User Manual
Fender FMA BT-FTSW-USB PCBA (PN 7710068000) Manual and Spec, revision 1.0 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.

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.
