Module 5.3 Audio Transmitter Module Stereo GFSK transceiver Earphone Board Speaker KCX_ BT_ EMITTER 5(Antenna)

Suggest using two modules together, set as the transmitter and set as the receiver, to wirelessly transmit audio signals between the two modules.descriptionProduct model: KCX_ EMITER Name: Audio Boundary Dimensions: 23.5 * 15.5mmWorking voltage: 3.5-5VWorking current: 35mALaunch distance: 20 metersRF output power:+5dBm RF frequency range: 2402-2480MHzAudio dynamic range: 80dBAudio Total harmonic distortion: -70dBAudio frequency response: 20Hz-20KHzAudio signal-to-noise ratio: 95dBAudio input and output signal amplitude: 2Vpp Number of channels: 2 channels (stereo)Transmission delay: 250-300mSExplanation of external 2.4G antennaThe module integrates an IPX 1 with RF output interface for external 2.4G external antennas. When the module is applied inside a metal shell product, an external antenna is required. When using an external antenna, it is necessary to disconnect the PCB board antenna and plug in the IPX RF cable (the external 2.4G antenna needs to be provided by oneself, and the module does not come with an external antenna) as shown in the following figure.==========Package : TQFPModel Number : KCXBTEMITTERDissipation Power : 53 GFSKSupply Voltage : 1Application : AlarmCondition : NewType : Voltage RegulatorOrigin : Mainland ChinaPackage : TQFPisCustomized : YesModel Number : KCXBTEMITTERSupply Voltage : 1Application : OtherCondition : NewType : Voltage RegulatorOrigin : Mainland ChinaUnit Type : piecePackage Weight : 022kg 049lbPackage Size : 10cm x 10cm x 1cm 394in X 394in X 039in
