5km Long Range Feedback Receiver and Transmitter Kl-Bt01 V1.0

5Km feedback transmitter and receiver mdoule KL-BT01 V1.0   KL-BT01 V1.0  is our currently developed a new bidirectional receiver module. Its core is the use of spread spectrum communication techniques, greatly enhancing the anti-jamming performance. 1. Characteristic: Ø  High sensitivity, -148dBm. Ø  Small size (52*28*14mm). Ø  Low power consumption. Ø  Low self emission, can easy pass all kinds of certification.    2. Specification: Ø  Frequency: 434/868/915MHz Ø  Working Voltage: DC 2.7-3.6V, optional Ø  Working Current: 16mA Ø  Modulation: ASK/OOK Ø  Emission Current: 110mA Ø  Working Temperature: -10~70°C   3. Applications: 1). Garage door and gate openers 2). Electric windows, barrier, etc. 3). Remote controls and smart home alarm 4). Low baud rate for data transmission 4. Pin Assignment: PinPin FunctionD0Data OutD1Data OutD2Data OutD3Data OutGNDGNDEmptyEmptyVCCVCC5.Usage       A.Match Code: Press match code button K1 for 3seconds, LED indicator lights, and press any buttons on remote control. When LED flashes 2times, it means finishing matching code.       B.Delete Code: Press K1, not let go the hand until LED flashes 3times, and then delete code successfully. C. Select output mode: can use dip switch to select output mode: Push no.1 on dip switch to ON position, output Latch(interlock); Push no.2 on dip switch to ON position, output Toggle(self-lock); no.1 and no.2 are not pushed to ON position, output Momentary(non-lock) no.1 and no.2 are pushed to ON position, Setting is invalid, no output.   This receiver module is a bidirectional transmitting& receiving module, matching with bidirectional remote control. Customer can choose to return signal or not. If yes, push no.3 on dip switch to ON position (corresponding S1 on remote control).This receiver module will transmit a signal after receiving it from bidirectional remote control. When bidirectional remote control receives the signal, the buzzer will send the sound 'dip-' And that indicates bidirectional remote control is normal to receive communication     5.
