of UART Tx, Rx, RTS, CTS pins.
2. Power on sequence
1. Use an USB cable to connect the USB connector of EVB to a PC USB port, to supply DC 5V to
EVB.
2. Plug in SD adapter into your target platform.
3. Your platform will acknowledge the CM-43438-V1 module.

FCC Warning
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: Any changes or modifications to this unit not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users
must follow the specific operating instructions for satisfying RF exposure compliance.
Note 1: Compliance of this device in all final host configurations is the responsibility of the Grantee.
OEM integrators are responsible to satisfy RF exposure requirements. SAR evaluation is valid for portable,
mobile and fixed applications.
Note 2: Any modifications made to the module will void the Grant of Certification, this module is limited to OEM
installation only and must not be sold to end-users, end-user has no manual instructions to remove or install the
device, only software or operating procedure shall be placed in the end-user operating manual of final products.
Note 3: The device must not transmit simultaneously with any other antenna or transmitter.
Note 4: To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring
compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as
an unintentional radiator under the Declaration of Conformity procedure without a transmitter certified module
and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and
operational the host continues to be compliant with the Part 15B unintentional radiator requirements. Since this
may depend on the details of how the module is integrated with the host, CC&C Technologies, Inc. shall provide
guidance to the host manufacturer for compliance with the Part 15B requirements.
Note 5: FCC ID label on the final system must be labeled with “Contains FCC ID: PANCM43438V1”
The transmitter module must be installed and used in strict accordance with the manufacturer's instructions as
described in the user documentation that comes with the host product. CC&C Technologies, Inc. is responsible for
the compliance of the module in all final hosts.
