Module Description
The Fender FMA BT-FTSW-USB PCB Assembly is an auxiliary PCB used in the family of Fender Modular
Architecture (FMA) products. The board has a USB port with a micro AB connector, a Fender Footswitch
port with a ¼” phone jack and a wireless module.
Circuit Description/Theory of Operation
There are three main sections of the circuit:
• Bluetooth module (FreeWings FW3817-30), antenna, & audio output circuit
• USB port
• Footswitch port
The USB circuit consists of ESD protection components and a micro AB USB connector. The Footswitch
circuit consists of ESD protection components and a ¼” phone jack connector. Both of these circuits are
unrelated to the Bluetooth section, and are shared on the PCB for mechanical convenience.
The FreeWings module is a complete Bluetooth implementation with analog audio output. An F-style
antenna is connected to the RF output of the module through a test switch and matching network. The
module is powered with a 3.3V DC supply and digital ground. The PCB is dual layer with digital ground
plane sections stitched together on both sides where possible. The analog stereo audio output from the
module is buffered by an op-amp stage before sending back to the host system. The analog audio buffer
circuit has a separate power supply and ground system to isolate it from digital noise.
All Bluetooth functionality is controlled by on-board firmware. But the module may be accessed for test
through the SPI port to a computer interface module (available from FreeWings). A description of
specific commands for Bluetooth is beyond the scope of this document and can be found in
documentation from FreeWings or CSR for the CSR8630 chipset.

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.
WARNING: Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
LABEL OF THE END PRODUCT:
The final end product must be labelled in a visible area with the following:
"Contains FCC ID: XQW-FMAPR4475"
If the size of the end product is smaller than 8x10cm, then additional FCC part 15.19 statement is
required to be available in the users manual: 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.
RF Exposure
This device has been evaluated and shown compliant with the FCC RF Exposure limits under fixed
exposure conditions (antennas are greater than 20cm from a person's body) when installed in certain
specific OEM configurations.
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment.
This transmitter must not be co-located or operating in conjunction with any other antenna or

3 Electrical Characteristics
7.1 Reset
FW3817-30 module is reset from several sources.We suggest to use power-on reset,that means to leave the
RSTn pin floating:
RSTn pin pulled low for minimum 5ms
Power-on reset, leaving the RSTn pin floating. It should be that it was 0V voltage at any pin before reset.
USB charger attach reset
Software configured watchdog timer
7.2 Power on and power off
FW3817-30 module is power on from two sources:
VREG_EN pin pulled high for minimum 100ms when VBAT pin is in the status of stable power.
VREG_EN pin pulled high from low when VBAT pin is in the status of stable power.
The wrong timing sequence of VREN_EN and VBAT will lead to error of power on.
FW3817-30 module is power off from two sources:
VREG_EN pin pulled high for minimum 100ms when VBAT pin is in the status of stable power.
VREG_EN pin pulled low from high when VBAT pin is in the status of stable power.
The wrong timing sequence of VREN_EN and VBAT will lead to error of power off.
7.3 I/O
The driver power voltage of all the PIO port is 1.8V inside of the module.
7.4 Battery Charger
FW3817-30 module provides two kinds of battery charger controls.
The internal charger circuit can provide up to 200mA of charger circuit.
The module controls an external pass transistor which can provide 500mA of charger circuit.
7.5 USB
USB_P and USB_N can be used to updating software or USB audio.Both of them request that VCHG pin must
be supplied 5V power.The two data signals do not need any resistance or capacitance.
