UART 0 is used for general transparent transmission , and UART1 is used for the output of debug information,and the serial ports output level is described with reference to DC characteristics,by default. 2.
1.2.3 Built-in Antenna The support of this module selects PCB board to carry antenna,and in 2.4G~2.5G frequency range,antenna port S11 is less than -10dB,the about 1.5dB of antenna gain.
When selecting the PCB antnna,the module in place should pay attention to the following points when ： 1. Components and parts and floor files can not be placed in user PCB base plate and module antenna corresponding region,preferably can be with PCB hollow out that should the zone. 2. Do not place any components and parts in the suggestion module antenna area 10mm,the module base plate is also avoided cabling as for as possible in this zone,forbids applying copper 3.
1.3The Hardware Reference Design 1.3.1 The UART Interface Design For the equipment of 3.3V power supply,can equipment of serial and module serial ports directly be linked to each other by the diagram circuit and accomplish communication； If the 5V power supply unit can or design the associated level change-over circuit voluntarity with reference to following circuit,resistance value can be adjusted according to side circuit. 1.3.2 Power Reguirements Give module for power supply if produce 3.
