FSC-BT691 Datasheet 4.4 General Purpose Digital IO There are 6 general purpose digital IOs defined in the module. All these GPIOs can be configured by software to realize various functions, such as button controls, LED drives or interrupt signals to host controller, etc. Do not connect them if not use. The I/O type of each I/O pins can be configured by software individually as Input or Push-pull output mode.
FSC-BT691 Datasheet recommend that you adhere to the correct CTS/RTS handshaking protocol for proper operation. Table 3: Possible UART Settings Parameter Possible Values Baudrate Minimum 1200 baud (≤2%Error) Standard 115200bps(≤1%Error) Maximum 921600bps(≤1%Error) Flow control RTS/CTS, or None Parity None, Odd or Even Number of stop bits 1 /1.5/2 Bits per channel 5/6/7/8 When connecting the module to a host, please make sure to follow .
FSC-BT691 Datasheet 5. ELECTRICAL CHARACTERISTICS 5.1 Absolute Maximum Ratings Absolute maximum ratings for supply voltage and voltages on digital and analogue pins of the module are listed below. Exceeding these values causes permanent damage. The average PIO pin output current is defined as the average current value flowing through any one of the corresponding pins for a 100mS period.

The purpose of this zone is to preheat the PCB board and components to 120 ~ 150 C. This stage is required to distribute the heat uniformly to the PCB board and completely remove solvent to reduce the heat shock to components.

HARDWARE INTEGRATION SUGGESTIONS 9.1 Soldering Recommendations FSC-BT691 is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile used is dependent on the thermal mass of the entire populated PCB, heat transfer efficiency of the oven and particular type of solder paste used. Consult the datasheet of particular solder paste for profile configurations.

FSC-BT691 Datasheet Antenna Wrong Antenna Antenna PCB PCB PCB Better Best Figure 10: Recommended Trace Connects Antenna and the Module Routing of the RF-connection underneath the module should be avoided. The distance of the micro strip line to the ground plane on the bottom side of the receiver is very small and has huge tolerances. Therefore, the impedance of this part of the trace cannot be controlled. Use as many vias as possible to connect the ground planes. 10. 10.

FSC-BT691 Datasheet 11. Warning FCC Statements (OEM) Integrator has to assure compliance of the entire end-product incl. the integrated RF Module. For 15 B (§15.107 and if applicable §15.109) compliance, the host manufacturer is required to show compliance with 15 while the module is installed and operating. Furthermore the module should be transmitting and the evaluation should confirm that the module's intentional emissions (15C) are compliant (fundamental / out-of-band).
