1.2 2.3 PCB Antenna a The gain of PCB B antenna on n this modu le is approxiimate 1.2dB,, as shown inn the figure belo ow. Simulateed radiation patttern of antenna gain The following precautions p should s be co onsidered du uring design ning with PC CB antenna: Do not placce any electrical compo onents or gro ounding in antenna a areaa on main board and it’s bettter to leave this area blaank on PCB.
1.3 3 Refe erence Design D 1.3.1 UART Interface D Design For devices with h 3.3V powe er supply, yo ou can direcctly connectt the device UART port with mod dule UART port p accordin ng to the illu ustration. If yo our device iss powered by b 5V, you caan refer to the t circuit sh hown in thee figure belo ow or desiign your ow wn circuit fo or power co onversion. The T value of o resistor ccan be adju usted acco ording to actual circuit design.
1.3 3.2 Powe er Supply y Requirrement If an LDO is used to supply thee module with w 3.3V power, C1 caapacitor can n be considered to be used d with 10u- 22u; If a DC CDC is used d to supply 3.3V power, C1 capacitor can be consid dered to be used with 22uF 2 It is recommended to supply the module witth power hig gher than 4000mA to en nsure enough po ower supply to t the modu ule and avoid power dow wn during d data The module is designe ed with 2x 3..3V pins.
