The pad is retracted and offset, and the PCB pad is expanded from the module pad do not affect the use of the module. 3Antenna layout requirements

(1) the installation position on the motherboard, the following two ways are recommended:

Scheme 1: put the module on the edge of the motherboard, and the antenna area extends out of the edge of the motherboard. 12 SHENZHEN B&T TECHNOLOGY Co., Ltd ZHONGSHAN B&T TECHNOLOGY Co., Ltd Scheme two: put the module on the edge of the motherboard, the edge of the motherboard in the antenna position empty an area.

(2) in order to meet the performance of on-board antenna, it is forbidden to place metal parts around the antenna, away from high-frequency components.. 4. power supply

(1) Recommended 3.3 V voltage, peak currentabove500 mA

(2) It is recommended to use LDO for power supply; if DC-DC is used, the ripple is recommended to be controlled within 30mV.

(3)It is recommended to reserve the position of the dynamic response capacitor for the DC-DC power supply circuit, which can optimize the output ripple when the load changes greatly.

(4).It is recommended to add ESD devices to the 3.3V power interface 5.GPIO port use

(1) module periphery have lead some GPIO interfaces, if you need to use,it is recommended the resistance of 10-100 ohms in series on the IO port. This can 13 SHENZHEN B&T TECHNOLOGY Co., Ltd ZHONGSHAN B&T TECHNOLOGY Co., Ltd suppress overshoot, and two sides of the level more stable.and help for both EMI and ESD.

(2) The IO ports for pull up and down, please refer to the specification, this will affect the module startup configuration.

(3)The module IO port is 3.3 V, if the main control does not match the IO level of the module, the level conversion circuit needs to be added.

(4) if the IO port is directly connected to the peripheral interface, or pin and other terminals, it is recommended to reserve ESD device near the terminal. Graph level conversion circuit 7Packaging information As shown below, the BW15 is packed in ribbons:

14 SHENZHEN B&T TECHNOLOGY Co., Ltd ZHONGSHAN B&T TECHNOLOGY Co., Ltd OEM/Integrators Installation Manual Important Notice to OEM integrators INTEGRATION INSTRUCTIONS FCC rules The BW15 is an WIFI+BT Module Module. It operates on the 2400 ~2500 MHz band and, therefore, is within U.S. FCC part 15.247 standard. Modular installation instruction 1,BW15 Integrates high-speed GPIO and peripheral interface. Please pay attention to the installation direction (pin direction). 2,Antenna could not be in no-load state when module is working. During debugging, it is suggested to add 50 ohms load to the antenna port to avoid damage or performance degradation of the module under long-time no-load condition. 3,When the module needs to output 31dBm or more power, it needs a voltage supply of 5.0V or more to achieve the expected output power. 4,When working at full load, it is recommended that the entire bottom surface of the module be attached to the housing or heat dissipation plate, and it is not recommended to conduct heat dissipation through air or screw column heat conduction. 5,UART1 and UART2 are serial ports with the same priority. The port which receives commands returns information.
